Sourhouse Goldie Sourdough Starter Warmer

The Sourhouse Goldie creates the ideal micro-climate for wild yeast by holding your starter in its 24–28°C 'Goldilocks Zone' – not too hot, not too cold, and safely above typical room temperatures. This removes any ambiguity or guesswork before you put in the effort to make a loaf, as an imperfect starter is the main cause of sourdough fails. 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 and adapter, its minimal footprint plugs conveniently anywhere on your kitchen worktop. Whether waking a culture from the fridge or establishing a new starter, it works the same way: Simply place the jar (like the Sourhouse Starter Jar) on the warming base, cover with the glass cloche, and wait for the starter to reach the optimal 'gold' temperature. The accompanying borosilicate glass jar features straight sides, a threadless rim to prevent trapped starter, and a vented silicone lid for effortless cleaning and carbon dioxide release. Designed to live on the countertop, it's also small enough to store when not in use. The starter jar is not included and can be purchased separately here.
