I have been extract brewing for about two years now but I have gotten very discouraged with overly carbonated bottles and I am about to give up on brewing and move on to another hobby.
The problem I am having is overly carbonated bottles. I don't men a little. It is really bad. Imagine pouring a bottle and it immediately fills to the top with bubbles. This happens at least 80% of the time.
I have done at least 15 to 20 extract kits from Northern Brewer. It happens with every kit. I have a Cream Ale and an American Wheat left to do by the end of the year. If I can't get them to work out I will quite.
I called Northern Brewer twice about this. I follow the instructions exactly. I was told both times I called to not follow the instructions. The instruction for the kits are wrong. I tried using calculators but they seem to want me to input "vols" of CO2 but since I don't know what a vol is, I don't know. I have decreased the amount of sugar I put in the bottling bucket, sometimes by as much as 25% and they still come out overly carbed.
None the kits are complicated. I have never used an adjunct. I have tried leaving them in the primary for a month. Primary fermentation should be complete after a month. Sometimes two weeks in the secondary.
I add the sugar to the bottling bucket when I transfer and always make sure the solution is mixed into the beer very well..
I understand proper sanitation. I don't get off flavors. Just a lot of carbonation.
It's embarrassing. I don't drink many beers per week. Most I just give away to friends but then they report gushers of bubbles 80 % of the time.
