Sorrento drinking glass 296 ml 2-pack without stem from Zwilling is a must-have when you serve white wine. The glasses are made from borosilicate and have double walls, which prevent the wine from heating up from your hand. The wine also appears to float due to the optical illusion, giving a luxurious and modern impression. Another advantage of these wine glasses is that they withstand temperature differences - you can both heat and chill them without them breaking.
