I bottled up my Russian Imperial Stout about a week ago keeping it in my basement at 64.4 ambient temp thought I would try a bottle of it today to see how it is going. Alas foam foam foam sigh...I am hoping I did not overprime my beer I put 4.1 oz of dextrose in at bottling. Not sure if I overprimed or if it just needs more time to settle. Any ideas?
