CONCORD (KTVU) - A Concord man is behind bars after agents found a massive stash of guns and booze.
53 year-old Sterling Albert is facing felony charges after the ATF says it found unregistered guns and two illegal stills at his Concord winery and home.
They say he was making wine, rum, and whiskey, all illegally.
Agents then found more than 40 weapons at his home, including guns and grenade launchers.
Albert's bond stands at $2 million.
Authorities say those stills weren't only illegal, but could have exploded.
