Although it is undoubtedly a play on the name Chateauneuf' (as in Chateauneuf du Pape) there is indeed a wine called Chat en Oeuf. As dave 123456 has correctly pointed out, it is stocked by Morrisons.
Apologies to proof for thread use.
Winebuyer no - but I did pick it up and give it the once over - as a couple of questions have been asked about it on here lately. Personally I am in training for my return to the Capewinelands in the Summer and so am working through a Pinotage phase at the moment. I met Paul Cluver ( jnr ) last week, a very nice man and tasted a range of his wines - mmmm, yummy.
This is a red wine - the name is a play on words for Chateau Neuf. They also do a "Goats do Roam" and a "Goats do Roam in Villages". The Chat en Oeuf is available from Waitrose and Booths by the bottle.
