Keep your sourdough culture thriving with the NutriMill Sourdough Warmer, built for bakers who want consistent, reliable fermentation every time. This warmer delivers steady, even heat from either the bottom or the sides, giving your starter a stable environment no matter how drafty or cold your kitchen gets. Made from durable food-safe silicone, the flexible design fits most jars and containers. Adjustable Velcro bands make side-warming secure and simple, and the compact footprint (5 7/8 inches wide by 6 inches high) sits neatly on your counter without getting in the way. Whether you're nurturing your very first starter or maintaining a long-loved culture, you’ll have the confidence of knowing it’s always in its ideal fermentation zone. The charging cord and block are included so you can plug in and start using it right away with no extra accessories needed. Note: The warmer is designed to hold a gentle temperature between 90 and 100°F, which is close to normal body temperature. Because of that, it may not feel hot to the touch. This is intentional; higher heat can damage or kill your starter. That mild warmth is exactly what keeps wild yeast active and thriving. Crafted from durable food-safe silicone, the warmer flexes to fit most jars and containers. Velcro bands make side heating simple and secure, while its compact size (5 7/8" wide x 6" high) tucks neatly onto your countertop without hogging space. Whether you’re a beginner nurturing your very first culture or a seasoned sourdough pro, you’ll appreciate the confidence of knowing your starter is always in the sweet spot for fermentation. The charging cord and block are included, so you can plug in, set up, and start feeding your starter right away, no extra gadgets needed.
