Wort Whipper Magnetic Stir Plate - Compact

The Wort Whipper Magnetic Stir Plate - Compact is a space-saving magnetic stir plate designed to help homebrewers build healthier and more active yeast starters before fermentation. Compatible with flasks up to 5000 mL and optimized for starters under 2000 mL, this compact stir plate keeps yeast in constant suspension to support oxygen exposure, yeast growth, and higher cell counts. The adjustable speed dial allows brewers to fine-tune stirring intensity for different starter sizes and yeast strains.

Designed for yeast propagation and starter preparation, the Wort Whipper helps maintain continuous yeast movement during starter fermentation. Constant agitation helps improve yeast access to oxygen and nutrients, supporting healthier fermentation performance and reducing lag time when pitching into full beer batches. Its compact footprint also makes it suitable for smaller brewing spaces and homebrew workstations.

The stir plate includes one magnetic stir bar and features an adjustable speed control knob for precision operation. It is compatible with Erlenmeyer flasks and other flat-bottom starter vessels up to 5000 mL in size, though performance is best with starter volumes under 2000 mL. The compact housing is designed to save counter space while supporting routine yeast starter workflows for homebrewers.

To use, place the magnetic stir bar into a yeast starter flask, position the flask on the stir plate, and gradually increase speed until a stable vortex forms. Monitor starter activity according to your fermentation schedule before pitching into your beer batch. Clean the stir plate surface and stir bar after use.

Widely used in homebrewing yeast propagation setups, the Wort Whipper Magnetic Stir Plate - Compact provides a reusable and controlled solution for preparing healthier yeast starters and supporting stronger fermentations.
