The Krausen is rising. My stock is getting low...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...

Boil Time : 60 min
Brewhouse Efficiency: 64.2%
Mash Efficiency: 70.6%
IBU : 20 (Tinseth)
Color : 6 EBC
Carbonation : 2.4 CO2-vol
Pre-Boil Gravity: 1.040

Fermentables (5 kg)
2.5 kg - Lager Malt 3 EBC (50%)
2.5 kg - Pale Ale Low Colour Maris Otter 3 EBC (50%)
Hops (8.5 g)
First Wort - 8.5 g - Apollo - 18.7% (20 IBU)
10 min - Boil - 5 g - Irish Moss
0.5 pkg - Lallemand (LalBrew) Voss Kveik
67 °C - 60 min
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.
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pitch half a pack of the Lallemand Voss, sprinkled directly onto wort at 35°C. No nutrient, but I did find a 4 years out of date pack of Mauribrew yeast that I chucked in the boil for the last 10mins.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.⁉
