Experimenting with dry January for the first time and have been ordering all kinds of random things to see what sticks. Red wine has definitely been the 2nd hardest thing to replace (outside spirits) with a reasonable facsimile. I think the typically higher ABV and dominance of the alcohol in the flavor profile (especially for the Cab) is really hard to replace.
The best alternative I’ve found, and it’s by no means something you’d think was wine, is Acid League. Complex flavour profiles, don’t taste like boiled grape juice, but you have to put the “this should taste like wine” out of your thoughts. The other “not bad” option was the Leitz Pinot Noir, but the whites/roses/sparkling are superior and closer to the real thing IMO.
