Move over, Green Line. Goose Island launched a new Blue Line beer last week, and it's only available on draft in Chicago and just for this summer. (Although their publicist said, "Then we'll see what happens!" So who knows—maybe if we drink a lot of it, they'll keep it around.)
Made at the Fulton St. brewery, Blue Line is a pilsner with three kinds of hops and clocks in at 4.8% ABV, which means it's light enough to drink a couple without feeling it too much. I ordered a pint at Primebar last night, and it was clean and crisp, with some floral notes. It's just a nice, easy-drinking summer beer.
The only catch so far is that it's kind of hard to find—the list of spots you can get it will grow, but right now, find it at Primebar, Beer Bistro and Lincoln Square Lanes.
