I had a question along these lines too. Next weekend, I'll be brewing an oatmeal stout with about a 1.062 OG. My plan, originally, was to use Wyeast 1098 British Ale, but I've since ordered another batch of ingredients with the Omega Voss Kveik. Most of the research I've done says that it would be fine across a lot of different styles including a stout, but I wanted to get some thoughts from the forum.
My main deal is that I'll brew on Saturday next week, then I leave the country for 10 days on Wednesday. I don't want to do any temp control if I can avoid it which led me to wanting to try the kveik. Anyone else have experience using a kveik in a stout at mostly room temperature? I expect it to be clean and not have as much of the British character, but I really don't care that much for it to be to any certain style.
