I've been fermenting my Hefe for 2 weeks at 62F and I took a hydrometer reading just now. My OG was 1.051 and my reading tonight was 1.010. There was still a large bubbled, light froth/krausen on top. Will this dissipate? Should I take it out of the cooler and bring it up to room temp? Is two weeks generally enough time to ferment a Hefe? Also, when I tasted the hydrometer sample, it was good, but I seemed to get an initial very sweet kick which left as quick as it came. Is this something that will ease out as it mellows in bottles? It also seemed ever so slightly carbonated, which was weird.
