Coors Brewing Co., Golden, Colo., has begun marketing beer in a bat-shaped bottle as a salute to the game of baseball. The 18-oz. bottles are used for Coors and Coors Light. The "limited edition" bottles, being distributed this week, will be available for one to three months, depending on demand, the company said. The amber bottles are 11.5-ins tall and nearly 3 inches wide, with a simulated wood-grain texture molded into the glass. The bottles are part of the company's spring promotion in conjunction with the USASoftball World Series.
