I brewed a stout on Friday, August 6th. The recipe was:
1 lb Crystal 60L
8 oz Chocolate Malt (UK)
8 oz Roasted Barley - 550L
6 lb Dark Malt Extract Syrup
8 oz turbinado sugar
1 oz Nugget hops
1 oz Fuggles hops
Wyeast 1084 Irish Ale yeast
I steeped the crystal, choco malt and barley for 30 minutes at 155-160 degrees. I boiled 3 lbs of the extract syrup for 30 minutes w/ the nugget hops before adding the final 3 lbs of the extract, boiled another 30 minutes. I added the turbinado sugar with 10 mintues left (I wanted to up the alcohol content a bit) along with the fuggles. OG ended up a little light than what Hopville was calculating: 1.052.
I didn't make a starter, but did smack the yeast package the night before. Pitched at just under 71 degrees. Moved the carboy into a cooler filled with 66 degree water and left in the cooler for 2 weeks. Moved out of the cooler onto the concrete floor in my basement for another 10 days.
My mistake was not taking a gravity reading before I transferred it to my bottling bucket. When I went to bottle it last night, the reading was at 1.028! I'm just stunned because it really should be around 1.015 or lower. Outside of not making a starter, what could I have possibly done wrong? I've had a couple of extract beers do this now, but this is the most eggregious example of missed FG I've seen yet.
