From “Degrees From The Palace Five Laundrymen, Washington, D.C. Pro Basketball Team” on Truth About It:

The Brewers were named after, you guessed it, a brewery owned by a guy named Heurich. If you’re familiar with the D.C. area, the brewery was located near Dupont Circle at 1229 20th Street. And guess what, they had a gymnasium at that brewery where the basketball team practiced.
