Goldie by Sourhouse + Cooling Puck

This warming device wraps your starter jar in gentle, auto-regulating heat beneath a clear borosilicate glass cloche. A three-zone light indicator keeps you informed about your starter’s temperature range at a glance. If your kitchen warms up during hot summer months, the included Sourhouse Cooling Puck can be placed inside the dome to safely cool down your starter before baking. Compact, energy-efficient, and easy to clean, it offers a controlled environment to ensure consistent, airy, and successful gluten free sourdough bakes year-round.

The Key to Consistent Gluten Free Sourdough Bakes

Baking exceptional artisan gluten free sourdough bread requires patience, technique, and proper temperature control. Unlike traditional wheat doughs that rely on strong gluten networks, gluten free starters depend entirely on starches, wild yeasts, and friendly bacteria to build rise and structure. When your kitchen drops below room temperature, your wild culture slows down, fermentation stalls, and rise times become unpredictable.

The Goldie by Sourhouse with Cooling Puck creates an ideal environment for your gluten free starter, helping you achieve consistent, airy loaves every season.

Why Temperature Control Matters for Gluten Free Starters

Gluten free grains such as brown rice, sorghum, teff, and millet ferment differently than gluten-containing grains. A cold kitchen causes fermentation to slow dramatically, leaving your starter sluggish and prone to over-sourness or poor expansion. Conversely, exposing your culture to high heat can kill beneficial wild yeast and lead to over-fermented, runny batter.

Maintaining a stable environment within the 24–28°C (75–82°F) range creates optimal conditions for lactic acid bacteria and yeast activity. This balance produces optimal flavour, excellent volume, and predictable peak timing so you know exactly when your starter is ready for mixing.

Thoughtful Design Meets Kitchen Convenience

Designed specifically for home bakers, this countertop companion offers functional features without cluttering your workspace:

By taking the variables out of starter maintenance, you can focus on perfecting your gluten free sourdough recipes with confidence and ease.

Frequently Asked Questions About This Product

Does a gluten free sourdough starter require a different temperature than a wheat starter?
Gluten free starters thrive in the same optimal temperature range of 24–28°C (75–82°F) as wheat starters. However, because gluten free flours lack elastic proteins, temperature fluctuations impact gluten free cultures more noticeably, making consistent warmth critical for a reliable rise.

How do the thermometer lights work?
The intuitive three-zone lighting system monitors ambient warmth inside the glass cloche:

• Blue Light: Indicates the temperature is below 24°C (75°F) and the starter needs gentle warming.
• Gold Light: Indicates your starter is in the ideal 24–28°C (75–82°F) zone.
• Red Light: Indicates the environment exceeds 28°C (82°F), signaling that you may want to introduce the Cooling Puck.

How do I use the Sourhouse Cooling Puck?
Keep the Cooling Puck in your freezer. If your kitchen warms up and the indicator lights show red, place the frozen puck inside the base of the unit under the glass cloche to gently lower the temperature surrounding your starter jar.

What size jars fit inside the unit?
The unit fits most standard sourdough jars up to a one-quart (approx. 1 litre) capacity.
