Apparently that 200 tokens I spent on the Brew of the Month club was well spent -- I got my second Brew in the mail this week, and it's a good one. Autumnal Acorn Ale is not only tasty, but it'll make you smell like Autumn Acorns, too. Drinking it will get you drunk and call Woodland Squirrels up to show you a little critter love (or hate). I sipped it for the first time last night during a Slave Pens run, and at one point I had three cute little squirrels showing their affection. Apparently they'll also throw acorns at you, though I missed that in the chaos of the instance last night.
Plus, it's an unlimited use item after 3.0.2 (14 day duration, though BotM members can buy more in Ironforge), which means you get as much alcohol as you want, and every time you drink one, you get an "empty brew bottle" to throw with a glassbreak bang. Very fun.
If you didn't round up enough tokens to become a BotM member, you're unfortunately out of luck -- I originally thought you could buy the brews in Ironforge even if you weren't subscribed, but no dice, and the brews you get sent are soulbound. You'll have to wait until next Brewfest to sign up for your monthly beer. Can't wait to see what shows up next month!
