I tested this on one of my favorite sangria wines. It made the wine taste fuller and lighter. It was amazingly easy to clean with a little warm water. My son saw this and asked if it was for his juice. I said no at first but “why not?” I thought. So I poured his grape juice in not expecting any different but I could taste the difference even with grape juice. It made the juice seem sweeter and lighter. The scent of both the wine and the juice were brought out and made more delicious.
