UK - South Africa is for the first time the largest selling wine country in the UK. But does that mean it's any good?No one minced words last time I was in South Africa. One wine critic was, "still a couple of hamburgers short of a heart attack", according to the delicate phrasing of one winemaker. Another referred to the ubiquitous – and controversial – flying winemaker Michel Rolland as, "You know, that French idiot who flies around the world." We all knew who he meant. I wish I could have been over there to see what they said about the news that the British now drink more South African wine than French.
