The Story
The 1-inch Magnetic Stir Bar is designed for homebrewers preparing yeast starters in 500 to 2000 mL flasks. It provides steady agitation that keeps yeast in suspension, improving oxygen exposure and supporting faster, healthier growth before fermentation. The PTFE coating ensures smooth, quiet rotation and makes the stir bar easy to clean after use.
This stir bar offers reliable mixing performance on standard stir plates by maintaining stable rotation at various speeds. Its compact size provides enough movement to support yeast propagation for ales, lagers, and other batch styles that require active, well-developed yeast cultures. The coating helps reduce friction during use while providing durability across repeated brewing sessions.
Constructed with a magnetic core and PTFE exterior, the stir bar is compatible with the Wort Whipper Stir Plate and most other homebrewing stir plates. Its 1-inch length is suitable for typical starter flask volumes and fits securely within smaller Erlenmeyer flasks used for routine yeast propagation.
To use the stir bar, sanitize it thoroughly, place it at the bottom of a clean flask containing starter wort, and position the flask on a stir plate. Adjust the speed until the bar spins freely and creates a controlled vortex. This continuous mixing introduces oxygen and keeps yeast evenly distributed, resulting in a stronger pitch for fermentation.
Durable and dependable, the 1-inch Magnetic Stir Bar supports consistent yeast development and provides a compact, easy-to-maintain solution for everyday yeast starter preparation. Keeping a spare ensures you are prepared for any starter needed on brew day.
