Mulled wine in an instant pot. Recipe calls to pressure cook apple juice with the spices then add wine at the end. Can we just pressure cook wine?

Sorry to disagree with Eric! Although wine has a lower alcohol level than other sorts of liquor, so is possibly safer, for safety it's best not to pressure cook alcohol. The manufacturer warns against it (it is flammable and the electronics are not adequately sealed; here's an explanation https://www.hippressurecooking.com/?s=alcohol+in+instant+pot.

What Eric said. You'll probably have to add something to sweeten it, and you may have to add water if it tastes too strong. I usually opt for honey, goes nicely with mulling spices.
