I am going to be brewing my first Belgian Dubbel and will be using WLP530. Ive never used this yeast before. OG estimate is 1.062. Planning on overbuilding my starter to harvest prior to pitching. Will be doing standard pitch rate of 0.75 on 64degrees of wort and let it increase temp naturally to ~70ish. My question is how much headspace do I need with this yeast in the fermenter? I have read that these belgian yeasts can be very active on krausen and crawl out of the fermenter. I am using Fermonster FV (7.1gallon) with modified ball lock lid and do not want my poppets to get clogged. Planning on getting 5.5gallon into the fermenter which would leave about 1.6g of headspace. Will this be enough? Anyone with experiences on WLP530, I would appreciate their comments on this. Thanks.
