Thanks for the feedback, John. The previous method worked ok if you only ever used exactly two vessels, but if you wanted to use more than two (or even in some situations when only using one), it had problems.
You’re right that Breww no longer knows when a batch transitions from fermenting to conditioning. We’re planning on resolving this with Additional stages in brew schedule (batch schedule events) (and to some extent Increasing the number of the tank status icons (Chilling and Carbonated)) which should allow this to be far superior to just the two previous stages of fermenting and conditioning, as you’ll be able to add anything extra that you’d like, such as dry hopping. If you’d like to see this, could you give those a vote?
We’ve been planning internally to create the ability to customise the vessel groups, which would allow you to add Tertiary vessels. I’ve just added this here on the community, so if you’d like to see this, please give it a vote too Custom vessel groupings
Thanks again for the feedback
