Last night I managed to brew my first imperial stout (1.085) with Lutra Kveik. I used one packet of yeast, and all I did was hydrate it. I figured I should pamper the yeast as possible to see if it worked. If so, I would have a reliable method involving little work. If not, I could always repitch later and learn a lesson.
I started the beer out at 68, more or less. I pitched on my patio and left it outside all night, because the temperature seemed about right. I brought it in the house this morning, and the temperature in here is about 75.
I didn't see any action until this afternoon, which was fine, because I am used to beers going over a day without noticeable activity.
At maybe 2 p.m., I pumped the keg up to 4 psi to see if it held pressure. You never know with O-rings. It seemed to hold fine.
Between 4 and 5, it was blowing like crazy. It was up around 13 psi. I am adjusting it to keep it around 10. I want a little carbonation, and I don't want weird yeast flavors, so I figure this is a good way to go.
So, is this activity about normal for kveik?
Beersmith thinks I'll hit 1.020.
