There was some doubt at the back of my mind as to whether or not half an 18 month out-of-date sachet of Kveik would be viable, but this morning around 08:00 there was enough Krausen to cover almost 50% of the brew’s surface. An hour later the cover was complete, we’re up to 8 PSI on the spunding valve, and all vital signs are good. Go do your thing, you mad Norwegian bastard.
