You're signed in, but you're not part of a brewery yet. Create one to get started. (To join an existing brewery instead, ask its admin to add you.)
Add your tanks one at a time with "+ Add tank", or start from:
A tank is flagged "Acid due" after a batch of any of these styles leaves it. Each tank can also be set to need acid every few turns, in its tank settings.
Only an admin can change this list.
Download everything in this brewery as one file. A backup can be loaded into an empty brewery.
