I do use the final volume of beer and correct for temp. I probably should be weighing my priming sugar but I have not as of yet. I haven't had off carbonation in the past (about 15 batches now) so I wouldn't think I screwed it up now.
I just poured one and it poured with 2/3 head. The head stayed for 5 min without diminishing. The beer does not seem overly bubbly but may be higher than normal carbonation. Those who are pointing to head retention may be onto something as I don't think I have seen any of the bubbles at the top of the head really break down. Is it possible that I am just noticing this because the head is really not dissipating at all and I am seeing just the accumulation of the whole thing. I know that wits may have more head retention grains but I also hop bursted the hell out of this one, don't the hop oils play into head retention.
In any case I will be watching my carbonation adds a lot closer from now on. But the fact still remains that I would like to keep this recipe close to what it is, as I really think its good, while reducing some of this retention. The base malts were interpreted from the HBT discussion on Lagunitas Sucks, and the hop schedule was my first burst/stand hopping (I wanted to see what I got).
Also, can hop flavor, oil or bitterness cover up over carbonation. I am finding that if I now concentrate on it it seems extra bubbly.
