We started today's lecture with a bit of talk on yeast in a bit more detail than I'd covered before during the brewing process.
Our scheduled guest speaker to was Linda Chicka from ARIN IU-28 to talk about alcoholism - including the signs of alcohol addiction, how it affects work/productivity, and what to do about employees under your supervision who may be alcoholics. The facts and figures on the cost of alcoholism to taxpayers and businesses is, if you'll forgive the pun, sobering. It's a hard problem.
Finally, students handed in their brew tour journals from last week's trips. I spent the afternoon reading over those and editing the final exam. Tomorrow, we'll have a member of the state police talk to us for a while, then get in depth with more beer styles.
