Taste is useful, but disruptive.
Opening the jar repeatedly can be messy, subjective, and easy to forget.
Introducing
Know when your kombucha is ready.
A modern readiness sensor for home brewers — built by McGill researchers, now in active home-brewer validation. Not for sale yet; help us test whether it solves a real problem.
Observe the batch Track changes without claiming the batch is ready.
- Home-brewer validation open
- Sensor and model performance are still being evaluated.
- BoochBot is not selling a product yet.
Let's be real
Home-brewing readiness is still a judgment call.
Regular brewers already know the ritual. The hard part is deciding when a batch has crossed from too sweet to ready without over-testing, disturbing the jar, or relying on calendar guesses.
Timelines drift.
Temperature, starter strength, tea, sugar, and room conditions change the finish.
The best signal is personal.
Some brewers want brighter acidity; others want a softer finish or more fizz.
Brewer guide
Trying to tell when kombucha is ready?
We wrote a readiness guide for home brewers covering taste, aroma, timing, pH limits, bottle pressure, alcohol risk, and batch notes. It also explains the problem BoochBot is trying to solve.

What is being tested
A smaller sensor path before the appliance.
The near-term hypothesis is a high-quality readiness sensor or kit: something a brewer can place near a jar, use with clear instructions, and optionally share batch observations from. The goal is to learn whether this solves a real readiness problem before major appliance spend.
Readiness guidance for active home brewers
A simple kit experience that respects the jar ritual
Optional batch notes, photos, and follow-up interviews
How validation moves forward
Evidence first, appliance later.
Survey and interview regular home brewers.
Validate the pain, current methods, interest, data comfort, and willingness to pay.
Use trials and small sensor arrays to collect real evidence.
Compare sensor signals against actual fermentation labels before claiming prediction quality.
Revisit the full BoochBot appliance with data behind it.
Keep the full appliance vision, but make it follow evidence rather than hype.
