The Fermzilla’s been sitting at 5 PSI since primary started about 5 days ago, so I just teased off the top and chucked in 80g of Chinook, 50g Nelson Sauvin, and 40g Citra as per the recipe. No purging or faffing. There was a small island of foam at the centre of the brew, indicating that some slight fermentation was still going on despite the Tilt graph having been flat for 2 days now. That bodes well; I wanted a tiny bit of activity in order to dispel any introduced oxygen, so hopefully we’ll get minimal DO and still great hop utilisation.
