In this FAQ, we answer common questions about pet-nat, from how it's made to how to serve it. Whether you're a natural wine newbie or a seasoned enthusiast, you'll find practical tips to help you pick a bottle that suits your taste.

What Does 'Pet-Nat' Mean?

Pet-nat is a nickname for pétillant naturel, a French term meaning 'naturally sparkling.' It refers to a method of making sparkling wine where the wine is bottled while it is still fermenting. The fermentation continues in the bottle, trapping carbon dioxide and creating bubbles. This technique is also known as 'méthode ancestrale' and predates the more complex Champagne method.

Because the process is simple and hands-off, pet-nats often have a slightly cloudy appearance and a rustic character. They are typically lower in alcohol than other sparkling wines and can range from bone dry to slightly sweet. The flavor profile varies widely, from bright and fruity to funky and earthy, depending on the grapes and winemaking choices.

How Is Pet-Nat Different from Champagne?

Champagne is made using the 'méthode traditionnelle,' which involves a secondary fermentation in the bottle after the wine is blended. This process requires precise dosages, aging on lees, and riddling to remove sediment. Pet-nat, on the other hand, undergoes a single fermentation that starts in the tank and finishes in the bottle. It's a more natural and less manipulated approach.

Because pet-nat is often made with minimal intervention, it can be unpredictable. You might find a pet-nat that's slightly fizzy or one that's fully sparkling. The flavor is often more expressive of the grape and terroir, and it's usually bottled without added sulfites or fining agents. This makes it a favorite among natural wine drinkers who appreciate authenticity over uniformity.

What Does Pet-Nat Taste Like?

Pet-nat can taste like a lot of things. Since it's made from various grapes and regions, the flavor can range from zesty and citrusy to funky and yeasty. Some pet-nats have a touch of sweetness because the fermentation stops naturally before all the sugar is converted. Others are bone dry with a tart, refreshing finish.

If you're new to pet-nat, start with a style you already like in still wines. For example, if you enjoy crisp whites, look for a pet-nat made from Chenin Blanc or Sauvignon Blanc. If you prefer reds, try a pet-nat made from Pinot Noir or Gamay. The key is to be open to the unexpected—pet-nat is all about celebrating the wine's natural character.

How Should I Serve Pet-Nat?

Pet-nat is best served chilled, between 45-50°F (7-10°C). It's a versatile wine that pairs well with a variety of foods, from appetizers and salads to fried dishes and spicy cuisine. Because it's often cloudy, don't be alarmed if you see sediment in the bottle—that's a sign of a natural wine. You can pour it carefully to avoid disturbing the sediment, or embrace it for a fuller flavor.

When opening a pet-nat, be prepared for a potential gush of bubbles. Since the fermentation continues in the bottle, there can be more pressure than expected. Chill it well and open it slowly, tilting the glass at an angle to control the flow. Once opened, pet-nat is best consumed within a day or two, as it tends to lose its fizz quickly.

Is Pet-Nat the Same as Natural Wine?

Pet-nat is often categorized as a natural wine because it's made with minimal intervention, using native yeasts and no added sulfites. However, not all natural wines are sparkling, and not all pet-nats are certified organic or biodynamic. The term 'natural wine' refers to a broader philosophy, while pet-nat is a specific production method.

If you're looking for a pet-nat that aligns with natural wine principles, look for bottles that mention organic farming or minimal intervention. For example, Jumbo Time Wines, a Los Angeles-based natural winery, focuses on farming practices and minimal cellar intervention, making their wines a good choice for those who value the natural approach.
