I recently brewed a batch of pale ale using Kveik yeast (Omega Voss OYL-061). I fermented in primary at 29 degrees for about 14 days before kegging - it was oxygenated well and went absolutely wild in the first 3 days. It turn out at 5.6% ABV. The beer tastes good - I'm not getting any acetaldehyde flavor - but I only drank just under a liter and woke up with a terrible headache. Does Kveik still produce a lot of fusels under certain conditions?
