Homebrewers and fermenting fans, this one's for you! This 25W heating pad is designed to keep your kombucha, beer, wine, mead, or sourdough starter at the perfect warm temperature for happy fermentation. It comes with a handy temperature controller that automatically cycles on and off to maintain a surface temp between 45-65°C (113-149°F), and it even shuts off at 60°C for safety. The pad is round, about 6.69 inches (17 cm) in diameter, waterproof (PVC surface), and has double-layer insulated wiring for even heating. It also includes two temperature strips to monitor your brew. Just place your fermentation vessel directly on top – no straps needed. It's a simple, low-cost way to speed up fermentation and get more consistent results, especially in cooler rooms. A must-have for any home fermentation station!
