St Germain Liqueurs, France
Take two parts Prosecco, one part St Germain and one part sparkling water, add some lightly bruised mint leaves. This is the ‘Hugo’, possibly one of the most refreshing, herbal and summery cocktails ever invented. It’s also impossibly easy to make. One minor note, this was invented in the Tyrolean mountains in Italy, so it’s properly pronounced ‘Ugo’.
