This sounds delightful. Bought the Adriatico to make an almond margarita and it was delicious. May need to add raspberry eau de vie to my shopping list to try this one.
I use Freixenet cava, it comes in 200ml bottles. I always have those in the fridge for making single serve cocktails at home. If I am making more cocktails then I use a half bottle of Waitrose blanc de blanc champagne. I have found both of those to make delicious cocktails.
