One of the great things about the homebrewing community is the contribution of individual brewers to the group as a whole. I've learned a ton from the successes and failures of other brewers, and hopefully the Academy bloggers have helped you in the same way.
A while back I made a video on BillyBrew on how to step up a yeast starter. Using the instructions in the book Yeast, I showed how to grow a small starter into a larger one. But it was a manual process – until now.
Recently, a fellow HomebrewTalk member named Arthur (ajfranke) messaged me and said that he had taken my manual process and automated it in an Excel calculator. Sweet!
I want to share it with you all, so here's the link to the HomebrewTalk thread where you can download the calculator:
Big thanks to Arthur for creating this and giving back to the homebrew community.
