Frequently Asked Questions

What's the difference between expiration and best quality dates?

Pet Nat wine, short for Pétillant Naturel, is a naturally sparkling wine that undergoes a partially fermented process, resulting in a light effervescence. Unlike traditional sparkling wines that undergo a secondary fermentation to create bubbles, Pet Nat wines are bottled before fermentation is complete, trapping carbon dioxide from the ongoing fermentation. As a result, Pet Nat wines are known for their lively and youthful character. While Pet Nat wines do not have a strict expiration date, they are best enjoyed young to preserve their fresh and vibrant flavors. As they age, Pet Nat wines may lose some of their effervescence and fruitiness, affecting their overall quality and taste.

How can I tell if Pet Nat Wine has gone bad?

To check if Pet Nat Wine has gone bad, look for any cloudiness or sediment in the bottle, which may indicate spoilage. Smell the wine for off-putting aromas such as vinegar or mustiness. Lastly, check the texture by ensuring the bubbles are lively and the wine is not flat or fizzy.

What are the food safety risks?

When it comes to Pet Nat wine, the risks of foodborne illnesses are relatively low compared to perishable food items. However, it is important to ensure that the wine is stored properly to maintain its quality and freshness. Avoid consuming Pet Nat wine that has been improperly stored or shows signs of spoilage, such as off odors, flavors, or appearance changes.

What are some pro storage tips?

To maintain the quality of Pet Nat wine, store it in a cool, dark place away from direct sunlight and temperature fluctuations. Ideally, Pet Nat wines should be stored horizontally to keep the cork moist and prevent oxidation. Once opened, Pet Nat wines should be recorked and stored in the refrigerator to preserve their effervescence and flavors for a few days. It is best to consume Pet Nat wine within a year or two of release to enjoy its fresh and lively characteristics to the fullest.

Any interesting facts about Pet Nat Wine?

They are typically unfiltered and may have a slightly cloudy appearance, adding to their artisanal appeal. In terms of cultural significance, Pet Nat wines are celebrated for their authenticity and connection to traditional winemaking practices.

Can I store Pet Nat Wine next to other beverages in the fridge?
