I've finally finished making my kegerator system able to handle two (corny) kegs at once. The last bit of the job was drilling a hole in the back of the fridge to run the gas line, so that the CO2 tank can sit outside the fridge; it went quite well and with a couple of rubber grommets it almost looks like it's supposed to have a red rubber hose sticking out of it. The two-way gas valve was a little bit of a hack, but Home Depot and teflon tape served me well.

On the left is a robust porter; kind of like Anchor Porter but a bit sweeter.
On the right is an English bitter. It's nice, although it has a doughy aftertaste I'd rather not have. It's supposed to be a clone of Bluebird Bitter.
