Funny, I happen to like aronia - when they’re ripe. The 2nd berry is better than the first. LIke eating spicy food, once your mouth gets used to it, the experience is different.
But generally, I don’t make fuss about which cultivar has the most of a particular nutrient, or even which fruit.
I agree with whoever suggested the idea that the healthiest fruit is the one you eat. If a berry has 50% more of something, but doesn’t taste good, I’d rather just eat 50% more of the good tasting one.
