Had the first taste:

Surprisingly (only because we're novices) good. The coffee flavor was very forward, and we thought maybe because we were drinking it a little early, perhaps the beer flavors need to develop some to balance out the coffee flavors. Still, pleasing effervescence and a very fine sip to savor at the end of a long day before going out to have more fun.
We've got an ale going and, soon, a California steam.
Question: we're being very hygienic but were wondering what happens if you're less fastidious with your corboy, etc? Do evil things grow in the brew, rending it nasty tasting and, perhaps, a little toxic?
