Yeast Starter Stir Plate

Whether you are a master or a beginner, you will have to come face to face with yeast on your journey to brew the perfect beer.

Although, you can easily go to the store and buy a pack of yeast, the real flavor of homebrewing comes out when you are brave enough to make your very own yeast starter. 

Sounds too intimidating? We’ll make it easy by covering some of the best yeast starter kit plates.

Why a Stir Plate is Necessary For Yeast Starter

Decided to be traditional and grow yeast at home? Good choice! 

This endeavor will require a stir plate. Why? Because it is the most efficient and recommended method of growing yeast for homebrewing.

A stir plate works on the principles of magnetic force. They help in stirring liquids and are quite efficient at the job. 

To grow yeast at home, you need to constantly shake and stir your liquid because it requires a certain level of oxygen.

Since humans are incapable of stirring 24/7, you will need a stir plate to do the work for you. A stir plate ensures that you get the best yeast for homebrewing.

Now that we have established the importance of a stir plate, let’s take a look at some of the best stir plates for yeast starter.
