Ahh...that smell

There is just nothing like the smell of fermenting grapes.  It's got that awesome yeasty scent, almost like fresh bread, combined with the aroma of the grapes themselves.  I go out to do a punch down (push the mass of grape skins and seeds back down into the must -- juice + stuff -- so the skins stay in contact with the juice) just so I can get a whiff of the smells coming my fermenter (which is a 20 gallon white food grade plastic garbage can).  I've come to associate the smell of yeasty fermenting grapes as a sign of fall, which has always been my favorite season.
