Repitching Calculator
Our harvest & repitching calculator is designed for brewers who want to save money, maintain a consistent brewing schedule and improve the final outcome of their beer.
Learn how to harvest and repitch yeast here.
Being able to calculate yeast cell viability is an important part of that process, which you can learn about here.

Dissolved Oxygen Calculator
Yeast cells need oxygen in the early stages of fermentation to produce sterols and unsaturated fatty acids for their membrane. Use this calculator to help determine the proper amount of O2 to give your yeast the boost it needs.
Assumptions:
- Oxygen supply is bottled pure oxygen, not compressed air.
- Delivery mechanism is a aeration/carb stone, not a venturi device or jet.
- Flow rate can be measured in liters per minute (LPM), delivered at 30psig or greater.
