Sourdough Home

The Sourdough Home can both heat and cool. The foldable Proofer cannot cool, i.e. it cannot bring its contents below room temperature. Although the Proofer has a temperature range of 21 – 49 °C, it cannot cool its contents below 25 °C at a room temperature of 25 °C. The Proofer is larger than the Sourdough Home and can accommodate a large mixing bowl, bread tins or other containers used when proofing bread dough. The Sourdough Home is smaller and has been specially developed for sourdough starters and can hold up to a 1 litre jar.

The health and growth rate of a sourdough starter are heavily influenced by feeding schedule (frequency) and temperature. To maintain a healthy starter ready for baking, many bakers store their starter at room temperature and refresh on a daily basis. Room temperature can fluctuate throughout the year and fermentation activity can become unpredictable and difficult to manage. Bakers often need to adjust feeding ratios and frequency to accommodate for these temperature swings. With the Sourdough Home, you can keep your starter at a consistent temperature year-round. No need to adjust ratios or feeding schedule.

Weekend bakers may not want to feed their starter everyday- it is unnecessary and wastes a lot of flour. Often, bakers store their starter in the refrigerator as an alternative to feeding daily. However, refrigerator temperatures hover around 38°F (3°C) which is too cold for the yeast and bacteria in starter. When it is time to bake, one must give the refrigerated starter a few refreshments to get it up to full strength ready for baking. Using the Sourdough Home to store your starter is the perfect solution. By keeping your starter cool, but not cold you can slow down fermentation, while not bringing it to a complete halt. Your starter will be healthy and ready to use without additional feedings.

With the SD Home, you can create a starter feeding schedule that works for you. Feed your starter once a day, every three days, or even once a week. Precise control over a wide range of temperatures allows you to manage the fermentation rate of your starter like never before and provides the ability to control when your starter peaks. Time to peak at various temperatures will depend on seed ratio, hydration level, and type of flour used. Experiment with your own starter to get desired results.

The amount of time it will take depends on two factors- the amount of starter and the discrepancy in temperature between your starter and the set temperature of the Sourdough Home. To shorten the time it takes for your starter to reach the desired temperature, mix it with water close to the set temperature of the Sourdough Home. If set to a warm temperature, mix your starter with warm water, and if set to a cold temperature, mix your starter with cold water.

In order to test the temperature of the Sourdough Home, we recommend using a probe thermometer inserted directly into your starter after it has been in the unit for several hours. We do not recommend setting an indoor thermometer inside the Sourdough Home.

A kitchen counter works well. Just be sure to avoid locations with extreme temperature variations, such as directly next to an oven, and to store it out of direct sunlight. The rear air vents should also be given a few inches of clearance for adequate airflow.
