Love kombucha. Herbal teas. Fever tree tonic waters of all sorts - cucumber mint, aromatic, and their orange and smoky ginger ale. NA wines and beers (if beer is your thing). I’m in Canada, and find the St. Regis Cab the best red, but everyone’s palate is different.
Some of the pre made mock tails are pretty good. I like the Clever G&T. You can make a good virgin Moscow mule with good ginger beer and lime.
The podcast “This podcast will kill you” has some great virgin cocktails under their “placeboritas”.
