A gallon of kombucha in days, not weeks.

Steady, optimal temperature for your recipe → supports beneficial cultures becoming established → more predictable fermentation.

Kombucha relies on a community of yeasts and bacteria: yeasts use sugars, while bacteria produce the acids that give your brew its tang. Steady, recipe-appropriate warmth supports their activity and helps your established culture build the acidic conditions that discourage many unwanted microbes.

FermentPro maintains your selected chamber temperature, giving your tea and culture a consistent brewing environment. That makes the journey from sweet tea to your preferred sweet-tart balance easier to follow and repeat.

Temperature swings outside the suitable range → stressed or slowed cultures → less predictable fermentation and increased contamination risk.

A chilly night can slow fermentation; excessive warmth can stress the culture and change the balance of its activity. The same tea and sugar may then develop a different flavor or take a different amount of time.

If acidification is delayed or the culture is disrupted, unwanted microbes may gain an opportunity to grow. FermentPro uses heating and cooling to maintain the chamber setting your recipe calls for, helping you manage the conditions around your brew.

Temperature control supports safer practice; it does not guarantee food safety. Use the required amount of acidic starter tea, clean equipment and your recipe's acidity and completion checks.

Save 89% on your everyday favorite. The FermentPro Recipe Book estimates $0.21 in homemade ingredients versus $1.88 store-bought per 8 oz glass. That is $1.67 saved per 8 oz glass.

Enjoy one 8 oz glass a day? That adds up to $609.55 in annual ingredient-cost savings compared with buying it ready-made.

Choose every ingredient. Start with tea you love, sugar for your culture and water. You know what goes into your brew because you put it there.

Make your favorite flavor, not just the one in stock. Bright ginger, juicy berries or fresh citrus—explore delicious combinations and find your own signature blend.

Bring living fermentation into your kitchen. Watch sweet tea transform into a tangy, refreshing drink, then enjoy the satisfaction of pouring a batch you made yourself.

Estimates from the FermentPro Recipe Book, based on the portions and frequency above. Actual prices and yields vary. Homemade costs cover ingredients; equipment, electricity, supplies and time are excluded.

A fridge stocked with your own creations. Plan your batches around your week and look forward to a refreshing homemade pour.

A flavor worth sharing. Make a classic tea-forward brew or try a new fruit-and-spice combination. Serve something that feels distinctly yours.

A small routine with lasting value. Reuse your vessels, keep your culture going and spend on simple brewing ingredients instead of another finished bottle.

Ready to start? Bring together your tea, a living starter and the right brewing setup. FermentPro helps take changing kitchen temperatures out of the equation with controlled heating and cooling.

A warm afternoon, a cool night, a different season. The same spot in your kitchen may not stay at the same temperature.

Temperature is one factor that affects how fermentation progresses. A calendar alone cannot tell you when every batch will taste the way you like it.

FermentPro gives your kombucha a dedicated, controlled environment, so there is less need to guess which cupboard or warm corner to use.

Heating and cooling in one countertop machine. Set the environment for your recipe within the 50–115°F (10–45°C) operating range.

Use a preset or adjust temperature and time manually. Viewing windows let you check progress without constantly opening the chamber.

When the cycle ends, post-ferment cooling helps slow continued fermentation. It does not replace refrigerator storage or checking your brew.

Start any time. Set your fermentation time. When the cycle ends, FermentPro automatically switches to cooling, helping slow continued fermentation without a manual temperature change.

Less clock-watching. More freedom. Plan your batch around your day, with an automatic cooling step already built into the routine.

Set the fermentation time for your kombucha recipe. Automatic cooling helps slow continued fermentation when the cycle ends, making your brewing routine easier to fit around the rest of your day.

Post-ferment cooling helps slow fermentation; follow your recipe for completion checks and timely refrigerator storage.

1. Prepare your tea. Follow the starter’s recipe using tea, sugar and water. Allow it to cool to the temperature specified before adding the culture.

2. Add the culture. Use the required amount of starter liquid and SCOBY in a clean vessel, with a suitable breathable cover for primary fermentation.

3. Set the environment. Place your prepared vessel inside FermentPro and choose the settings in your recipe. Check progress and taste when the recipe directs.

4. Finish and refrigerate. Follow your recipe’s bottling and storage instructions. For optional carbonation, use pressure-rated bottles and a tested second-fermentation method.

Enjoy a classic, lightly tart brew—or explore ginger, berries or citrus using a suitable flavoring recipe.

Make a note of your ingredients, settings and tasting observations. Each batch helps you learn what you enjoy.

Your next favorite flavor could come from your own kitchen. Keep the combinations you love, experiment with a new recipe and make every batch part of your own brewing story.

I’m Dr. Wanping Hu, a medical oncologist of more than 20 years, a PhD-trained microbiologist and immunologist, and a mother of three.

For much of my career, my world was medicine. But my journey into fermentation became deeply personal at home, while exploring food and fermentation for my family.

As I began making yogurt, kombucha, natto, tempeh and fermented vegetables, I kept encountering one practical problem: different ferments needed different environments.

I couldn’t find one appliance designed to create the different controlled environments these foods needed. So I created FermentPro®.

My hope is bigger than creating another kitchen appliance. I want to help bring fermentation back to the home kitchen—so making fresh, fermented foods can once again become part of everyday family life.
