I bottled it on friday. The beer has an intense Kveik twang and strong rye presence plus roast from the dark rye. It is interesting atm. I did not like it that much when bottling, but this is the type of beer that improves a lot with aging. FG is about 1.013, so I ended up with about 6.5% abv. This is lower than anticipated, but not so low that I would call it a failure. To the contrary, it is actually a big success because I want to do another stronger beer soon, which I now have to make a concept for, to increase my efficiency. I will do a batch sparge, first full volume sparge, then boiling down the liquid while doing a second "mash" with the grist. I will then extract the liquid a second time and add this to my first runnings. Plus I'll be doing biab, my new bag is in the mail. This should bump up the efficiency by 15 to 25%, which would leave me between 70 and 85% I guess.
I am looking forward to having the first one of this kveik brew in a few months!
