Beer baron Peter Coors will appear in court this week on a drink-drive charge.
He was driving home from a wedding reception when he ran a stop sign, was pulled over and failed a sobriety test, police said.
Coors' driving licence has been suspended and he is expected in court on Thursday. He has 30 days to appeal against the suspension.
Coors, 59, said he had drunk a beer about 30 minutes before leaving the wedding, the Rocky Mountain News reported.
'I made a mistake. I should have planned ahead for a ride,' he said. 'For years, I've advocated the responsible use of our company's products.'
A spokeswoman for Coors said he was charged with driving while under the influence. She said he had rolled through a stop sign a block from his home in Golden, Colorado, on May 28 and an officer stopped him in his driveway.
