I made a really nice tasting coconut milkshake IPA that I kegged a few weeks ago. The problem I am having with it relates to the dispensing of it and having a lot of foam. I get about 1-1.5" of beer which seems to equate to only what was settled and sitting in the beer line. Then when the tap actually starts drawing from the keg, all I seem too get is foam. If I let the beer sit for 5 minutes it does settle out and look pretty nice, but I don't know if this is typical for this style of beer or whether something is wrong. The beer is NOT over carbonated, and the recipe was 9.5 lbs Pilsen Malt, 1 lb flaked oats, 1 lb torrified wheat. Some late boil hops and 1lb of lactose with 10 minutes left in the boil. There were also hop stand additions and dry hopping along with 1 lb of shredded coconut and some vanilla beans in the fermenter. Being my first Milkshake IPA, I am wondering if this foaming issue is typical for this style and at all related to either the lactose or coconut additions? I just can't quite figure it out!
