Additional Notes:
Brewing went fairly smooth. Nothing to note. except an apparently stuck lauter that may have just been the bottom of the runnings after all.
After 9 days fermenting at 60F in the basement shower (in a water bath), gravity had dropped to 1.021 (originally thought it was 1.053, but forgot that refractometer readings needs adjusting when alcohol is present). I moved it up to a 69-70F closet to finish for another 7 days, where it dropped to 1.020. Unfortunately the taste may have changed on me; I kind of regret warming it up like that, because it was so clean-tasting before.
I added the dry hops on day 16 and moved it back to the 60F bathroom to clear up and dry hop. Once some good trub falls out, I'll keg it and age it cold.
