How to Make Tepache
Tepache is a refreshing Mexican fermented beverage made from pineapple rinds and cores, sweetened with piloncillo (raw cane sugar) and spiced with cinnamon and cloves. This mildly alcoholic, effervescent drink has a tropical, tangy-sweet flavor that's both refreshing and complex.
Category: Beverages · Method: Alcoholic/Yeast · Time: 2-5d · Difficulty: 1/5 · Yield: ~2L · Temp: 20-25°C
History
Tepache's origins trace to pre-Columbian Mexico, where indigenous peoples fermented corn and various fruits. The pineapple version became dominant after Spanish introduction of the fruit. Street vendors called 'tepacheros' have sold this drink from clay pots for centuries. It remains beloved in Mexican markets and homes as an affordable, delicious, waste-reducing beverage.
Ingredients
- 1 large Pineapple — Use rinds, cores, and some flesh - organic preferred
- 1 cone (8 oz/225g) Piloncillo — Or 1 cup brown sugar
- 1 gallon (4L) Water — Filtered, non-chlorinated
- 1 large Cinnamon stick — Mexican canela preferred
- 4-5 Whole cloves — Optional but traditional
Equipment
- Large glass or food-safe plastic container (1.5+ gallons)
- Cheesecloth or clean kitchen towel
- Rubber band or twine
- Fine mesh strainer
- Bottles for finished tepache
- Wooden spoon
Instructions
Prepare pineapple
Rinse the pineapple with cool water to remove debris while preserving the wild yeasts naturally present on the rind. Cut off the top and bottom. Slice off the rind in large pieces. Core the pineapple. Reserve the flesh for eating; use the rinds and core for the tepache. Roughly chop the core.
Time: 15 minutes
Tip: Avoid using soap or very hot water, as this can kill the wild yeast needed for fermentation. Don't peel too thin - some flesh on the rind adds flavor and sugars.
Optional second fermentation
For more carbonation, strain the tepache into pressure-rated swing-top bottles (Grolsch-style) and leave at room temperature for 12-24 hours before refrigerating. These specific bottles are designed to handle the pressure of carbonation.
Time: 12-24 hours
Tip: Always use bottles intended for fermentation to prevent glass explosions. Burp bottles periodically to check pressure, then move to the refrigerator to stop fermentation.
Fermentation Timeline
- Day 1: Start fermentation — Combine pineapple, sugar, spices, and water.
- Day 2: Bubbles begin — Surface may foam. Stir daily. Taste for progress.
- Day 3: Flavor developing — Tangy-sweet balance emerging. Decide if more time needed.
- Day 4-5: Ready — Effervescent, complex, refreshing. Strain and enjoy.
Signs of Success & Spoilage
Good signs
- Active bubbling on surface
- Cloudy, golden liquid
- Tangy-sweet pineapple aroma
- Pleasant effervescence
- Balanced sweet-sour taste
- Light alcohol warmth (0.5-2%)
Warning signs
- Mold on surface (white film is often normal yeast)
- Rotting smell
- Slimy texture
- Extremely sour (turned to vinegar)
- Off-putting flavors
Troubleshooting
- Mold on surface
- Cause: Contamination or pineapple exposed to air for too long Solution: If you see a fuzzy growth (white, green, or black), discard the entire batch immediately as mycotoxins can permeate the liquid. If it is just a flat, white, wavy film, it is likely Kahm yeast, which can be skimmed off, though it may affect flavor.
Storage
Refrigerated in sealed bottles Keeps 1-2 weeks refrigerated. Carbonation increases in sealed bottles. Burp periodically. Best consumed fresh.
