I have an over carbonation issue with a recent batch and I can't figure out why. I open a bottle (12oz), wait a moment, then foam comes flowing out of the bottle. When foaming finally stops, I have about 1/3 of a beer left. FG was steady at 1.022 for over a week before racking to secondary, then spent over 3 weeks in the secondary before bottling (6 weeks total). Used 3oz of priming sugar for a 5gal batch.
Batch details:
PM with 9lbs grain + 4lbs DME
OG = 1.085
FG = 1.022
ABV = 8.4%
Bottled on 1/22
when in secondary, added cold pressed coffee and cocoa powder (100% cocoa, no sugar)
I've used (http://www.tastybrew.com/calculators/priming.html) to calculate proper amount (after the fact), and that results in 2.6oz. I can't believe 0.4oz too much is causing the amount of over carbonation we are seeing.
Any thoughts to what my issue is?
