Tequila maker Patrón is being bought out by liquor conglomerate Bacardi for $5.1 billion. Bacardi previously owned 25% of Patrón International, which makes about $1.6 billion in revenue from its namesake tequila as well as a handful of other hard spirits. Six months ago premium-tequila competitor Casamigos, which was cofounded by George Clooney, was sold for as much as $1 billion to Diageo.
