You don't sign a 9,000-year lease if you lack confidence. Arthur Guinness wasn't messing around when he did just that in 1759 and his brewery still isn't today. They've made their name on Guinness Draught ever since. The inky black beer is inescapable on St. Patrick's Day and in Irish bars, but is perfect anytime, anywhere thanks to its balance of bitter and sweet. That's not the only Guinness beer, though. They also brew a Nitro IPA, blonde lagers, golden ales and more.
