Cultivate Your Sourdough Starter with More Precise Temperature Control!

Great Bread Starts with a Great Starter

When it comes to sourdough starter, temperature is essential. The complex combination of yeast and microorganisms that helps bread rise — and gives your bread its unique flavour and aroma — is highly sensitive to temperature.

Precise Temperature Control

Sourdough Home provides an easy way to control the temperature of your sourdough starter. With degree-by-degree temperature control from 5°C to 50°C, you can maintain a consistent temperature or adjust it to control the growth rate, aroma, and flavour of your bread.

Your Starter, Your Schedule

From hourly to daily, or even once a week, you can adjust your feeding schedule and fine-tune the temperature to control the aroma and flavour of your bread.

How to Maintain Your Starter

A sourdough starter is a living culture of yeast and beneficial bacteria. Like any living organism, it needs to be fed — simply with flour and water. Feeding your starter the right ingredients at the right time is the first step to making excellent sourdough bread. With the precise temperature control of Sourdough Home, you can adjust your starter’s feeding schedule to fit your lifestyle.

As your starter ferments and grows, it produces carbon dioxide bubbles, causing the mixture to rise inside the container. The ideal time to feed your starter is when it reaches its peak — when all the food has been consumed — and before it begins to fall again. By using a consistent starter ratio, meaning the amount of starter, flour, and water, and by controlling the temperature, you can manage the feeding schedule over several hours, days, or even a week. Use the guide below to get started.

Starter ratio: This is the ratio of active starter to fresh flour and water. The more active starter you use, the faster your starter will grow and reach its peak. For daily maintenance, a 1:4:4 ratio will keep your starter healthy without growing too quickly.

Note: Your starter may vary slightly depending on the type of flour and the specific condition of your active starter.

Control Your Sourdough Starter Growth with Sourdough Home

With precise temperature control, managing your starter has never been easier. Sourdough Home is designed to heat or cool as needed, keeping your starter at the perfect temperature. Feed your sourdough starter according to your schedule — from twice a day to once a week. Adjust the temperature to fine-tune the flavour, aroma, and texture of your bread.

Q&A

Q: How is Sourdough Home different from the Folding Proofer?

A: Sourdough Home can both heat and cool. The Folding Proofer cannot cool — meaning it cannot lower its contents below room temperature. For example, even if the proofer has a temperature range of 21°C to 49°C, if the room temperature is 25°C, it cannot reduce the contents below 25°C. The Folding Proofer is larger and can fit large bowls, loaf pans, and other containers used for proofing dough. Sourdough Home is smaller and specifically designed for sourdough starter, fitting jars up to 1 litre.

Q: Why should I keep my sourdough starter in Sourdough Home?

A: The health and growth rate of a sourdough starter are greatly affected by feeding schedule and temperature. To keep a healthy starter ready for baking, many bakers keep their starter at room temperature and refresh it daily. However, room temperature can fluctuate throughout the year, making fermentation activity unpredictable and harder to manage. Bakers often need to adjust feeding ratios and feeding frequency in response to these changes. With Sourdough Home, you can maintain a consistent starter temperature all year round, without needing to adjust ratios or feeding schedules as often.

Q: What about simply storing my sourdough starter in the refrigerator?

A: Weekend bakers may not want to feed their starter every day — this is unnecessary and can waste a lot of flour. Many bakers store their starter in the refrigerator as an alternative to daily feeding. However, refrigerator temperature is usually around 3°C, which is too cold for the yeast and bacteria in sourdough starter. When the refrigerated starter is needed for baking, it must usually be refreshed several times to regain full strength. Sourdough Home provides the perfect solution. By keeping your starter cool, but not too cold, you can slow fermentation without stopping it completely. Your starter stays healthy and ready to use without extra feeding steps.

Q: I do not want to feed my sourdough starter every day. What feeding schedule do you recommend?

A: With Sourdough Home, you can create a feeding schedule that suits your starter and lifestyle. Feed your starter once a day, once every three days, or even once a week. Precise control across a wide temperature range allows you to manage your starter’s fermentation rate like never before, giving you more control over when your starter reaches its peak. The time it takes to peak at different temperatures will depend on the starter ratio, hydration level, and type of flour used. Try experimenting with your own starter to achieve the results you want.
