Magnetic Stir Plate - Adjustable Speed

Yeast is one of the most important, if not the most important part of creating great tasting beer. Most brewers don't realise that the number of viable yeast cells can have profound impacts on the quality of your beer. Too little cells will generally be more of an issue than too many cells. 

The magnetic stir plate is an easy way to ensure your yeast gets the best start possible, not only will the stirring action constantly keep your dissolved oxygen content high while you make your starter it will also keep yeast in suspension and moving, this allows yeast to uptake nutrients and sugars and propagate in a healthy manner. 

We also recommend creating your starters in a warmer room, the heat of yeast activity will warm up your culture slightly but warmer temperatures will increases the rate at which your yeast propagates. 

This magnetic stir plate also includes a small magnet; if you plan on making larger starters (3L +) we recommend buying a spare larger magnet.

Erlenmeyer flasks are a great vessel to create starters in as they allow oxygen in without risking contamination. Erlenmeyer flasks are also made from borosilicate so they can handle the warmth of a starter as well as thermal shock to a point. As an extra point of protection we recommend laying cheesecloth or loose tinfoil over the mouth of your flask to protect microorganisms from potentially competing with your yeast.

Flasks are available in 500 millilitre, 1 litre and 5 litre.
