You don't have to use it hot, but then it loses it's advantages, speed, and citrus flavours. The really good thing about it is after fermentation just scoop it out and dry it, I may never buy yeast again.Why did farmers in coastal Norway, where mean summer temps are below 20, develop yeasts that ferment at 30-40? Any thoughts?
Because of the temps, I won't try it soon, but kveik news is of interest.
I spoke to Derek from Bluestone about drying yeast, waste of effort because of the threat of contamination and dry yeast being so cheap. Though he did say Kviek you could probably get away with, as it is such a strong dominating yeast, and I think David Heath did something on drying Kviek yeast though I have never watched it.Good point Mark, and I agree in principal but what explains the historical usage of Kveik? How come the Norwegian farmers have been repitching for decades, I was thinking it may have something to do with the drying, where the yeast survive the process but the spoilage organisms don't, or at least are reduced to an insignificant number, and also the alcoholic strength where a hot fast ferment resulting in 8 - 10% abv doesn't give things a chance to thrive. Dunno, I think we need a bug guy/gal to chime in???

If you read a bit of brewing history you will find all beers were infected. Infected is a concept that came out of the work done on yeast by Pasture, Hansen and a bunch of others, anything other than the intended yeast strain is considered wild or an infection.
If you want a good quick overview of the history of yeast try
ONE HUNDRED YEARS OF YEAST RESEARCH AND DEVELOPMENT IN THE BREWING INDUSTRY
Yeasts were always sequentially cropped and the beer was always infected, they didn't have antibiotics, anesthetic or effective pain killers, these days we have pure strains of yeast and better beer, so no they weren't the good old days.

interesting. I bottled my first Kviek yesterday using yeast bay sigmond voss . 1052 to 1006 in 3 days at 34 degrees. finished lower than I expected but I did mash low .was going to be a saison but the hops I bought were mislabeled AA% so didn't trust them . changed to a APA as I had some mosaic on hand
floc'd like a beast . didn't bother cold crashing and yeast was a compact layer on bottom of fermenter like I have never seen before
hard to say how it tastes as all the samples I tried were 34 degrees . not optimal beer temp for detecting flavors. figure it will be carbed after 2 days in the bottle to try
kept a couple yeast samples to mess around with . thinking of trying it in a american brown next and then getting back to the saison
How was the 2nd day test, carb'd enough or needed longer ?
Temp? You fermented at 35 did you condition at that as well?needed longer. In fact i did 3 beers with it and all 3 took a while to carb for some reason.weord for a yeast that does a quick primary ferment
Nah. Don’t have any way to carbonate at that temp. They just sit in crates in my garage. Sure that’s a factor.Temp? You fermented at 35 did you condition at that as well?
Summer or winter we piching at 40-42 with local multistring Kveik. Clear and redy after 3 dayes.Why did farmers in coastal Norway, where mean summer temps are below 20, develop yeasts that ferment at 30-40? Any thoughts?
