In addition to his job Drew, along with Oswald, Kate, and Lewis, had a small beer business that sprung from Drew's hobby as an amateur brewer. The beer they created was called Buzz Beer, a concoction of beer and coffee that became extremely popular throughout the area. The beer was brewed and packaged out of Drew's garage.
Drew's boss Mr. Soulard tried to buy Buzz Beer from the circle of friends but Drew eventually reneged on the sale after realizing that he was hurting Kate, Oswald, and Lewis with his actions. He ended up buying the beer back for much more than Mr. Soulard paid for it, however.
In a Poker game, Kate gambled off her share of the company to Mimi Bobeck in the episode Mimi's a Partner (episode).
Drew traded his shares to Oswald for his car in the episode At Your Cervix (episode). Drew then traded the car back to Oswald so they would help him turn the garage into a home for Kellie Newmark, the brewery equipment was moved to Lewis & Oswald’s home.
