The Irish Times had an article on Saturday 12 January from their Wine Correspondant John Wilson breaking down the price of a (retail) bottle of wine. While we don't agree completely with his figures, he was pretty close!
John estimated that a bottle of wine selling at €10.00 is sold by the winemaker for €1.50, and the Government gets €4.68!!
All we have to add is that if you spend a couple of euro extra, you'll get a wine that cost twice as much (and should in theory be twice as good!)
If I may finish with the Sales pitch, here at McCabes we sell wine after tasting it, not after pricing it! We have loads of wines under €10.00 including Gold Star winners from the Irish Wine Show, but have all those wines in the €10 - €15 range that are really worth trying!
