Sourhouse Goldie Starter Keeper

The Goldie is designed to maintain a consistent, warm fermentation environment between 75-82ºF. It does not heat the air in your kitchen, but rather gently warms the glass cloche to keep your starter active and healthy, even in cooler homes.

The Goldie is specifically designed to fit quart-sized jars. For the best performance and temperature regulation, you should use a standard straight-sided quart jar that fits comfortably under the glass cloche.

The cooling puck is designed for warmer environments. If your kitchen temperature exceeds the ideal fermentation range, you can chill the puck and place it in the unit to help regulate the temperature and prevent your starter from overheating.

The unit features a three-zone thermometer with light indicators. These lights provide a visual signal of your starter's activity level, taking the guesswork out of determining when it has reached peak fermentation.

Maintenance is straightforward. The glass cloche and the cooling puck are dishwasher safe, while the base unit can be easily wiped down with a damp cloth.

The Goldie operates via a USB connection. This makes it versatile for countertop placement, as you can power it using a standard USB wall adapter or even a portable power bank.
