Tepache is a fermented beverage made from the peel and the rind of pineapples, and is sweetened either with piloncillo or brown sugar. it is very popular in Mexico and other countries alike putting their own twist to it. This can be drunk as is

Though tepache is fermented for a few days, the resulting drink does not contain much alcohol, unless you add brewer’s yeast. In fact, the longer you ferment the pineapple, the more it gets closer to vinegar. Make sure you use organic pineapples for this recipe. The fermentation process for tepache relies on the yeast that naturally lives on pineapple peels, so you’ll want to make sure your fruit doesn’t have any pesticides residues on it

When made with clean supplies and when ingredients are submerged in the liquid while fermenting, tepache is safe to drink. The sugar in the liquid prevents bacterial growth until the yeast acidifies the drink, then the low pH takes over as an antibacterial protection. If you notice any mold growing, or detect any off-flavors or smells, throw away the whole batch. Cover with a clean dish towel or a few layers of paper towels, then secure with a rubber band. This will keep out pesky gnats or flies while allowing the yeasts to have oxygen. Set somewhere dark and room temperature (ideally 75-80°F, 24-26°C), letting it ferment for 1 to 3 days.
