Why You Should Harvest & Repitch Your Yeast

Whether you started brewing large batches or began with a tiny operation in your home, you already know how quickly brewers can go through large quantities of yeast. When you’re experimenting and trying to improve your brews, you could end up going through massive amounts of yeast. This is especially true if you try to start fresh with every batch. Here, we’ll look deeper into why you should harvest and repitch your yeast, both for business reasons and ensuring the quality of your beer after brewing.

Reduces the Cost of Brewing

The larger your operation is, the more yeast you’ll have to go through. It doesn’t make fiscal sense to constantly buy new yeast to use for each batch when you can harvest the yeast you already have and repitch it. If you operate a large brewery, repitching yeast can save you a ton in operating costs by eliminating many unnecessary purchases of new yeast. If you’re just getting started, you already know how precious every penny that goes into your brewing is. You don’t need to waste it by buying yeast you don’t need when you have reusable yeast on hand.

Ensures Consistent Batches

One of the most important reasons why you should harvest and repitch your yeast is that it helps keep your batch brewing consistent. Every time you use a new batch of yeast for your beer, you run the risk of the yeast behaving in unexpected ways. Yeast is a living organism, after all. You can’t always know how it will react once you begin using it. Repitching yeast gives you a better starting point because you already have an example of what the final product will look like using that very same yeast. You can create more consistent batches of beer by reducing the number of variables you have to deal with, such as how your yeast will react.

Protects Beer From Spoilers

As long as you stick to the most sanitary practices when it comes to harvesting and storing your yeast, you can help protect your beer from spoilers in batches of new yeast. It’s important to remember that repitching your yeast correctly can help ensure that you use yeast that you’re familiar with and won’t react in a way you weren’t expecting. However, if you repitch your yeast without following proper sanitation practices, bacteria can start to multiply and ruin your final product by introducing flavors you don’t want.
