When I was getting my zymurgy degree at Davis, the instructor had us all take a couple agar plates home to swab anything that caught our eye. The idea was to impress on the youngsters in the class that cleanliness is vital when making drinkable fermentables, and that almost nothing that you deal with day-to-day is actually clean from a clinical point of view.
I won the sweepstakes with a kitchen sponge. I also took second ... with the tea towel. Makes sense, when you think about it. They stay nice and damp, in a nice warm place, with lots of goodies on them.
Beer, because thankfully brewing works in spite of us filthy humans.
