Some commenters found this over-sweet. Meehan & Gall specify Aperol whereas, in your specs, you simply indicate the generic "bittersweet orange-red aperitivo". Because of the emphasis on cherry liqueur, we avoided the further sweetening Aperol would have offered and went, instead, with Campari. So when you indicate the generic aperitivo are you leaving it to the discerning drinker to decide according to their own preferences? After all, there is a world of difference between Aperol and Campari.
