Yes, I’ve opened it a number of times now and absolutely no foam… Did one last pitch with a starter that I kept an eye on for five hours and it was very much going strong by that point. Yet that too succumbed to the void :[

The thing I like most about this kind of setup is how after the yeast is pitched and the pressure lid is closed, you don’t open it again until all the beer is gone… the peace of mind that the beer is kept hermetically in a steel vessel in a protective CO2 atmosphere. There have been a couple of second pitches in the past, and I’ve kind of branded those batches as second grade simply because I had to open the holy seal and re-pitch :D
