Technically this post is about an Amaro Spritz from aCoupleofCooks.com but really any combination of sparkling wine, club soda / soda water (but not tonic water) and a bitter can make a spritz. So amaro, Aperol, Campari, Lillet…even St Germain is good.
The ratio mentioned in aCoupleofCooks is this: 3 parts sparkling wine, 2 parts liqueur, 1 part soda water. And that’s good. But if you want it lighter, just increase the amount of soda water. If you want it less bitter, you might even consider a 1:1:1 ratio vs 3:2:1. But try 3:2:1 first. Enjoy!
