First batch was an Amber (Fat tire clone) Extract kit. OG 1.05. FG 1.02. Used wyeast 1728. Was in primary for 3 weeks then bottled. It's been bottled almost 4 weeks now. First week was at 65 degrees and then I moved upstairs so it was around 70 the last three. When I open I get a slight pop and a little bit of foam on top when I pour but then it dissipates in a couple minutes and seems pretty flat overall. I've sampled each week since bottling, it has gotten much better tasting...but does not seemed to have carbed up any more in the last two weeks. I also do not detect any yeast in the beer I left in the fridge 24 -48 hours before sampling and no yeast at the end of the poor. It might still be in suspension but it seems fairly clear. I primed with corn sugar as follows using one of the online calculators 3.7 gallons of beer 2.6 volumes at 70 degrees and weighed out 3.5 oz of corn sugar. The first 1.3 gallons went in a mini keg and was primed at a lesser amount. Any thoughts appreciated. Thanks.
