Tepache de Piña (Mexican Fermented Pineapple Drink) Recipe | Kitchenstagram
Tepache de Piña is a fizzy, lightly fermented drink crafted from pineapple skins, cores and sugar. Popular throughout Mexico, it’s a centuries old beverage that feels remarkably modern in its zero-waste philosophy, refreshing taste, and probiotic benefits. Though commonly made with pineapple today, its roots go back to indigenous corn-based preparations that predate the arrival of pineapple in the region.
The term “tepache” has origins in the Nahuatl language, with “tepiātl” once referring to a corn drink. Originally, it was a fermented maize-based drink, an everyday refreshment made by the Nahua people of central Mexico. But as pineapples made their way from South America-where they are native-to Central Mexico via trade routes, local communities began incorporating the juicy fruit into the preparation. The natural sweetness and wild yeast on pineapple skin made it an ideal replacement for corn. Eventually pineapple replaced maize altogether, giving rise to the modern version of tepache.
The beauty of tepache lies not only in its flavour but in its sustainable preparation. Instead of discarding the pineapple rind and core- parts that usually end up in compost or trash, you can use them to make something vibrant and delicious. The process also mirrors other traditional fermented beverage around the world, such as kombucha or kvass, which use natural yeasts and minimal ingredients to produce complex, lightly effervescent drinks.
At its heart, tepache is incredibly simple to make. The basic recipe includes just pineapple peels and core, piloncillo or raw brown sugar and water. Over time the sugars feed naturally occurring wild yeasts and bacteria, initiating a fermentation process. This process not only creates a gentle fizz and a tangy taste, but also introduces probiotics and beneficial acids to the drink.
In terms of production, successful fermentation relies on a few important practices, using a very ripe pineapple enhances both the sugar content and the microbial diversity on the peel, which helps jump-start fermentation. It’s also crucial to use filtered or dechlorinated water, since chlorine in tap water can inhibit yeast and bacteria. Additionally, piloncillo or raw cane sugar is preferred over refined white sugar, as it adds richness and helps promote a healthy ferment.
The fermentation typically lasts between one and four days, depending on the surrounding temperature, sugar content and personal preference. Warmer temperatures speed up fermentation, making it important to monitor closely to avoid over fermenting, which can make the drink too sour or too alcoholic. Typically tepache has a low alcohol content, ranging from 0.5%-3% ABV (Alcohol By Volume). The exact alcohol percentage can vary based on fermentation time, temperature and the amount of sugar used.
Microbiologically, tepache is fascinating. The drink typically contains various species of lactic acid bacteria (like Lactobacillus plantarum, L. Paracasei, and L. Lactis) as well as wild yeasts such as Saccharomyces cerevisiae. These microorganisms interact in complex ways: the yeasts convert sugars into alcohol and carbon dioxide, creating bubbles and that characteristic fizz, while the bacteria produce lactic acid, giving the drink its refreshing tang.
During fermentation, you might notice a thin, creamy-white layer forming on the surface. This is known as kahm yeast- a harmless aerobic yeast that thrives in exposed ferments. While it doesn’t pose a health risk, it can sometimes impart an off-flavour if allowed to grow too thick. You can either gently skim it off or stir it back in during early stages. However, if you see any fuzzy mold in shade of blue, green or black, it’s best to discard the batch entirely, as that indicates spoilage.
Making tepache at home is rewarding, forgiving and surprisingly quick. The method is as straightforward as it is satisfying, simply add pineapple scraps and sugar to water in a large jar, cover with a breathable cloth and let nature take its course. Within a few days, the mixture will begin to bubble as fermentation kicks in a quick strain and chill later and you’ll rewarded with a tangy, sparking drink that’s unlike anything you’ll find in a can or bottle.
Beyond its taste and practicality, tepache carries cultural significance. It reflects Mexico’s long-standing traditions of fermentation, sustainability and celebration of local ingredients. Even today, it remains a staple at family gatherings, street markets and even high-end restaurants experimenting with artisanal ferments.
Still, there’s something extra satisfying about brewing it yourself. Not only do you reduce food waste, but you gain an appreciation for the rhythms or fermentation and the power of natural ingredients. It’s a humble process, but one that feels alchemical, turning discarded scraps into something bubbly, nuanced and vibrant.
What sets tepache apart is its unique blend of tropical fruitiness, mild tartness and earthy depth. While it’s often left unflavoured, some regional versions include additions like cinnamon sticks, cloves or chili powder for extra complexity. In street markets throughout Mexico, it’s commonly ladled from large wooden barrels and sold in cups or plastic bags with straws, especially welcome on hot days. Its low alcohol content and tangy sparkle make it accessible to all ages and tastes.
Ingredients needed for Tepache:
Tepache is a simple, lightly fermented drink that relies on just a few natural ingredients to create its signature tangy-sweet flavour.
Pineapple: Pineapple is the heart of tepache. The natural yeasts found on the fruit’s peel kickstart the fermentation, so there’s no need for a starter culture. Organic pineapples are preferred to avoid unwanted pesticides, but not strictly necessary. Using a very ripe pineapple yields a better brew with a stronger pineapple flavour and more sugar for the yeast and bacteria to consume and the microbial diversity on the peel, which helps jump-start fermentation.
Sugar: Sugar feeds the fermentation process. Traditionally, unrefined cane sugars like piloncillo, panela or jaggery are used to impart deep, rich notes.
Spices: I am using cinnamon sticks and fresh ginger because their spicy and warm notes pair well with the pineapple.
Water: Water acts as the fermentation base. It’s also crucial to use filtered or dechlorinated water, since chlorine in tap water can inhibit yeast and bacteria. If using tap water, it’s best to let it sit uncovered for a few hours so the chlorine dissipates as high chlorine levels can hinder fermentation and affect the final taste.
When is Tepache ready to drink:
Tepache is a fast, wild-fermented beverage and its readiness depends largely on your environment. In warm temperatures (around 70-78ºF), it usually takes about 2-3 days to reach that ideal balance of flavour. Cooler climates may stretch fermentation to 5 days or more.
You’ll know your tepache is ready when you notice a thin layer of foam forming on the surface, a gentle fizz when you stir or pour, and a tangy, sweet aroma. Taste is your best guide- it should lightly effervescent, earthy and mildly tart, with a subtle caramel finish.
There’s no exact rule, so start tasting daily after the first 48 hours. Once the flavour hits the sweet spot, not too sugary, not overly sour, it’s time to strain out the solids and refrigerate the liquid. Serve it chilled, ideally over ice.
Want a deeper funk or stronger acidity? Let it ferment an extra day or two. But don’t wait too long- tepache continues to sour, even in fridge and can eventually develop a vinegar-like edge.
Ingredients
1 no. Ripe Pineapple, washed
1/2 cup Brown Sugar
4 1/2 cup Filtered Water (non-chlorinated)
Fresh Ginger, smashed
1 no. Cinnamon Stick
Preparation
- Step 1: Cut off the crown of the ripe pineapple and discard it or the crown can be used to grow a pineapple if you plant it. Peel your pineapple and cut the pineapple lengthwise into quarters and then remove the hard center core and reserve them. Save the fruit for other use.
- Step 2: In a glass jar combine brown sugar, water, smashed ginger, cinnamon and pineapple skin and core.
- Step 3: Cover the jar with a clean cheesecloth or a clean kitchen towel and secure with a string. Store away from the direct sunlight at warm room temperature, between 70-78ºF.
- Step 4: Let stand, stirring once a day, until a thin layer of frothy white bubbles forms on the surface. If you see frothy white bubbles on top then it’s fermenting, you can let it brew for another 1-2 days. Once the frothy bubbles have formed, taste the tepache, it should have a sweet, earthy and funky flavour.
NOTE: Always place your tepache in a warmer spot. The fermentation process may take up to several days, depending on the environmental conditions and other variables.
- Step 5: When your tepache has reached desired flavour, strain through a fine-mesh strainer lined with cheesecloth in a clean bottle, discard the solids.
- Step 6: Chill your tepache before serving. Enjoy!!
Pro tips:
Don’t toss those extra pineapple scrapes! Collect enough to make a larger batch and store it in the fridge until you’re ready to ferment.
Warmer kitchens speed up fermentation, so check it daily. A slightly tangy, bubbly sip means it’s ready. Prefer a stronger kick? Let it ferment a bit longer.
Cover your jar with a breathable cloth and secure it tightly with a rubber band or string. This will keep pesky fruit flies out while allowing air to circulate.
