This is the largest glass in the Zalto line, and can actually hold a full bottle of wine, though you would never guess that because despite its size, the glass itself still feels light and agile in your hand. The design was not based on being the largest just for the sake of it- as with the entire line, the angles follow that of the Earth tilt angles of 24, 48 and 72 degrees.The size here is to allow for your biggest, most powerful and expressive wines to fully breathe and develop.
