I used Voss a month or so ago. It wasn't too hot yet so I pitched at 90, put on the brew belt and a sweatshirt around the fermenter, and it maintained between 94-97. Pretty much finished fermentation in less than 48 hours from pitching. Iirc, OG was around 1.068 and finished around 1.007. From what I read, Kveiks seem to favor stronger worts.
I have read that too, they perform better in the iipa strength vs the apa.
