Regular.
After actually looking at the weather forecast earlier this week, decided to take my first steps with Kveik today to brew a (hopefully!) inoffensive summer golden ale. I need to dial in my boil losses, as I overshot my preboil gravity by 6 points (1.046) but only overshot my OG by 1 point (1.050) and ended up with 2 or so more litres in the FV (which is, of course, no bad thing).
Wanted to keep this simple with just a FWH charge to 20 IBU so as to explore what the yeast has to offer with no temperature control over the hot weekend ahead...

35 °C - however many days - Primary
Planning on splitting this after primary has completed, keeping one half as is and dry hopping The other half with 20g of Ekuanot.
The Krausen is rising. My stock is getting low...
I decided to just pitch half a pack of the Lallemand Voss, sprinkled directly onto wort at 35°C. No nutrient, but I did find a 4 years out of date pack of Mauribrew yeast that I chucked in the boil for the last 10mins.
A few hours later and there’s already plenty of activity with a nice white creamy Krausen forming. Looks like a bubble bath (and is probably about the right temperature!). Ambient temperature in the brew garage is currently 29° and the fermenter feels warmer than that, so - it’s a brave new world.
One thing I did notice with this brew was the amount of hot break during the boil. Honestly, it was like boiling 20 odd litres of split milk! Don’t know if this was a function of the grain bill, the low hopping rate or just that it was more visible in the light wort.⁉
