I've been brewing in the basement all year long, since I started! it's perfect! dark to keep UV light away from the yeast, and a fairly constant 66-68 degrees, no matter if the AC is on or not!
but then again, my basement is a pretty nice "man-cave" fully finished/carpeted walk out, huge couch with huge screen TV, 7.1 surround system, a full bathroom with a shower/tub combo, and a separate workout/hobby room with the weight bench, hobby table, gun safe, etc.
I have 2 batches in fermenters aging right now, 2 batches aging in bottles, and one batch in "consumption" stage. ...although it's almost gone, so I might be cracking open a bottled batch a week early!
