Just a head’s up that I’ll be heading over to cover the Craft Beer Expo at St. Petersburg’s Mahaffey Theater today.

I’ll be posting updates here at the Stew and on my Twitter blog. Reporter Nick Bergus also will be there. He’ll be posting at Twitter after 3 p.m. at his blog.

What’s being offered?

Beer Tasting: More than 150 beers to sample

Beer Seminars : 6 free seminars, including Brewing Beer to Pairing Food

Beer & Cheese Garden: pairings of 10 beers and 20 cheeses

Samuel Adam’s Beer Dinner: Limited seating 6-course beer dinner

What qualifies as a “craft beer”? The Atlanta Journal-Constitution put it perfectly in this story about possible ramifications of the purchase of Anheuser-Busch by InBev:

Craft brewers — defined as producing less than 2 million barrels a year — have been riding high for the past few years. Volume of craft beer sold increased 12 percent in 2007, compared with 1.4 percent each for imports and noncraft domestics, according to the Brewers Association.
