Crikey, there's a question! Could be red, white, pink or fizzy. Or all four. Depends too on your budget. But just as the Best Man's speech has to entertain the lads without upsetting Granny, so the wine has to appeal to all. My tip is go for a well-priced Sauvignon Blanc from New Zealand that will be light, crisp and aromatic, sort of dry and sort of medium. And for the red, a well-priced Chilean Cabernet Sauvignon; easy to drink with a touch of class. And as for the fizz with the wedding cake, don't go dry, go sweet. Sounds odd, sweet champagne, but believe me dry champagne and sweet wedding cake just don't work, whereas sweet (it'll say Demi-Sec or Riche on the label) works a treat. Best of all it doesn't seem sweet when you drink it alongside the cake, it just seems right. Pol Roger and Veuve Clicquot both do excellent ones, but then so does Tesco, suprisingly. I've been to so many weddings where guests either leave the fizz or leave the cake because they don't match. Bung some sweet champagne alongside the cake and everyone scoffs the lot.
