MQFORU Sourdough Warmer — Precise 1°F Thermostat, 70–100°F, 12-Hour Timer

Elevate your sourdough proofing with precision warmth

In home baking, a stable warmth is the quiet multiplier behind reliable dough fermentation. The MQFORU Sourdough Starter Warmer is designed to provide steady heat, a compact footprint, and simple controls that fit into everyday cooking routines without fuss.

Precise, repeatable warmth

The warmer offers 1°F increments across a broad range, helping accommodate small ambient changes. For many bakers, a window around 95–100°F supports steady activity in the fermentation mat. Dual blue and red indicators show when the heater is active, and a glass cover is recommended to help minimize heat loss and keep the setup efficient.

• 1°F steps for accurate temperature control across roughly 70–100°F.
• Blue/red indicators for quick status checks at a glance.
• Glass cover recommended to improve insulation during proofing.

Smart timing for hands-off proofing

The built-in timer supports 0–12 hours of programming with auto shut-off, enabling steady, unattended proofing for sourdough, pizza dough, or yogurt while you focus on other tasks.

Durable, compact design

Designed for reliable power from a standard US plug, the mat features a 4.53-inch heating zone to work with jars sized 24 oz–40 oz. The slim profile fits neatly on counters or in drawers to save space.

• US plug ensures stable power and durability.
• 4.53-inch heating zone fits standard jars.
• Slim, space-saving form factor for versatile placement.

Smart memory and convenience

A smart memory function stores temperature settings, operating duration, and scheduled starts when power remains connected, allowing a quick, consistent startup across sessions.

Versatile uses beyond sourdough

Beyond sourdough fermentation, it can support yogurt culturing, fermentation of cheese or wine starters, defrosting meat, or softening butter—offering a gentle warming solution for small kitchen tasks.

• Suitable for dough fermentation, yogurt, and dairy-related experiments.
• Can assist with gentle warming tasks like defrosting or softening butter.

Note: This warmer is sold as a standalone mat; a jar is not included. For best insulation, consider placing a glass cover over the setup during proofing.
