Step 1

Using the traditional big eathenware jug (or a large pot), bring to a boil the 16 cups water along with the piloncillo, cinnamon stick, and whole cloves. Simmer, stirring once in a while, for about 10 minutes or until the piloncillo has dissolved.

Step 2

While the water is simmering, wash the pineapple thoroughly, and remove the stem and bottom. Cut it into 2 inch cubes, without taking off its rind.

Step 3

Once the flavored water is ready, add in the pineapple chunks and cover. Let rest for 2 days, or 48 hours, in a warm area of you kitchen. The mixture will begin to ferment and bubble on the surface. Add a cup of lager beer, stir well, and let it sit for up to 12 hours more. Don't let it ferment much longer, or you may end up with vinegar instead!

Step 4

Strain tepache through a fine strainer or cheesecloth, and serve very cold. You can either refrigerate it or serve over ice cubes.
