Tyrrells (crisps) Tyrrells (crisps) Tyrrells is a manufacturer of potato crisps owned by KP Snacks. Tyrrells was founded in Leominster, Herefordshire, in 2002 by farmer and entrepreneur William Chase. Within several years of its creation, Tyrrells expanded its market into Europe and later into the U.S. Tyrrells has received numerous awards for the taste and quality of its crisps, both in England, as well as internationally. In April 2008, Chase sold a majority stake for £40 million to Langholm Capital. Chase had a long running dispute with Tesco over stocking his potatoes, and so refused to sell them any supplies of Tyrrells.
