I have been brewing for around 15 years now and do mostly All Grain but this batch is a extract batch and I have never seen a beer do what this one is doing in it's fermentation. The bubbles in the airlock are bubbling about every 2-3 min but there is still alot of yeast on the top of the beer. Most of the time if it is bubbling this slow there is very little if any yeast still on the top. Is this a stuck fermentation or what. I have never had a beer ferment this slow before. If has been in there for 11 days at 68F. The beer was Pitched with wyeast and also I run pure O2 first. The OG was 1.047 and it is 1.018 now. I know it still have to come down some but this is very slow and I am not getting a good feeling about this one. Which is funny because I have had very few of the problems that alot of people have had in my 15 years of brewing.
