Make L. reuteri yoghurt, probiotic yoghurt, natto, koji & tempeh at home with the Reuter-i Pro — a 5-in-1 precision fermenter with 2L borosilicate glass jar.
Please note: Fermentation the temperature range is preset per mode and cannot be adjusted. Fermentation time is fully customisable.
The Most Intelligent Home Fermenter for Serious Gut Health
Inspired by the research of Dr William Davis (Super Gut), the Reuter-i Pro is a purpose-built precision fermentation station designed for the next generation of probiotic yoghurts, functional ferments, and traditional cultured foods — all from one device.
Whether you're fermenting L. reuteri yoghurt, L. gasseri, B. subtilis, natto, tempeh, kefir, koji or fermented vegetables like sauerkraut and kimchi, the Reuter-i Pro delivers consistent, reliable results that conventional yoghurt makers simply cannot match.
A Nourishme Organics sub-brand, designed in Australia.
Why the Reuter-i Pro Outperforms Standard Yoghurt Makers
Standard yoghurt makers run at fixed temperature ranges optimised for conventional dairy yoghurt. That's not good enough for the most beneficial probiotic strains. L. reuteri require 36–38°C over 30–36 hours to achieve the super-concentrated bacterial counts described in the Super Gut protocol — conditions that most home appliances simply cannot maintain.
The Reuter-i Pro solves this with water bath technology: heat is distributed uniformly around the fermenting jar, maintaining stable temperature ranges that protect delicate probiotic cultures from the fluctuations that destroy viability. The result is thick, potent, consistently reproducible ferments — batch after batch.
5 Preset Fermentation Modes
| Mode | Preset Temperature Range | Ideal For |
|---|---|---|
| Reuteri | ~38°C | L. reuteri |
| Yoghurt | ~42°C | Dairy and dairy-free probiotic yoghurt, natto |
| Natto | ~42°C | Bacillus subtilis natto, nattokinase-rich foods |
| Ferment | ~38°C | L. gasseri, B. subtilis, B. coagulans, Coconut Yoghurt |
| Tempeh | ~30°C | Traditional Indonesian tempeh, Sauerkraut, kimchi, lacto-fermented vegetables, Kefir using a starter culture, Rice Koji |
All modes feature a programmable timer up to 99 hours, giving you complete control over fermentation duration.

Frequently Asked Questions
Can I adjust the temperature?
No — temperatures are preset per mode and optimised for each fermentation type. Fermentation time is fully adjustable up to 99 hours.
Can I use plant-based milks?
Yes. The Reuteri and Yoghurt modes work with coconut milk, oat milk, and other dairy-free bases, though results may vary. UHT full-fat dairy milk produces the most consistent set.
My first batch was runny — is that normal?
For L. reuteri yoghurt, a looser first batch is common. The second batch made using your first as a starter is typically thicker and creamier. UHT milk produces the most reliable set.
Do I need to press Start after selecting a mode?
No. After selecting your chosen function, fermentation begins automatically — no Start button required.
Is a second glass jar available?
Yes — additional glass containers are available separately on the Nourishme Organics website, ideal for continuous batch fermentation.
How to use the strainer?
A small whey strainer is included. This utensil is only suitable for straining off whey if the yoghurt completely separates into curds and whey. It is too small to strain curds. Place the strainer on top of the glass jar and pour off whey.
Does the Reuter-i Pro yoghurt maker instantly reach the set point temperature?
No — and the lag is actually central to why these devices work the way they do.
Why it's gradual, not instant
- Thermal mass of the water – The heater has to warm the entire volume of water surrounding the jar, not just a small element. Water has a high specific heat capacity, so raising its temperature takes time and continuous energy input, even with a decent heating element.
- Heat has to transfer through multiple layers – Heat moves from the heating element → into the water → through the outer jar wall → into the milk itself. Each of those transfers adds delay. Even once the water bath is at the set point, the milk inside the jar lags behind until it equilibrates with the surrounding water — this can take anywhere from 20 minutes to over an hour, depending on the volume of milk and the jar's thermal conductivity (glass is slower than thin plastic).
- Starting temperature matters a lot – If you start with cold milk straight from the fridge (around 4°C) and are aiming for a reuteri ferment at ~37°C, that's over 30°C of temperature rise to achieve before the clock on your "36-hour ferment" should really start counting. Some people pre-warm their milk slightly, or scald it first, precisely to shorten this ramp-up period and avoid it eating into the effective fermentation window. Using UHT milk also helps.
- Thermostat cycling, not one-shot heating – Once near the set point, most units don't hold a perfectly flat line — they cycle the heater on and off to maintain temperature within a narrow band. This produces small oscillations of maybe ±0.5–2°C rather than a razor-flat target, but avoids overshoot and overheating the culture.
Practical implication for reuteri-style ferments
Because the ramp-up can eat a meaningful chunk of time (sometimes 1–2 hours for a full container), and because reuteri strains are already slow-growing, we recommend using UHT room-temperature milk or lightly pre-warmed milk rather than fridge-cold.
