Take the guesswork out of maintaining a healthy sourdough starter with the NutriMill Sourdough Warmer. Designed to provide gentle, consistent heat between 90°F and 100°F, it creates an ideal environment for reliable fermentation – even in cool or drafty kitchens. Use it beneath your starter jar for gentle bottom heat or wrap it around the sides with the included Velcro straps to encourage faster activity.
