Sourhouse Goldie Sourdough Starter Warmer and Quart Jar Set / Black

The Sourhouse Goldie Sourdough Starter Warmer and Quart Jar Set is designed to promote a healthy sourdough starter by creating the ideal microclimate for wild yeast. By holding your culture at 24–28°C, the Sourhouse Goldie Sourdough Starter Warmer keeps your starter in the 'Goldilocks Zone'—not too hot, not too cold, and safely above typical room temperatures. Temperature is the single biggest variable in sourdough baking, and seasonal kitchen shifts often lead to sluggish starters and failed loaves. This system removes that ambiguity before you put in the effort to bake. An intuitive light indicator continuously monitors internal conditions (blue for cool, gold for optimal, red for warm), supported by an included Cooling Puck for warmer summer days. Powered via a low-energy USB cable, it sits conveniently anywhere on your kitchen worktop.

This set pairs the warming unit with the purpose-built Sourhouse Starter Quart Jar. Crafted from durable borosilicate glass, the jar features straight sides, a completely flat base, and a threadless rim to eliminate the tight crevices where dried starter typically gets trapped. Volume measurement dots on the glass and an included silicone band make tracking your starter's rise effortless, while a soft, vented silicone lid keeps contaminants out while releasing carbon dioxide. Together, they form a simple, reliable system that builds confidence for beginners and brings consistency to experienced bakers.
