If you're into complex flavours incorporating plenty of both aromatic and bitter components, I'm SO digging these Casamara Club sodas. They should be a definite hit with fans of amaros everywhere from Campari to Fernets.
I love that they're not sweet, either. The 'Alta' is a fizzy take on a Negroni, composed of sparkling water, lemon juice, cane sugar, and extracts of Italian chinotto, juniper berry, orris Root, mandarin orange, allspice, clove, anise, and Mediterranean sea salt.
My other fave is the 'Capo' AKA 'Como' - more of an Aperol Spritz kinda thing. This one's a little juicier: sparkling water, lemon juice, orange blossom honey, plus extracts of Mandarin orange, chamomile, peppermint, licorice root, grapefruit, juniper berry, clove, cardamom, and Mediterranean sea salt.
Here in Vancouver you can nab 'em at Drive Canteen.
