Temperature sticker

Take control of your starter with our easy to read temperature sticker, designed to help you dial in the conditions for consistent, reliable sourdough. Simply apply the sticker to your jar and you’ll get a live read on your starter’s temperature at a glance. No guesswork, no second guessing why it isn’t rising. Sourdough thrives in a warm, stable environment. The sweet spot sits around 26–27°C, where your starter is active, healthy, and rising predictably. If you’re sitting below 24°C, fermentation slows right down and you’ll likely see little to no rise. Dishwasher safe for easy cleaning, just make sure you apply it to a clean glass jar surface so it adheres properly. This small addition makes a big difference. You’ll know when to move your starter somewhere warmer, when it’s ready to bake with, and how to repeat great results every time. Simple, practical, and built for everyday use, it’s one of the easiest ways to level up your sourdough game.
