Say Goodbye to Guesswork – Proof Like a Pro.Tired of wondering if your dough is warm enough to rise? Our revolutionary proofing base integrates a stainless-steel dough probe that monitors the core temperature inside the dough itself — not just the air around it. No more guesswork, just perfect fermentation every single time.

Precision is key! Our device offers degree-by-degree temperature settings from 70-110°F, with a built-in sensor for real-time monitoring. The auto-warming on/off switch and 24-hour timer function allow you to easily adapt to changes in ambient temperature and jar thickness, ensuring optimal results every time.

Designed for Every Baker, Every Vessel.Whether you prefer a classic starter jar, a glass mixing bowl, a stainless-steel bowl,our wide 6.5-inch base handles them all. Flexible proofing means you bake your way, without changing your tools.

Inspired by Bread, Built for Kitchens.Our rounded wood-grain design was inspired by the shape of a rustic artisan loaf. It’s not just a machine — it’s a statement piece that looks as warm and inviting as the bread it helps you create. Bright, easy-to-read LED display keeps you in control at a glance.

Unlock Better Flavor, Texture & Rise.When yeast thrives, your bread does too. By holding your dough at the sweet spot of fermentation, our system helps you achieve stronger gluten, more open crumb, and richer flavor. From sourdough fanatics to everyday bread lovers, this is the tool that transforms your baking forever.

Enhance your sourdough game with our optional borosilicate glass dome! It allows for precise temperature control, keeping your starter in the perfect “Goldilocks Zone” of 75-82°F (24-28°C) — where it’s most active and healthy. No more heating up your whole house; just bake perfect bread all year round!
