Luz, I thought it was, "The blacker/darker the berry the sweeter the juice... The darker the chocolate, the richer the taste"
Could it be "The older the berry, the more wrinkly the raisin?" LOL
I've heard 'The older the violin the sweeter the music' but if it is a wine metaphor, then "the older the berry the more concentrated the juice" Just try some Amarone della Valpolicella to learn this. Maybe next time we hang out!
Sorry, I do tend to overthink just about everything LOL
