With the volume of Aperitivo here we didn't have high hopes, expecting excessive sweetness. But we were very pleasantly surprised. We found it restrained, elegant and yet delicious. We haven't had a bottle of Sambuca to hand since our late teens, when it was all the rage along with its cousin Ouzo. So, speculatively, we substituted Galliano L'Autentico and a dash of Absinthe.
