Just kegged an extract wheat beer and beer smith had it coming in at 1.049 and finishing a 1.013. My actual OG was1.046 so not far off but my FG was 1.020.
It was London 1968 yeast. I've used it before and always finished much lower than this. I made a 2L starter harvested 1L for later use and pitched 1L in this beer.
One concern I did have is I use a 19 gallon drum as a swamp cooler that I keep the fermenter in. I pitched at 65 degrees but than put the fermenter in the swamp cooler and the water was only like 48 degrees. Could this have shocked the yeast?
