Bottled a beer the other night, usual routine for a beer at 2.5ish volumes. I usually pull a half pint or so a day when I think its close, when it's right I'll bottle. Set up my gear and got to work with the beergun. bottled a case or so, poured one for myself while I was at it, and it was right where I wanted it. Got a 6 pack into the second case and I notice I'm getting less foam in the neck, didn't think too much of it at the time. Opened a bottle out of that case a cpl days later and it's maybe 1.5 vols. Tried another, same thing. Tried one from the first case and its 2.5. Very strange.
The only thing different on this batch from every other is I dry hopped in the keg. I did not remove them while I was bottling. Could that have anything to do with it? Ideas?
Thanks
