Be warned, yeast harvesting can be risky ground. One of the few batches I’ve tipped out was thanks to harvesting mishap. Let’s cover some of the things to consider.
Before you add your dried homebrewing yeast to your wort, you need to rehydrate it with water that has been boiled and cooled.
This will test the yeast’s viability and increase its performance.
If you add dried yeast directly to your wort, up to half of viable cells can be destroyed.
As the sugary wort solution moves into the dry cell it damages the cell wall.
Managing homebrew yeast is one of the pillars of making great beer.
Whether you are mixing tinned concentrates or running full mash brew rigs, all homebrew needs healthy and active yeast.
I’ve had a handful of homebrew failures over nearly two decades I’ve been making my own beer. All can be traced back to poor yeast management.
