What a perfect little tool

Ditto all the positive reviews. Can't say enough about this little gadget. I ordered it as soon as it was available. Perfect size. Works great. I'm so glad I bought it.

Thought it was great, then.....

The first two days I had the SD home, I thought it was great. Then on the 3rd day, starter was flat. 12 hours later it was still flat and very cold to the touch. Temp set on78 F. but the starter certainly wasn't. I'm not sure what's going on.

Review and Question

I have been using the Sourdough home for 2 weeks. So far, the results are great.
My question, I maintain two starters. One with 100% hydration used for my modified version of the Country Sourdough The other is a 50% hydration used for my modified version of the More Sour bake Prior to baking the temp used for each starter is different. I can work past that using the Proofer. My question (finally) will the more sour ratio 50g (rye & AP flour), 25g water, 10g mature starter be about the same or much different to maintain as listed in the guideline grids above? I'd like to maintain both of them in the starter home rather than using the fridge for one or juggling them between the two.


My starter has been in the frig for months. I took it out, fed and put it in it’s new home. Fed every 12 hrs times 3, and it is bubbling away!!! Thrilled with this purchase.

The home your starter deserves.

Great bread begins with a great starter. When it comes to sourdough starter, temperature is everything. The complex mix of microbes that cause bread to rise - and give your bread that distinctive taste and aroma - are extremely sensitive to temperature.

Precise temperature control. The Sourdough Home provides an easy way to control the temperature of your starter. With degree-by-degree temperature control from 5 - 50°C (41 - 122°F) you can maintain a consistent temperature or vary the temperature to control the growth rate, aroma, and taste of your bread.

Your starter. Your schedule. Adjust your feeding schedule from hours to days, even once a week, and vary the temperature to control the aroma and flavor profile of your bread.

Sourdough starter maintenance. Sourdough starter is a living colony of yeast and good bacteria. Like any living thing it needs to eat - just flour and water. Feeding your starter the proper ingredients at the right time is the first step in creating great sourdough bread. Using the precise temperature control of the Sourdough Home, you can adjust starter feeding times to meet your schedule.

As starter ferments and grows, it creates CO2 bubbles that cause the mixture to rise in its container. The ideal time to feed starter is when the rise has peaked - all of its food has been consumed - and before it begins to fall again. By using a constant seed ratio (quantity of flour and water) and controlling the temperature, you can control the feeding schedule to hours, days or even a week. Use the guidelines below to get started.

TemperatureTime to FeedSeed ratio
7°C / 45°F5 Days / 120 Hours1:4:4
10°C / 50°F3 days / 72 hours1:4:4
12°C / 54°F2 days / 48 hours1:4:4
20°C / 68°F1 day / 24 hours1:4:4

Seed Ratio: This is the ratio of active culture to fresh flour and water. The more active culture used, the faster your starter will grow and peak. For daily maintenance a 1:4:4 ratio will keep your starter thriving without growing too fast.

Note: Your starter may vary slightly from these results depending on the flour used and the specifics of your culture.
