Irish dairy farmers provide the high quality cream used to produce the whiskey liqueur Baileys.

Launched in late 1974, Baileys Irish Cream is a cream liqueur made by the global drinks giant Diageo. From the outset, Glanbia Ingredients Ireland Limited has been the sole dairy supplier for Baileys. The cream liqueur uses a quarter of a million litres of fresh milk annually, making it the biggest buyer of Irish dairy outside the co-ops.

Some 82 million bottles of Baileys are sold to 180 countries around the world every year making the brand,

The single most successful spirit introduced in the last 40 years.

Baileys global success would be impossible without the high-quality dairy production on Irish farms. The production involves 40,000 dairy cows. Dairy farmer Brochan Cocoman from Kill in County Kildare is one of 1,500 farmers who supply Baileys. Dairy farming is hard work, with unsociable hours.

You need to love it to do it.
