The version in the 18th edition of your guide says 80ml Strega to 20ml red bitter liqueur. That seems like too large a difference to be classed as a variation, but perhaps you can clarify either way? Thanks
A really nice and refreshing drink, lower abv and a unique flavor profile. Strega leads the flavor, with some bitterness from the Campari and chinotto in the background. The chinotto soda dilutes and extends the drink - a very nice drink.
