We now have two samples of Prosecco frizzante to try, from different ends of the swank spectrum - and different producers. Because they are not sealed with a mushroom cork in the way that champagne is, we pay only regular wine duty on them, not the double duty that the champagne cork attracts. Hooray! Cheaper fizz! Prosecco seems to have been flavour of the summer in Ireland this year. When I've shaken off this stinking cold and we have a few minutes to do the tasting, watch this space for developments.
