As with any second fermentation, there is a risk of bottles exploding, so check on your bottles regularly and move them to the refrigerator when done. Store finished tepache in a sealed container in the refrigerator for up to a year.

How long can you keep tepache?

The solid lid will keep the bubbles from escaping and allow it to get fizzy. After that extra carbonation period, store the tepache in the refrigerator until you're ready to use it. It should keep for about 2 weeks if it lasts that long. Serve poured over ice, mixed with sparkling water or as part of a cocktail.

What happens if you ferment tepache too long?

Although, if you let it ferment for too long, you'll end up with pineapple vinegar. The picture below is what it looks like on Day 1. Pineapple Tepache will become cloudy in 2-3 days and white foam will form on the surface like the picture below.
