What Exactly Is a Pét-Nat?



Pét-nat is an abbreviation for “pétillant naturel”—a French term that roughly translates to “naturally sparkling.”

Maybe you already knew that. After all, pét-nat has been hip for a few years now; all the cool kids are drinking it. But even if you’ve sampled a few bottles of the stuff, you’d be forgiven for not knowing exactly what qualifies as pét-nat, or how these sparkling wines differ from other types of bubbly.

How Pét-Nats Are Made

“Pét-nat is a wilder version of a sparkling wine like Champagne,” says Jared Brandt, owner of Berkeley, California’s Donkey & Goat Winery, which has produced pét-nat since 2010. “When people ask, I tell them pét-nat is a wine that we bottle during initial fermentation, and the sugars from the grapes provide the bubbles.”

As you may know, during alcohol fermentation, yeasts eat sugar. The byproducts of this process are alcohol and carbon dioxide. In non-sparkling wines—your Chardonnays, Pinot Noirs, etc.—most or all fermentation occurs before bottling, and so there is no trapped C02, and therefore no bubbles.

Pét-Nat vs. Champagne

Traditional Champagne (and other sparkling wines like Crémant and Cava) are made by combining one or more still dry wines—basically, finished wines that have already undergone fermentation—with a small amount of yeast and sugary liqueur. This combination is bottled and aged, and the yeast eats the sugar in the liqueur. This second, in-bottle fermentation produces the trapped carbon dioxide that gives these sparkling wines their bubbles. (Prosecco and other less-expensive sparkling wines often undergo secondary fermentation in large tanks, rather than in bottles. In some cases, C02 is simply pumped into a finished wine before bottling.)

“Pét-Nat is like a junior version of this really complicated Champagne process,” says Steve Hall, co-owner of Spencer, a restaurant and natural-wine shop in Ann Arbor, Michigan. Rather than blending different dry wines and putting them through a second round of fermentation and aging, pét-nat is bottled while still undergoing its first round of fermentation. The French call this process “methode ancestral,” and it’s likely been around far longer than other, more complex methods of producing sparkling wine.

That’s not the only difference between pét-nat and traditional bubbly. While classic sparkling wines are typically made from a narrow range of grapes, Hall says winemakers today are making pét-nat with all kinds of unusual and interesting grape combinations. “People from a lot of different [winemaking] regions are experimenting with these cool sparkling projects,” he says.

Compared to Champagne and other sparkling wines, Brandt says pét-nat is unpredictable. “We have no control once it’s in the bottle, so every bottle will be a little different,” he says. When a pét-nat is first released, he says it may still be a tad sweet—the result of some residual sugar that hasn’t yet undergone fermentation. “It tends to get drier [as time passes], and to speed that up you can put a bottle in a sunny window for a few days.” (The sunlight helps encourage the in-bottle fermentation.) He also says that a pét-nat’s bubbles often become softer and smaller as it ages. But pét-nats aren’t meant for long cellaring. “I generally suggest that people drink them within three months of buying,” he says.

Pairing Pét-Nats

Asked when and how to serve them, Hall says pét-nat tends to be a fun, versatile food wine. “I think all sparkling wines go surprisingly well with food, especially lighter dishes,” he says. “Pét-nat doesn’t have the same refinement or delicacy as Champagne, but they also don’t break the bank the way Champagne does.” He says most pét-nats tend to be fairly low in alcohol—usually well under 13% ABV— and so they’re usually refreshing and great for afternoon or evening drinking. Many are also unfined and unfiltered, and may include some leftover yeast cells, which can lead to a slightly cloudy or hazy appearance. (All this is fine to drink.)

How You Know It's a Pét-Nat

Identifying them can be a little tricky. While some producers helpfully put “pét-nat” or “pétillant naturel” right on the label, others don’t. They may also use terms like “bottle fermented,” “methode ancestral,” or, if Italian, “col fondo,” which is basically pét-nat Prosecco. “If you see sediment and a crown cap”—meaning the kind of top on an old Coke bottle—“it’s probably pét-nat,” Brandt offers. Ask your friendly wine shop owner to point you in the right direction.
