As an expert sommelier and brewer, I can confidently say that tepache does have a shelf life, but it can be stored for several weeks in the fridge. Like any fermented beverage, tepache is best consumed fresh to fully enjoy its flavors and aromas. However, if stored properly, it can still be enjoyed even after a few weeks.
Over time, the taste of tepache may change. The fermentation process continues even after it has been bottled or stored in the fridge. This means that the flavors will continue to develop and evolve, which can be a positive or negative aspect depending on personal preference.
In my experience, I have found that tepache tends to become less sweet and more acidic as it ages. The natural sugars in the pineapple used to make tepache are converted into alcohol and carbon dioxide during fermentation, leading to a reduction in sweetness. The acidity can also increase as the fermentation process progresses.
To ensure the longevity of your tepache, it is important to store it properly. I recommend keeping it in a sealed container in the fridge to slow down the fermentation process. This will help maintain its freshness and prevent it from spoiling. Additionally, it is important to avoid introducing any contaminants into the bottle, as this can accelerate the spoilage process.
While tepache can be stored for several weeks, I must emphasize that its taste will change over time. This is not necessarily a bad thing, as some people enjoy the complex and evolving flavors of aged tepache. However, if you prefer a fresher and sweeter taste, I would recommend consuming it within the first week or two after brewing.
Tepache does have a shelf life, but it can be stored for several weeks in the fridge. Its taste may change over time, becoming less sweet and more acidic as the fermentation process continues. It is best kept fresh, but if properly stored, it can still be enjoyed even after a few weeks. So go ahead and savor your tepache, knowing that its flavors will continue to develop and surprise you as time goes by.
