Guinness is brewed at the St. James's Gate brewery in Dublin. There is no brewery named the "Guinness Brewery."
On December 13, 1759, Arthur Guinness singed a 9,000 year lease for the St. James Gate property. He paid £100 for the lease (about $160.32 US), and the rent on the brewery is just £45 (about $72) per year.
3 million pints of Guinness are brewed every day at St. James's Gate (using 8 million liters of water), and an expansion is underway to increase that production by nearly double.
Guinness is brewed in 49 countries worldwide. Guinness owns 5 of the breweries in 5 countries: Ireland, Malaysia, and three in Africa: Nigeria, Ghana and Cameroon.
Guinness Storehouse, built in 1904 and once the largest working tun (large cask for holding liquids), for fermentation in the world standing 26 meters high (about 85 feet), it is now the largest tourist attraction in Ireland. Opened to the public in 2000, more than one million visitors pass through its doors annually.
The Gravity Bar at the top of the Storehouse is the highest bar in Dublin at 46 meters (151 feet) off the ground, offering a 360 degree panoramic view of the city and surrounding areas.
