Not while flying, eh?
But I've always been a big fan of dry cider (west-country schooling...) and recently, I've been drinking some lovely ciders thanks to Sainsburys...
I would heartily recommend Westons Vintage for getting whacked (8% ABV, and it doesn't taste it...)
If you like fruity, either Petronella's Blush (cider with a little black currant juice/liqueur in it) or St Helier Pear cider (which is what I'm on right now... very sweet though...)
