My wife now knows not to insist on pure cranberry juice, but rather to request a 100% juice blend and not “cocktail” (the cocktail is what the juice blend goes in). I finished the battery acid myself over the course of a few weeks, out of pure Floridaman cussedness. It was not pleasant.
It’s drier than I enjoy my wine, but it’s not undrinkable or anything. I would dilute it, just because I would assume that it already has a lot of sugar.
Though my uncle worked auditing cranberry bogs for the MA government (I now realize this might have been kid logic- he did something with cranberries as a state employee, I don’t know exactly what), so I grew up eating cranberries in all their forms.
