Fred and Percy Bulmer grew the apples at their family orchard at Credenhill in Herefordshire which would be later used to make the cider for which they became known. Production was initially at Ryelands Street in Hereford, the original buildings, including cider cellars survives today as the Cider Museum and King Offa Distillery. Production moved to the current Plough Lane site in the late 1970s. Today HP Bulmer makes 65% of the UK's five hundred million litres of cider sold annually, and the bulk of the UK's cider exports. From 1937 to 1949, Bulmers operated with Wm. Magners of Clonmel, expanding into Irish distribution markets. From 1949 Magners withdrew from this partnership but retained rights to trade under the name HP Bulmer Ltd in Ireland.
