Pre-Columbian central and western Mexico — word derives from Nahuatl tepiátl; traditional production predates Spanish contact
Tepache is a mildly fermented pineapple drink made from pineapple rinds and core, piloncillo (unrefined cane sugar), cinnamon, and cloves, fermented at room temperature for 2–3 days with wild ambient yeast. The resulting drink is lightly fizzy, slightly sour, sweet, and only mildly alcoholic (1–3% ABV). It is a street drink — sold cold in plastic bags or cups at markets. Simple to make at home, it is also used as a base for cocktails with tequila or mezcal.
Sweet-sour, pineapple-tropical, spiced with cinnamon and clove — refreshing and lightly fizzy
{"Pineapple rinds and core only — the fruit flesh is too sweet and ferments too quickly","Piloncillo (not white sugar) provides unrefined molasses notes — integral to authentic flavour","Room temperature fermentation: 2–3 days at 20–25°C; refrigerator fermentation takes longer","Cinnamon and cloves are the spice base — added whole, not ground","Strain after fermentation is complete — before bottling or serving"}
{"Use the rind from an organic pineapple if possible — conventional rinds may carry pesticide residue","At day 2, taste every 12 hours to catch the optimal sweet-sour balance","Mix finished tepache with Negra Modelo beer (1:1) for a traditional tepache cerveza","Tepache is an excellent mixer with mezcal — replace ginger beer in a Mexican mule"}
{"Using fruit flesh instead of rinds — too sweet, ferments too fast, produces off flavours","White sugar substitution — loses the piloncillo character","Over-fermenting (4+ days) — becomes very sour and develops acetic acid (vinegar notes)","Not tasting during fermentation — optimal window is narrow and varies by ambient temperature"}
