@Paradox had a look into it, the '100% juice' kind that i like for straight cranberry is a juice concentrate blend of cranberry, apple and grape.. no sugar or artificial sweeteners
and it looks like the other varieties i like have sugar (quite a lot it seems), but it doesn't drive up the calorie count very much from the un-sugared kinds...
so, yeah, you're right about the sweet juice mixing there, fascinating stuff... i wonder what straight cranberry tastes like, i do enjoy dried cranberries :cirno_shrug:
