Coors, 59, was driving a 2004 Jaguar when he was pulled over in Golden by the Colorado State Patrol just before midnight on May 29, according to officials in the Jefferson County District Court clerk's office.
He was arrested for suspicion of driving under the influence after registering a blood-alcohol level above the legal limit of 0.08. He was also cited for failing to obey a traffic control device. The Denver Post reported that a state trooper spotted Coors running a stop sign.
The Post said Coors issued a written apology: "I should have planned ahead for a ride," he said. "For years, I've advocated the responsible use of our company's products. That's still my message, and our company's message. I am sorry that I didn't follow it myself."
Coors took over as president of the family company in 1987 and in 2000 was named chief executive of the brewer. The company has 8,500 employees and rang up $4 billion in sales in 2003. Adolph Coors merged with Molson to form the Molson Coors Brewing Co. in 2005.
Coors, a tall, silver-haired figure familiar to many as the face of the Coors television ads, was a political novice in 2004 when he decided to seek the Senate seat being given up by Republican Sen. Ben Nighthorse Campbell. He won the GOP primary, but was defeated in the 2004 general election by Democrat Ken Salazar.
Coors faces a July 20 court arraignment.
