Step 1: Prep the Pineapple
Wash the pineapple thoroughly to remove dirt and pesticides.
Cut off the top and bottom and discard.
Slice the pineapple into chunks, including the skin and core, as these add flavor to the fermentation.
Step 2: Assemble Ingredients
Place the pineapple chunks into your glass or ceramic jar.
Lightly crush the cloves, allspice, and cinnamon stick in a mortar and add them to the jar.
Pour in 8 cups of water and stir well to combine.
Seal the jar tightly and place it in a warm spot with access to sunlight. Let it sit for 3 days.
Step 3: Check for Fermentation
After 3 days, check for bubbles forming on the surface. This indicates active fermentation. If bubbles haven't formed, let it ferment for another day.
In a saucepan, combine the remaining water and brown sugar. Heat until the sugar dissolves, then let it cool to room temperature.
Step 4: Add Sugar Syrup and Optional Beer
Add the cooled sugar syrup to the jar.
If you prefer a slightly alcoholic version, mix in the light beer.
Stir well, reseal the jar, and let it ferment for another 3 days.
Step 5: Strain and Serve
Once fermentation is complete, strain the mixture through cheesecloth to remove the pineapple chunks and spices.
Press the pineapple chunks to extract all the liquid.
Refrigerate the strained tepache until cold.
Serve over ice and enjoy!
