The confines of the Prince George's County Correctional Center shouldn't be confused with the California vineyards of Ernest and Julio Gallo, but don't tell that to inmate Joseph Patrick Walters.

When Walters, 31, arrived in Circuit Court for his attempted armed robbery trial yesterday morning from the jail, he was sweating, stumbling and mumbling, according to sheriff's deputies.

Indeed, Walters was under the influence of his own homemade wine, a libation he made from water, fruit and sandwich bread known among inmates as "jump steady."

Corrections officers noticed a smell of alcohol about Walters as they prepared to take inmates to the courthouse for trials and hearings, said jail spokeswoman Christy Merenda.

Officers administered a breath test, and Walters registered a blood-alcohol level of 0.17, she said. Under Maryland law, a reading of 0.13 can bring a charge of driving while intoxicated.

Assistant State's Attorney Joan Lieberman, who was prosecuting Walters, said she had not seen anything like the Walters' episode in her 10 years as a prosecutor. "Not {in Prince George's} where the guy was in jail," Lieberman said.

She asked Circuit Court Judge William H. McCullough to reschedule the trial.

Although Walters' attorney, Elvira White, objected, the judge granted the delay, saying Walters was drunk.

Walters, who has been incarcerated since December, told jail officials he had been making the wine while working in the jail's kitchen.

Merenda said corrections officers searched that area and found a pint bottle of Walters' wine hidden behind a ceiling panel. She said that Walters lost his inmate worker status and faces disciplinary action.

"I wouldn't advise anyone to try to make this," Merenda said. "Can you imagine all of the germs and bacteria in that jar?"
