The Glenlivet distillery is the oldest legal distillery in Speyside, and is known as "The single malt that started it all". It was founded in 1824 and it has operated almost continuously since. The distillery remained open throughout the Great Depression and its only closure came during World War II. The Glenlivet distillery has grown in the post-war period to become one of the biggest single malt distilleries in order to keep up with global demand; The Glenlivet brand is the biggest selling malt whisky in the United States and the second biggest selling single malt brand globally. Today, the distillery is owned by the French alcoholic beverages company Pernod Ricard and they oversee the distillery's production of 5,900,000 proof litres per annum. The majority of this – enough for 6 million bottles – is sold as The Glenlivet single malt, with the remainder being used in Pernod Ricard's blended whisky brands.
