MQUPIN Sourdough Starter Warmer — Precise 1°F Control, 0–24H Timer, Memory Function, 70–120°F

Warmth that supports your sourdough routine

In cooler kitchens, a stable fermentation environment can influence how your starter develops aroma, texture, and activity. The MQUPIN Sourdough Starter Warmer provides a dedicated warm surface that helps maintain a reliable, inviting space for your jar to rise. It’s designed to be a practical companion for home bakers who value consistent results without guessing.

Precise temperature control with simple ergonomics

Dial in a precise range from 70 to 120 degrees Fahrenheit (21 to 49 degrees Celsius) in one-degree steps. This level of fine tuning supports your starter’s rhythm while you focus on feeding schedules and flour choices. A practical tip in chilly conditions is to cover the jar to create a warmer microclimate and keep fermentation moving smoothly.

• One-degree increments for fine tuning
• Fahrenheit and Celsius options for clarity
• Intelligent heating supports steady activity

Automated rhythm and memory for hands-free baking

The built-in 0–24 hour timer lets you set a fermentation window and forget the counting. When the timer ends, a brief buzzer sounds for one minute (mute via a button) and the unit shuts off automatically. The memory function recalls your last temperature setting for convenience.

• Timer with a gentle one-minute buzzer
• Auto shut-off for tidy sessions
• Memory keeps your preferred temperature ready

Smart safety, practical design

Two color indicators provide immediate feedback on heating progress: red while warming and blue once the target is reached. With a modest 12W power draw and a long 50-inch cord, placement is flexible while keeping energy use sensible.

• Red and blue indicators for clear feedback
• Low power draw for efficiency
• Long cord for flexible placement
