Sparklers for Valentine’s Day and Super Bowl

Since the winter holidays, one doesn’t have to look far for a reason to pop open a bottle of sparkling wine. With Valentine’s Day right around the corner, there is yet another occasion for a sparkler. Let’s also not forget that Super Bowl beer bros and Swifties may enjoy some bubblies too. With that, here’s a primer on the different types of sparkling wine and my take on what to drink for the occasion.

From the Rustic Pét-Nat

Let’s start with how sparkling wine came about. Wine is produced from the alcoholic fermentation of grapes or grape juice (called the must). During the process, yeast in the must converts sugar into alcohol and produces carbon dioxide as a byproduct. When making a still (as opposed to a sparkling) wine, the yeast will consume virtually all the sugar and release carbon dioxide into the atmosphere. When that happens, fermentation is considered complete. The wine is then racked to remove grape debris and remaining yeast (called the lees) and bottled.

If residual sugar is left in the wine and the lees are not thoroughly removed prior to bottling, then fermentation may continue in the bottle. Carbon dioxide that is released in the process is then trapped in the bottle, resulting in a bubbly. This was probably how sparkling wine was first discovered, and the process is known as the ancestral method or méthode ancestrale. This class of sparkling wine is called pétillant-naturel or pét-nat for short.


I have made pét-nat before, and it is a really fun wine. (My friend in the video was opening a bottle of my pét-nat.) While it may be the father of all sparkling wines, pét-nat has only returned into vogue in recent years. This, not surprisingly, coincides with the natural wine movement. Unconstrained by conventions and rules, the lightly fizzy wine may be made with any grape varieties and may be filtered or not. The main requirement is that the wine is made in a single fermentation that lasts through the bottle. Many pét-nats have playful labels and are sometimes enclosed with a crown cork, like a beer bottle.

Best for Super Bowl party or any casual get-together with pub grub. A little lower in alcohol content (around 10-12% ABV) and with a friendly price point (around $20/bottle), pét-nats may deliver a range of fun and funky flavors depending on the grape variety and the length of lees contact. In fact, many would compare a pét-nat with a craft beer. So drink up, Super Bowl beer bros.

To the Ritzy Champagne

If pét-nat is the wine of the people, then Champagne is the wine of royalty. Besides being made in the region of Champagne, the namesake wine is also highly regulated in terms of grape varieties (primarily Chardonnay, Pinot Noir, and Pinot Meunier), viticulture practice, viniculture method, and the length of maturation on the lees; all of which run contrary to the making of a pét-nat.

Unlike pét-nat, Champagne goes through an elaborate winemaking process to deliver a floral, bready, nutty wine with a creamy and full texture, crisp acidity, and a steady stream of bubbles. The steps in making a Champagne, known as méthode Champenoise or méthode traditionalle, include:
  • First alcoholic fermentation: A still wine is first made and bottled.
  • Second (or secondary depending on your perspective) alcoholic fermentation: Add more yeast, sugar, and wine (the mixture is called liqueur de triage) in bottles of still wine.
  • Aging: The bottles are then aged for at least 15 months on the remaining lees.
  • Riddling or remuage: The bottles are placed on special wooden racks called pupitres or the machinery-equivalent at 35° angle and then gradually shaken and rotated in the rack at an increasing angle.
  • Dégorgement: When the bottles are virtually upside down, the remaining lees that have now settled in the bottleneck will then be frozen and removed.
  • Final Touch: The bottles are then topped up with base wine, sucrose, and sulfur dioxide (the mixture is called liqueur d’expédition) to balance and stabilize the wine before being secured with a cork and a wire cage (muselet). The amount of sweetness added is also known as the dosage.
Riddling
Best for Valentine’s Day or any special occasion. Champagne, the gold standard for sparkling wine, can be a splurge with a starting price of $50/bottle. However, the sparkler is super versatile and can pair with a wide range of cuisine from fried chicken to fresh oysters. But nothing says luxury better than Champagne and caviar.

And Everywhere in Between

Traditional Method, but not Champagne - Do you like a Champagne but not the price? Thankfully, there are many wallet-friendly bubblies available outside of Champagne that are made in the traditional method. These include French crémant, Spanish cava, and sparkling wines all over the world with Traditional or Champagne Method stated on the label.

There are eight French crémant regions, each with its own regulations around grape varieties and style. The same goes to Spanish cava. However, these regulations are less stringent than those in Champagne, allowing the producers to keep the cost down while delivering quality sparklers.


While New World bubbly producers are not restricted in how they make their wine, they tend to go beyond méthode Champenoise. This includes the use of Chardonnay, Pinot Noir, and sometimes Pinot Meunier grapes. Many even follow the Champagne labelling of Blanc de Blanc (100% Chardonnay) and Blanc de Noir (100% Pinot Noir clear juice) in their offerings.

Best for a Valentine’s Day celebration on a budget or casual brunch. The price range varies, but a bottle of Cava may start with $10/bottle. At that price, you can even use it to make mimosa or Champagne float guilt-free. (Side note - Please do not use real Champagne in your Champagne float.)

Charmat Method - If you remove the labor-intensive steps of second (or secondary) fermentation in the bottle as well as the subsequent riddling and dégorgement, you may end up with the Charmat method. In this method, the liquer de triage is added to still wine in a pressurized tank instead of a bottle. The wine then goes through second fermentation is in the tank for 1 to 6 weeks. After this, the wine is clarified, and dosage is added during bottling.

While commonly known by its French name, the Charmat Method was invented and patented in 1895 by Italian winemaker in Asti named Federico Martinotti. A couple of decades after that, French oenologist Eugène Charmat improved on the process and patented it. In Italy, this process is sometimes known as the Martinotti method.

In terms of flavor profile, bubbly made in the Charmat method tends to be more aromatic (mostly due to the grape varieties used) but lacks the nutty, bready, multi-dimensional flavor found in Champagne. As one might expect given its origin, many Italian sparklers are made in the Charmat method; the most famous of which is Prosecco. This low-labor low-cost approach is also adopted around the world. If the label on a New World sparkling wine does not indicate the traditional method, it is probably made using the Charmat method.

Best for Super Bowl party, a casual get-together, or brunch. Starting at a price of less than $10/bottle, sparkling wine made in the Charmat method can be enjoyed as-is or be used to make fun sparkling cocktails. Peach Bellini, my Swiftie friends?

Now that you know about the different types of sparkling wine, what will be your pick for Valentine’s Day or Super Bowl party? I’d love to hear what you think.

Que Syrah, Syrah, Syrah

Perhaps it was the pandemic. Or perhaps I had been in a winemaking rut. Nonetheless I decided to shake things up this year. The outcome? From a single Syrah grape variety, I ended up with three wines: a red, a rosé, and a pétillant-naturel (also known as pét-nat). Let me share my journey.

One grape, three wines

An Order of Doble Pasta Please!

After making only red wine for the past five years (along with all the rookie mistakes), I wanted to experiment with doble pasta to give my wine more concentrated flavors and depth. Far from the carb-laden name, doble pasta is really a winemaking technique where the crushed grapes are fermented with extra skins and pulp to extract a higher intensity of flavors, color, and tannins.  

Hailed from Spain, doble pasta is practiced in the southeastern wine regions of Alicante, Jumilla, Utiel-Requeña, and Yecla. There, the crushed grapes are traditionally macerated with twice the amount of grape skins and pulp, hence the word doble, while retaining the same amount of juice. 

Free run juice from half the grapes

My Syrah grapes arrived in mid September, freshly harvested from the vineyard that morning. After the grapes had been de-stemmed and macerated for a couple of hours, I put half the grapes into the basket press and let gravity draw out the free-run juice. I was careful to retain the tannins, anthocyanins, and other flavonoids in the skins and pulp to be added to my other half of the grapes that were macerating in a separate fermenter. My own doble pasta!

It would appear that doble pasta also meant doble cap. Cap refers to the crushed grapes that rise to the top of the juice during alcoholic fermentation. Typically, the winemaker punches the cap down into the juice two to three times a day to extract flavors and prevent bacterial activities. With twice the cap mass, this proved to be quite the workout. I ditched my regular metal paddle and went for a glass gallon jar for punchdown. A genius move if I may say so myself. Even then, the cap was so thick that the gallon jar could just sit on it.

I also learned that doble pasta also meant more grapes to break down and more sugar to convert to alcohol. I had not accounted for that when I measured out the amount of yeast to use. As a consequence, my red was fermenting several days longer than normal. However, the reward was a rich wine with concentrated flavors. I am excited to see how the wine will further evolve with malolactic fermentation and oak maturation.

No Way, Rosé!

Not to waste the free-run juice, I used it to make my very first rosé. First I watered back the juice to reduce the Brix (or sugar content) to keep the wine at a lower alcohol level. Plus, I wanted to lighten the color but was barely successful as Syrah is a highly pigmented variety. As fermentation went on, the difference in colors for both wines was astounding. The rosé developed a deep pink hue, while the red was inky and dark.

Rosé is made when you ferment red grapes using white winemaking method. It starts with separating the skins and pulp from the juice, which I did as part of doble pasta. I then used a white wine yeast strain known for producing crisp aromatic wine with intense fruit flavors. Like making a white wine, rosé is also fermented at a lower temperature (60°F) than that for a red wine (80°F).

As one might expect, more rookie mistakes were made in the making of the pink wine. Rosé is fermented in a carboy with an airlock to limit exposure to air. At the same time, adequate headspace is needed for the release of carbon dioxide from yeast activity. Getting the right amount of headspace, however, takes some trial and error, and in my case, a rosé eruption (see video below).

Because of the cooler temperature, rosé fermentation could go on for a while. Even with a zero Brix reading on the hydrometer, my rosé continued to bubble, an indication of ongoing yeast activity. I let it go for a few more days before the bubbling slowed down. After which, I racked the wine and topped it up, this time to truly minimize headspace. Sulfur dioxide was then added to inhibit further fermentation, and then the wine was chilled at 50°F to settle out any tartrate crystals (also known as wine diamonds). After a month in the fridge, the wine was finished and bottled. Viola!

What? A Pét-Nat?

While the rosé was bubbling with a zero Brix reading, I had a taste of the wine and really liked it. The thought of ditching the still rosé and bottling the lightly fizzy wine as a pét-nat crossed my mind. Pét-nat is after all a wine that has not completed fermentation, which is exactly what was going on.

That temptation was quickly killed by my fear of glass bottle explosion. That is always a risk when making a pressurized beverage. Being new and ill-equipped to accurately measure the dissolved carbon dioxide and its subsequent pressure in a glass bottle, it seemed prudent to keep the experiment limited. Besides, why choose one over the other when you can have both (or all three if you include the red)? 

Pét-nat securely stored in a bucket

So I decided to siphon out enough fizzy rosé to fill two previously used beer bottles. That would suffice as my little experiment. I then enclosed the bottles with crown corks, which is very hipster-y, and stored them in bucket with the lid on in case of a bottle explosion.

Que Syrah, Syrah, Syrah

It has been two and a half months since harvest. The pét-nat was the first to be bottled towards the end of September. The rosé followed suit after a month. The red is still in malolactic fermentation, a process often skipped when making white and pink wines. Since the proof of the wine is in the tasting, here are my notes of the three Syrahs as tasted this past Thanksgiving:

Pét-Nat: Foamed over after uncorking as pét-nats sometimes do. Deep pink and hazy. Highly aromatic with pressed sugarcane, cherry, apple cider, and a touch of brioche. Subtle fizz but not sustained. Medium body, dry, and very refreshing with a slight funk. Not bad for a first try!

Rosé: Deep pink in color but clear. Aromatic with rich cherry flavor and a tinge of sweetness. Medium body but refreshing with a lingering finish. Not quite the Bandol rosé, but a wonderful pairing with roast turkey and Thanksgiving sides.

Red (Barrel Tasting): Deep purple in color. Aromatic with cherry Jolly Rancher and white pepper. Full body. Medium plus acidity, a little astringent indicating that malolactic fermentation is not complete. Fine tannins and lingering finish.

My Verdict: Making three wines from a single grape has been a fun experiment and a much needed fresh breath of air. Now which wine shall I pick to drink to your good health this holiday season? Que Syrah, Syrah, Syrah. Whatever will be, will be, will be.

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.

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?
