Not only is "spritz" really fun to say, it's also quick and easy to make with just three ingredients. Basically, the Aperol Spritz is a home run.
Aperol is a bitter, orange and herbal liqueur originally from Northern Italy. I think it's fair to say that Aperol is Campari's little brother (and given that Campari now owns Aperol, I don't think they'd be mad at me for saying that.) It's not as bitter as Campari, it has a more pronounced orange flavor, and is lower in ABV.
Choosing a good sparkling wine for this drink is important, but don't break the bank. I like to use something on the drier side (less sweet) so it doesn't cover up the flavor of the Aperol. Prosecco is the most traditional, but a lot of the ones sold on the market are slightly too sweet for my taste. I have had the best luck using Spanish Cava, but you're free to experiment with whatever you have on hand.
The Aperol Spritz is a drink that is refreshing enough to please the novice drinker and complex enough to appeal to the seasoned boozehound.
