Elderflower liqueurs are delicately flavoured, aromatic and floral; they mix brilliantly with pretty much every spirit, both white and brown, even combining...
Fantastic aperitif version of the Hugo is 50 ml bianco vermouth, 10 ml St Germain or elderflower syrup. Muddle mint and elderflower lightly in gin balloon. Add ice, vermouth, lime wedge (squeeze and drop in), top with soda. Refreshing, low ABV.
I just call it a Hugo Light 🤷🏼♀️
