John Hughes started flirting with ceramics and pottery as early as 1965 with a kiln in his garden shed in the family home on Llantwit Road, Treforest.
In 1971 the family purchased the derelict Dan-y-Graig pub in Treforest near Pontypridd and opened the Groggshop as it was then called.
In 2005, following Wales' rugby union victory in the six nations by winning the grand slam, a limited edition Grogg was produced to commemorate the event.
The production run was limited to 151 pieces, being the number of points Wales scored during the competition.
