Literally 'Summer red wine', it's an ultra-simple tasty drink for hot days. I've known bartenders to make it with a shot of brandy or rum. I go without but by all means try it!
Note: I make this by the cup so measurements are estimates.
It will probably need more sugar, but i like to add it slowly. I've found there's a fine line between bitter and overly sweet when it comes to this drink. Add bit by bit, mixing and tasting as you go, until you have a refreshing summer drink.
