I've just read about the ideal wine for you Phil and it is from your neck of the woods too.
Adega Coop Borba Reserva (click on: 'Wines', then 'Reservas & Premiums' and then 'Borba Reserva') has a cork label, as well as a cork closure, to honour the fact that it comes from the important cork oak producing area - the Alentejo region.
It also seems that there is a stockist in Guia, which I believe is circa 30 miles from you. Cheers
