I just poured another bottle of my amber ale, and couldn’t even get the bottle over my glass before there was a beer fountain. Over the past few weeks this has become an increasing issue with this particular batch. This beer was in primary for 26 days, after which the FG was 3 points higher than projected. This batch was bottled on February 20. In reviewing my brew log, it seems I might have over carbonated this beer. I projected 2.5 gallons to package at 2.5 volumes at 68*F, which indicated 2.2 ounces of table sugar. Well, I filled 24 12-ounce bottles (288 ounces/128 ounces/gallon) which is 2.25 gallons. According to the calculator, I would have added 2.0 ounces of table sugar to carbonate 2.25 gallons at 68*F. Does anyone agree or have some other explanation for my bottled beer fountains.
