Phylloxera, the Other Infection

It was a month before harvest. We were told that our grape order with a Walla Walla vineyard could not be fulfilled due to a light crop this year. Thinking that the unseasonably warm weather might be the cause, we switched our order and went with a Yakima vineyard instead. Then through the grapevine (no pun intended), I learned about the real culprit - phylloxera!

Phylloxera Plague

You may have heard of the phylloxera epidemic in Europe back in the 19th century. The vineyards there were severely decimated, bringing the wine industry to its knee. It started when American vines were brought across the Atlantic Ocean to be studied. Unfortunately, little pesky stowaways went along with them and somehow snuck into the vineyards.

Phylloxerae are microscopic insects that feed on the leaves and roots of the grapevines. In the roots, they can cause critical damage and introduce a secondary bacterial or fungal infection, eventually starving the vines of nutrients and water. It was estimated that over 40% of the French vineyards were devastated over 15 years during the plague.

Champagne vineyards once devastated by phylloxera
Early attempts to contain the plague ranged from chemicals to pesticides. Some vineyards even introduced predators like toads and chicken to control the phylloxera population. These attempts were in vain. The only viable solution was to graft European vines onto phylloxera-resistant American rootstocks. These rootstocks have developed a natural defense against the insect. When bitten, the American root exudes a sap to clog the louse's mouth and then forms a layer of tissue to protect itself from any secondary infection. 

The grafting approach was wildly successful in saving the European grapevines, also known as Vitis vinifera. You can thank the American rootstock as you sip your glass of Bordeaux or Barolo.

Dodging the Phylloxera Bullet?

Many vineyards growing Vitis vinifera grapes have preemptively avoided the threat of phylloxera by planting only vines that are grafted on resistant rootstocks. But there are areas in Europe and beyond that have remained unscathed by the louse. Apparently, phylloxera does not survive well in the slate soil of Mosel or the volcanic soil of Mount Etna. Grapevines in those areas are still grown in their native rootstocks.

Phylloxera also tends not to thrive in cooler climate. Until recently, Washington had been virtually phylloxera-free and was able to grow Vitis vinifera in their native rootstocks as well. However, with climate change, phylloxera has started making inroads into a few Walla Walla vineyards leading to an outbreak in 2019. 

Phylloxera does not tolerate cold winter
Reluctant to give up the native rootstocks, many Walla Walla vineyards hope to contain the spread of phylloxera through better sanitation practices and extensive quarantine protocol. Several vineyards have required boots to be disinfected and also placed a limit on visitor traffic. If nothing else, this may slow the spread and buy the vineyards time to plan for the eventual transition to American rootstocks.

While there is always the debate about the quality of wine being affected by grafted vines, the truth is that it hasn't hurt sales in Napa or Bourgogne. However, ripping off infected vines and replanting with new ones is very costly. Additionally, it often takes about three years before a new vine can produce viable grapes. 

One wonders how that all may play into the psyche of Walla Walla wineries as they deal with phylloxera. Are they going to be doers or deniers?

Pandemic Winemaking

I have enjoyed winemaking as a hobby. I love dreaming about the new vintage in the spring while sourcing the grapes, waiting in anticipation for harvest in the fall, and immersing myself in the process of fermentation all winter. More than that, I adore the camaraderie among fellow winemakers as we process freshly harvested grapes, press the grapes, rack the wine, and finalize it for bottling. It is hard work with grapey messiness, but it is always rewarded with wonderful food and wine, friendship and laughter.

Pre-pandemic celebration of a vintage

Then came the pandemic. While the wine yeast and malolactic bacteria remained unaffected, the whole social aspect of winemaking was very much altered. 

Pandemic Harvest

When harvest rolled around last year, the vaccines were not yet available. We had nothing but masks and sanitizers, relying on good sense and reasonably decent weather to keep us outdoor and socially distanced.

Freshly harvested grapes
Like prior years, the winemakers arrived at the crush site waiting for the grapes. Only this time, our excitement was contained behind the masks. There was a sense of uncertainty as we navigated working together while keeping six feet apart. 

Once we were assigned our duties, it was like clockwork. Some of us set up and sanitized the crusher/de-stemmer. Others raked the grapes into crates, weighing and distributing the allotments. We then crushed and de-stemmed the grapes. When all the grapes were processed, we cleaned up and stored the equipment.

There was a subdued sense of elation when we were done. Yet in our usual post-crush sticky grapey messiness, there were no high fives nor pats in the back. We merely exchanged nods with smile in our eyes as we claimed our respective portions of the crushed grapes to bring home.

Pandemic Fermentation

While we typically complete alcoholic fermentation separately, we would get together to press the grapes and have a potluck. Last fall, sharing food was not an option. Instead I made a hearty batch of chili for post-press nourishment. We sat six feet apart in a heated garage with the door lifted, chowing down hot chili with corn bread and washing them down with wine.

Pre-pandemic racking and tasting

After press comes periodic racking. In pre-pandemic days, we would rack our wine together because we share a single barrel.  Each time we met was another opportunity for a potluck and sharing bottles of wine. Last year, however, we chose against group racking. Instead, everyone left their carboys of wine in my garage. Throughout fall and winter, I racked and tasted the group's wine, reporting out tasting notes. (Our dog Jipp was my co-winemaker.)

My pandemic co-winemaker
By bottling time, it was summer, and the weather had warmed up considerably. We were all fully vaccinated and happy to ditch the masks while maintaining social distance. With the garage door wide open, we formed an assembly line, prepping bottles, siphoning wine, corking, and cleaning up. We celebrated the 2020 vintage, sipping hot coffee and feasting on the spread of sweet and savory breakfast pastries, fresh fruit, and delectable limoncello curd yogurt.

Another Pandemic Vintage?

It would have been great if the pandemic ended with that vintage. In July, it was looking optimistic with an all-time low COVID-19 hospitalization, coupled with a high vaccination rate. Then the delta variant struck. By August, COVID-19 hospitalization had gone up by almost ten times! Non-urgent procedures are being cancelled and visitor policy has become more restrictive as the hospitals hunker down for yet another surge. 

Stepping into the my garage cellar, I can't help but wonder - Is 2021 going to be another pandemic vintage?

What we do have now that we didn't have then are vaccines, more effective treatments, and substantially more knowledge and experience in dealing with the virus. Yet, if there is anything I have learned, it is anything can change and change fast. So I am going to keep one eye on the vineyards and the other eye on the hospitals and hope for the best.

Pét-Nat, Pet What? The Hipster Sparkler

You know Champagne and Prosecco, the two styles of sparkling wines. Their key distinction lies in the method of second fermentation, where the liqueur de tirage (mixture of yeast, sugar, and wine) is introduced to the still wine base to produce bubbles. Second fermentation takes place in the bottles for Champagne (known as the traditional method) and in the tank for Prosecco (known as the Charmat method). While wine connoisseurs argue which method is better, there is yet another sparkling wine that does not even go through a second fermentation.

Hello, Pét-Nat, the hipster sparkler! 

Short for pétillant-naturel (French for "naturally sparkling"), pét-nat wines have gained in popularity in recent years with the increased demand for more natural and less manipulated wines. Fad aside, the pét-nat method (known as the ancestral method) was probably how the first sparkling wines were made. This production method dates back to the 1500's. 

It is not hard to imagine how pét-nats might come about by accident. Back in the days without modern equipment and knowledge to measure and monitor the decrease in sugar content during alcoholic fermentation, wine was sometimes bottled before the process was complete. The yeast then resumed converting sugar to alcohol while releasing carbon dioxide as a byproduct in the bottle. So when the bottle was popped, there was a slight effervescence in the wine from the carbonation.

Here are three things to know about pét-nat, and why your hipster friends may love them.

Low Alcohol

Pét-nat wines are made with a single alcoholic fermentation process that starts outside and continues inside the bottle. Champagne and Prosecco, on the other hand, start with still wine as a base that is layered on with the alcohol from the second fermentation.

As a result, most pét-nat wines run in the range of 10-12% ABV, relatively lower compared to the 12-12.5% ABV found in a Champagne or a Prosecco.

A Tad Fizzy

Pét-nat wines rely solely on whatever is left of the primary fermentation in the bottle for carbonation. Without the liqueur de tirage to fuel more yeasty activity, pét-nats will not achieve the level of effervescence that a Champagne or a Prosecco produces. However, if you enjoy wine with just a little fizz, pét-nats will deliver on that.

For the physicists among us who can relate to bars as the units of measure for pressure, pét-nats generally come up to about 2.5-3 bars. That is somewhere between semi-sparkling and a less sparkling wine. In comparison, Champagnes and Proseccos range between 5.5-6 bars.

Hipster Rustic

While Champagne and Prosecco winemaking can be highly involved to achieve a certain finesse and/or a consistent house style, the making of pét-nats requires a light hand. Some pét-nat makers may be more precise than others at achieving the right level of sugar content prior to bottling, even if it is just to prevent bottle explosion in the cellar. But generally, pét-nats are described as unpredictable and less tamed. 

Crown corks by Adam Wilson on Unsplash

Then there is the question of disgorgement that is practiced by Champagne makers. Disgorgement is the process of removing the lees (dead yeasts and sediments) after bottle fermentation. Some pét-nat makers may disgorge, and others may choose not to. Pét-nats that do not go through disgorgement tend to be cloudy and funky to the nose and the palate. 

But nothing screams hipster rustic more than an unpredictable, cloudy, funky wine that is bottled and enclosed with a crown cork. 

I had the pleasure of tasting two pét-nats from Grosgrain, a Walla Walla winery. Here's what I think:

Grosgrain Pét-Nats

2020 Pétillant Naturel Sparkling Sémillon, Les Collines Vineyard, Walla Walla AVA, 11.1% alcohol

The wine is deep gold, lightly bubbly, and a little cloudy. It is definitely funky and yeasty to the nose. On the palate, it is surprisingly light, crisp, and citrus-y with a higher acidity than a still Sémillon. I would say it is somewhere between a cider and a wine. It is definitely interesting.

2020 Pétillant Naturel Sparkling Old Vine Lemberger, Kiona Vineyard, Red Mountain AVA, 12.4% alcohol

The wine is medium copper, a little frothier, and a little cloudier. The nose is pleasantly floral and fruit-forward without any yeasty funk. It continues to delight on the palate with bright fruit and high acidity. There is still the hint of a cider characteristic. It is my favorite between the two.

My Verdict: I definitely enjoyed trying the pét-nats. It will probably not replace Champagne as a celebratory special-occasion wine, but I can see pét-nats in the rotation at a summer barbecue. What do you think?

Sulfites Problems and The Magic Wand

Recently I had a few problems with sulfites in my wine. It is not what you think. In fact, it is probably the opposite of what you think. I forgot to add sulfites to my wine. I'll get into that in a minute. But first let's talk about more commonly known problems with sulfites - real and perceived.

Real Problem

Sulfites are naturally occurring compounds found in wine and other food sources such as peanuts, eggs, and tea. Because sulfites are also antioxidants, they are often added as preservatives to slow down browning or discoloration of food. 

In the 1970s as salad bars gained popularity in the United States, there was a dramatic uptick in the use of sulfites to keep the fruits and vegetables "fresh." With that came a rise in the cases of severe sulfite reactions. Sulfite sensitivity manifests in asthmatic symptoms such as wheezing and in rare cases anaphylactic reactions. Some people develop hives, swelling, or stomach pain. 

In 1986, the Food and Drug Administration (FDA) banned the use of sulfites in salad bars as a response to the increase in cases of sulfite allergy and sensitivity. It is estimated that about 1% of the population is sensitive to sulfites, and those with asthma are more susceptible.

Perceived Problem

Contrary to popular belief, headache is not a typical reaction to sulfites. But because many people suffer headaches from wine consumption, sulfites have become the easy target. In reality, wine-induced headaches are more likely due to dehydration from alcohol consumption or from the histamines and other compounds in wine. 

Wine wands

That said, the market wastes no time in capitalizing on the perceived problem of sulfites by offering a multitude of solutions, from sulfite-free wines to sulfite-removing wands, filters, and drops. While these may be effective in removing sulfites, one wonders if they eliminate wine-induced headaches or hangover since there is no scientific evidence that sulfites are the cause. There is however no accounting for the placebo effect.

Too Little Sulfites

The addition of sulfites during winemaking is necessary for the production of high-quality wine. Winemakers often pitch potassium metabisulfites into the wine post-fermentation to protect it from spoilage. When sulfites come into contact with the water in the wine, sulfur dioxide (SO2) is released. A portion of the SO2 will immediately bind with certain chemicals in the wine while the remainder will be in a free state (FSO2) to take on harmful microorganisms and to slow down premature aging of the wine.

My first problem for my 2020 vintage is that I forgot my post-fermentation sulfites. While the science behind how much and when to add sulfites is complex and entails conducting multiple tests, a good rule of thumb for hobby winemakers is to pitch a certain amount every month to ensure adequate protection of the wine. And I did none of that this past vintage.

It was not till I ran a pre-bottling panel on my wine four months after fermentation that I found out that there were only 2 parts per million (ppm) of FSO2 in my wine. That is winemaker's talk for virtually zero protection for my wine from spoilage. 

Using the pandemic analogy, it is like going to a store without the protection of a mask or vaccination and hoping not to catch COVID. Thankfully, the wine was still tasting fine.

Too Much Sulfites

In my moment of panic, I googled the first website that gave me the target FSO2 level based on my wine pH. I did a quick calculation and pitched the sulfites as quickly as I could. Then I found a couple more websites that suggested target FSO2 levels that were significantly lower than the first website. One of the later websites had a target FSO2 level that was half of what I had pitched.

Great! Now a giant sulfite-removing magic wand doesn't sound so bad.

The truth is that it is hard to determine the right level of FSO2. Each wine's chemical makeup presents numerous variables that may bind with the sulfites, making it hard to determine how much FSO2 is left without running yet another test. Too much sulfites will inhibit the wine's ability to develop in complexity and give the wine a chemically metallic taste. Too little sulfites will increase the chance of spoilage. The winemaker treads lightly between the two.

Using the pandemic analogy again, it is like wearing five masks to the store which may protect you from COVID, but you may not be able to breathe.


Wine racking

Since I don't have a giant magic sulfite-removing wand, I decided my best recourse is to rack the wine despite mixed reviews with this approach. Put simply, wine racking is siphoning wine from one vessel to another, a process that introduces oxygen that will hopefully bind with excess sulfites. 

My Verdict: This is my fifth vintage. With every vintage, you learn something new that will help you improve your winemaking skills for the next vintage. There is no magic wand in that. I will let you know in 6 to 12 months how the vintage tastes.

Oh No! My Wine is Dumb!

Recently I opened a bottle of my 2019 Syrah, excited to taste my latest vintage. I poured it into a glass and admired the beautiful dark inky red.

I swirled the glass and took a whiff. 

Nothing

I took a sip. 

Nothing

I panicked, stuck an aerator on the bottle, and aerated the wine as I poured, something I rarely did as I preferred swirling. 

Nothing.

I grabbed a couple of truffle salt potato chips and started chomping. Yup, I could definitely taste that. After ruling out COVID since I am fully vaccinated after all, I came to the dreaded realization that my wine was in a dumb phase.

Dumb Phase - An Anomaly?

The dumb phase of a wine describes a period of time where the aromas and flavors are shut down, often temporarily. The science behind the dumb phase is fuzzy, and therefore, it is hard to predict when a wine may get in or (if we are lucky) out of a dumb phase. The collective winemakers' experience and anecdotal evidence provide some guidance on how to mitigate this unfortunate phenomenon. But first, let's dip our toes into the science behind wine evolution. 

Wine is an organically complex product. It contains phenolic compounds that are extracted primarily from the grapes during the fermentation process. In red wine, these compounds come from grape skins, seeds, pulps, and stems. The phenolic compounds include pigments, flavonoids, tannins, and such to give the wine its unique combination of color, aroma, taste, mouthfeel, and structure. 

Wine science by Vladimir Fedotov on Unsplash

Over time, these phenolic compounds will react with one another, causing the wine to evolve. A young wine is often vibrant in color, fruit-forward in aroma and taste, with pronounced and astringent tannins. As wine ages, the pigments known as anthocyanins bind with tannins and other compounds to form polymeric pigments. The various chemical reactions result in a wine with a more orange-brown hue, softer astringency, and finer tannins. If high-quality grapes, barrels, and winemaking practices are involved, a mature wine will likely develop in complexity with secondary and tertiary flavors.

Disruption or Development?

It is hypothesized that the dumb phase may be due to the disruption of the chemical reactions among the phenolic compounds, leaving them disjointed and shutting down the wine expression. At the same time, it could also be part of the natural development or evolution of certain wines. Let's delve more into this paradox.

1) Bottle Shock

The earliest occurrence of a dumb phase is when the wine is newly bottled. This is also known as bottle shock. The theories behind its cause are all related to the bottling process. The amount of splashing that takes place during bottling may introduce too much oxygen and may also cause the phenolic compounds to be shaken up, disrupting the natural wine maturation process. Or perhaps, a heavy hand with pre-bottling addition of sulfur dioxide as an antioxidant and stabilizer for the wine may remove too much oxygen, which is needed for wine maturation. This may cause the wine to be reticent till the sulfur dioxide dissipates over time.

To overcome bottle shock, many producers wait at least a year of bottle aging before releasing the wine. During the time, the winemakers may do random sampling to check on the wine.

2) Travel Shock

Similar but not identical to bottle shock, the dumb phase induced by travel shock is attributed to the wine that has recently been in transit. It is believed that a good jostling in a delivery truck, a train, a cargo ship, or even a plane plus potential temperature change during transit may destabilize the phenolic compounds causing the muted aroma and flavor.

To avoid travel shock, wine shops often wait at least one to two weeks post-transit before putting those bottles on the shelf. Some wineries that direct ship wine to their consumers recommend a wait time of up to eight weeks before opening the bottle.

3) Metamorphosis

There is no special name for the third dumb phase so I call it the metamorphosis. This is the most unpredictable and elusive of the them all as it has nothing to do with man-made jostling of the phenolic compounds in the wine. The metamorphosis dumb phase is the muted period when a wine transforms from its youthful fruit-forward vibrance to complex elegance with secondary and tertiary flavors of leather, earth, and spices. It is like the chrysalis that was once a caterpillar before it turns into a butterfly.

Wine cellaring by Reagan M. on Unsplash

There is not a whole lot one can do with this dumb phase. It seems to happen more frequently with cellar-worthy wines, such as Cabernet Sauvignon, Pinot Noir, Nebbiolo, and Syrah. Some wine collectors expect this dumb phase to happen. They would often buy a case of the same vintage, taste them through the years, and share notes with other wine connoisseurs, hoping to catch the butterfly after the chrysalis. The other option is to invest in a Coravin so that you are able to sample the wine without opening the bottle till you get to the other side of the metamorphosis.

Back to My Dumb Wine

That takes me back to my dumb wine. Normally, I open my wine at least six months post bottling, and I had not encountered a problem previously. This particular vintage was bottled nine months ago, albeit with a pretty heavy hand of sulfur dioxide to deal with a higher level of volatile acidity. It is likely that my wine was still in a bottle shock as a result of that. 

My only recourse is to wait a couple more months and try it again, probably with a Coravin this time. Wish me luck! I hope my wine wakes up by then!

Cheers to Sunshine!

Sunshine!

The long overdue reprieve from the dreary darkness of winter is finally here. As daylight stretches on and lingers, nature is bursting with life once again. Farmers markets are brimming with seasonal produce to inspire the everyday chef. My wine palate is transitioning accordingly from bold tannic leathery reds to something lighter, brighter, and crisper. 

Cherry blossoms, a sign of new life 

So join me and bask in the sunshine with something white and something pink.

Something White

Sauvignon Blanc is one of my go-to whites in the sunshine. I love the grassy, citrusy flavor with juicy acidity and a touch of minerality. 

2018 CADE Sauvignon Blanc

I generally seek out French Sauvignon Blanc in single-variety Sancerre or in a white Bordeaux blend, preferably lighter on the Sémillon. From the New World, I love a good New Zealand Sauvignon Blanc, enough to forgive the screw cap. 

More recently, I was excited to receive a bottle of CADE Sauvignon Blanc. The Napa Valley white went through a fascinating fermentation process that included 12 different strains of yeast in a combination of stainless steel, oak (new and used), and concrete vessels. It is then aged on the lees in stainless steel and oak for five months. The end result is a quintessential Sauvignon Blanc with a lot of complexity and textural interests.

2018 CADE Sauvignon Blanc

  • Color - Light pale straw with great clarity
  • Aroma - Fragrant with apple and grapefruit 
  • Taste - Lively and crisp, tart green apple, honey, and salty minerality
  • Acidity - Bright and gripping acidity
  • Body - Medium-plus body, coating the mouth and luscious
  • Finish - Lingering
Food Pairing: Indian spiced rice, samosas, dollops of cilantro chutney, over a pile of romaine lettuce, cherry tomatoes, sweet onion slices, and chunks of avocado.

Spiced rice, samosa, cilantro chutney, avocado

Something Pink

Pink wine runs the gamut from light to hearty in flavor and almost correspondingly from pale salmon to deep pink in color. My favorite is the Provençal rosé, which lands on the more delicate end of the spectrum.

2020 The Walls Cruel Summer Rose
There is an air of romance about Provençal rosés. Perhaps it is the pale blush hue or the floral scent that reminds one of lavender fields. The French pink wine is made with predominantly Grenache grapes. It is everything I love about fresh citrusy white wines plus the bonus red fruilt flavor and pink tinge coaxed briefly from the grape skin.

On this side of the Atlantic, you can find well-made Provençal-style rosés as well. The Walls' Cruel Summer is one such rosé, made with 80% Grenache and 20% Mourvèdre. It was a fun wine, fresh, interesting, and delightful! 

2020 The Walls Cruel Summer Rose

  • Color - Pale salmon
  • Aroma - Highly scented with apple and honeysuckle
  • Taste - Fresh and vibrant, tart green apple, juicy minerality
  • Acidity - High racy acidity
  • Body - Medium-plus body, elegant and silky
  • Finish - Lingering
Food Pairing: Bruschetta, crostini smeared with pureed English pea, basil, mint and EVOO, topped with crumbled feta.

English pea bruschetta

So as the weather permits and al fresco dining is in the plan, what is your wine pick to toast to the sunshine? I hope it is something light and crisp, maybe something white or pink.

More Than Grape Skin Deep

Many people think of wine as red or white. Red wine comes from red grapes, and white wine comes from white grapes. While generally true, the pantone palettes of grape colors run the gamut of yellow, green, pink, purple, and even black. Still, the beauty of wine is more than grape skin deep. Let's explore a little more together. 

Wine colors by Maksym Kaharlytskyi on Unsplash

Red Wine

Red grape skin contains anthocyanins, water-soluble pigments, that give the fruit its color. When making red wine, the berries are often crushed lightly and left to soak in the juice, also known as the must. During this process of maceration, the grape skins, flesh, and seeds gently break down, releasing tannins, aroma precursors, and anthocyanins into the must. 

In red winemaking, maceration can happen before and during the alcoholic or primary fermentation. In fact, the winemaker is constantly balancing color, aroma, flavor, and the amount of tannins extracted from the grapes, lengthening or shortening the maceration period as appropriate.

Maceration
Once the yeast has converted all the sugar in the grapes to alcohol, primary fermentation is deemed complete. The wine is then pressed to remove all grape debris. The day before press, lactic acid bacteria is often pitched into the wine to start a secondary fermentation. In this fermentation, harsh green apple-y malic acid is converted to softer creamier lactic acid to give the wine a fuller mouthfeel.

After malolactic fermentation is complete, the wine is then left to age, usually in oak, for as long as the winemaker pleases before bottling. And that completes the process of red winemaking.

White Wine

While not obvious to the naked eye, anthocyanins are also present in the skin of white grapes. The amount is significantly lower to be detected visibly.

Unlike red wine, white wine is made with nearly no skin contact. Most of the flavor and aroma compounds in white grapes come from the pulp and not the skin. The skin of white grapes adds bitterness and astringency, both of which are undesirable for white wine.

White grapes harvest by Thomas Schaefer on Unsplash

In white winemaking, the grapes are harvested and immediately pressed. The skin is removed, and there is no maceration. Once the the clear juice is extracted, the must is inoculated with yeast, which begins the alcoholic fermentation.

After alcoholic fermentation is complete, depending on the grape variety and the winemaker, the wine may or may not go through malolactic fermentation and then aged in oak, stainless steel or concrete. White wine that has been aged in oak will have a deeper yellow shade to it. Otherwise, it is lightly-colored and crisp.

Pink Wine

Now that we have gone through the difference between red and white winemaking. Let's have some fun and mix it up. What if we use red grapes and make wine via the white winemaking method? 

Hey Presto! Pink wine!

Contrary to popular belief, pink wine or rosé is not made by mixing red wine and white wine together. The exception would be the blending of red and white still wines to be the base for the second (not secondary) fermentation of a pink sparkling wine.

Pink wine or rosé, a sign of summer

Pink wine is made when red grapes go through a very short period of maceration, usually four to forty-eight hours, before being pressed. After the grape skin and other debris are removed, the must is inoculated with yeast, and alcoholic fermentation begins the same way it does for a white wine.

The short maceration gives rosé its blush hue, which is what the English call the wine. Rosé has the flavor profile of a light red wine with a lot of red fruits. However, it is also crisp and bright like a white wine.

Orange Wine

Let's then try the reverse and use white grapes to make wine in the red winemaking method. Instead of removing skin contact upon harvest, macerate the white grapes in the must like you would for red winemaking. 

Viola! You get an orange wine!

Orange wine
While it may seem like a fad, the origin of orange wine goes back 5,000 years in Caucasus. Today, you can still find orange wine in the Republic of Georgia as well as Slovenia and Italy. 

Because the wine is made from white grapes with extended skin contact, it has the aroma of honey and ripe fruit, that is reminiscent of an oxidative wine. But on the palate, it is dry, tannic and tart like a red wine. Orange wine is like a heftier white wine that is served cool but not chilled. When well made, it is super interesting and can take on bold-flavored dishes, like curry or even lamb.

My Verdict: As you see, the color of wine is really more than grape skin deep. So why limit yourself to red and white? Try something different, something new, and let me know what you think.
