I should have checked the substitutions more carefully. I'd ordered ready made mulled wine being lazy and knowing it wouldn't be great, but thinking it would do. Half thinking the outdoor event I plan to use it at won't happen anyway. My thinking on seeing the subs and not recognising the name was that either it was a different brand or a cheap red that I could use for mulled wine. Either would be fine.
It's an 8% red called only "red wine" and marked vegan (no idea if that's relevant)
I know no one I could serve that to. Certainly not give as a present. How bad will it be?
