Last year the O’Sullivan dairy farm in Goleen, Co. Cork took the title of the National Dairy Council and Kerrygold Milk Quality award winners.

This week the family, with the support of their co-op Drinagh and Teagasc, opened the gates of their farm to the public.

Located on the Mizen Peninsula, Kieran & Catherine O’Sullivan’s dairy farm is run with their son Cathal and Kieran’s parents Donal and Mary.

Kieran and Catherine are the fifth generation of their family to farm the land at Dunmanus and were nominated for the competition by their co-op Drinagh. Drinagh has over 600 suppliers, whose milk is processed by Carbery.
