Ordered these (red #3 and white #1 versions) because we were down to our last Zalto Burgundy glass, and were having trouble finding new ones. Lucky us. We taste tested the Josephinen red #3 vs. the Zalto, and gave the Josephenin an ever so slight nod over the Zalto, offering a better bouquet on the nose and more robust yet refined taste in the mouth. The shape of the glass, while different from the Zalto, grows on you, and most importantly, seems to give a slightly fuller expression to the wine. We had a similar experience with the white #1. Just more impressed with the #3 only because we drink reds far more frequently than whites, but they are both superior glasses. Highly recommend.
