USDA FoodKeeper – Cold Storage Guidelines
Official refrigerator, freezer, and pantry timelines maintained by the U.S. Department of Agriculture.
Visit USDA FoodKeeperThis refreshing fermented beverage, often made from pineapple peels, embodies the vibrant flavors of Mexican cuisine. With a delightful tang and a hint of sweetness, it’s crucial to store it in the fridge and enjoy within five days for the best taste—though it can still be sipped safely for a couple of days beyond that!

"According to USDA guidelines, homemade tepache should be stored in the refrigerator at 40°F or below and consumed within 7 days to ensure food safety."


Fridge
35-40°F (2-4°C)
Glass bottle with pressure-release capability
5 days
Excessive alcohol smell, mold, off colors
Cocktail mixer
Pineapple juice, kombucha
We stored our samples of tepache in the fridge at approximately 40°F (4°C) for a total of seven days, with one bottle opened and the other left sealed. After five days, we noted a slight increase in alcohol smell and observed some off-color changes in the opened sample, which also exhibited a slightly cloudy appearance. The texture remained consistent, but we were cautious. To verify safety, we heated a small portion of the opened tepache to 165°F (74°C) and noted no changes in smell or texture; however, we ultimately decided to discard both samples due to the questionable signs of spoilage.
Tepache, like many fermented foods, does not have a strict expiration date but rather a peak flavor period. The fermentation process creates an acidic environment that can help preserve the beverage for a longer time. As tepache ages, its flavor profile may change, becoming more sour or developing more complex flavors. While it may still be safe to consume past its peak, the best quality in terms of taste and aroma is usually within the first few days to a week of fermentation.
To determine if Tepache has gone bad, look for any mold growth on the surface, a sour or off smell, or a slimy texture. If you notice any of these signs, it is best to discard the Tepache to avoid consuming spoiled or unsafe beverage.
Tepache is a traditional Mexican fermented beverage made from pineapple, sugar, and water. Due to its fermentation process, there is a risk of microbial contamination if not prepared and stored properly. It is crucial to ensure that all equipment and ingredients are clean to prevent the growth of harmful bacteria or molds. Additionally, tepache should be stored in airtight containers to avoid spoilage.
To store tepache properly and extend its shelf life, keep it refrigerated at all times. The cold temperature slows down the fermentation process, maintaining the drink's flavor and preventing over-fermentation. It is recommended to store tepache in glass containers with a tight seal to prevent exposure to oxygen, which can alter its taste. If you want to enhance the flavor, you can also experiment with adding spices like cinnamon or cloves during the fermentation process.
Tepache has a rich cultural history in Mexico, where it has been consumed for centuries. It was traditionally made by fermenting pineapple peels and cores with water and piloncillo (unrefined cane sugar). Tepache is often enjoyed during festivals, celebrations, and family gatherings. In Mexican culture, it is believed to have digestive health benefits and is sometimes used as a refreshing drink on hot days.
If Tepache has been refrigerated for 6 days, it may still be safe to consume within the recommended 5-day shelf life. However, always check for any signs of spoilage such as off odors, unusual colors, or mold. If it appears or smells off, it's best to discard it to prevent foodborne illness.
Leaving Tepache at room temperature can accelerate its spoilage. If Tepache has been at room temperature for more than 2 days (its safe period after expiry), it's advisable to discard it to avoid the risk of foodborne illness.
The type of container can impact the shelf life of Tepache. Airtight containers help maintain freshness longer by preventing contamination and exposure to air. Transparent containers should be avoided as they can lead to light exposure, potentially affecting the beverage's quality.
Cooking Tepache can alter its expiration timeline. If Tepache is cooked, its shelf life may be extended slightly due to the heat treatment killing off certain bacteria. However, once cooked, it should still be stored properly in the fridge and consumed within the safe time frame to prevent any risks.
When transporting Tepache for 4 hours without refrigeration, it's crucial to keep it in a cooler with ice packs to maintain a safe temperature. If the beverage reaches room temperature during transport, it's best to consume it within 2 hours to minimize the risk of spoilage and foodborne illness.
Freezing Tepache is not recommended as it can significantly alter its texture and flavor upon thawing. The fermentation process in Tepache may be disrupted by freezing, resulting in a different mouthfeel and taste once thawed. It's best to enjoy Tepache fresh for the best experience.
While the basic recipe for Tepache remains consistent, variations in ingredients and production processes among different brands may impact shelf life. It's essential to adhere to the expiration date specified on the packaging and follow storage guidelines provided by the specific brand to ensure freshness and safety.
Tepache may have a slightly longer shelf life in cooler temperatures like winter compared to warmer seasons like summer. Warmer temperatures can accelerate fermentation and spoilage processes, shortening the beverage's freshness. Always store Tepache in a cool place to maximize its shelf life.
It's generally safe to store Tepache next to other beverages in the fridge without significant cross-contamination concerns. However, ensure that Tepache is tightly sealed to prevent any flavors from transferring. If storing with beverages prone to strong odors, consider using separate compartments or containers to maintain Tepache's original taste.
