Sourdough Home: A Starter Proofer & Cooler

The Home Your Starter Deserves

Precise Temperature Control

Great bread begins with a great starter and when it comes to sourdough starter, temperature is everything! The complex mix of microbes that cause bread to rise (and give your bread a distinctive flavor and aroma) are extremely sensitive to their environment. The Sourdough Home provides an easy way to precisely control the behavior of your starter. With degree-by-degree control from 41-122°F (5-50°C) you can maintain a consistent temperature or vary it to control the growth rate, aroma, and flavor of your bread. You can switch the temperature display from Fahrenheit to Celsius.

The inside of the proofer measures 5-1/8" x 5.5" x 7.5" which allows a 1 quart jar or two smaller jars to fit inside. Two shelves are included for flexible storage of small items.

As acclaimed sourdough baker Maurizio Leo from the Perfect Loaf blog explains in the video above "It's important that a sourdough starter is maintained in a consistent way, but the challenge there is that the temperature in your kitchen, even from one side of the kitchen to the other, can vary quite drastically... one of the great things about the Sourdough Home is that it allows you to effortlessly dial in the temperature that you want to keep your sourdough starter at."

Offers Flexibility

The Sourdough Home by Brod & Taylor offers a convenient, quiet, and compact way to maintain the temperature of your sourdough starter at the exact temperature you want to keep it at, whether that's a warm environment as you're preparing to bake with it, or a cool environment if you want to store it between bakes. The Sourdough Home both cools and heats, so you have total flexibility with how often you want to feed your starter, whether that's twice a day or once a week, or anywhere in between. 

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.

Seed Ratio: This is the ratio of active culture to AP flour to 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.

10°C / 50°F	3 days / 72 hours	1:4:4
12°C / 54°F	2 days / 48 hours	1:4:4
20°C / 68°F	1 days / 24 hours	1:4:4
