They have a great Web site that lists all the events. You'll find a bunch of Howard County happenings -- including beer tastings at the Perfect Pour, Victoria Gastro Pub and Frisco Grille. Victoria in Columbia has tastings every day. I'm a fan of their tasting sampler. Judge's Bench in downtown Ellicott City has something called "Judge Your Elf Night."
You can check out my take on Beer in Howard County, which I need to update. But the real action over the next 10 days will be on the Baltimore Beer Guy, Beer in Baltimore and the other local suds blogs. For more about the beer week (and this history of beer in Baltimore), check out the Sun.
