Yep 23 lt. I pour the slurry onto a santised tea towel and just let it dry out, then break the bits up and keep it in clip lock bags at fridge temp's.
I've tried Kveik King, Loki, and Voss, I found not too much to choose between them, but Kveik King is probably my favourite. Be aware with ales (haven't done any lagers) that there's a similarity in taste almost independent of style, it's sort of a mandarin tone and can also have a faint hint of bitterness, best way I can describe it is the white pith you get under the skin/zest of citrus. I really like it in Belgians, and vintage style ales, but hate it in English bitters. Really should try it in an IPA but my next Kveik brew will be an export stout, so maybe after that. I did get a bit "Kveiked out" due to different brews all coming out with a "sameness" but it's remarkable stuff.
