The idea behind Grassl Glass is to “bring out the best” by providing the wine with a large surface area to breath and a small opening to capture its aroma. Industry experts noted the importance of a focused nose and our balanced stem design. In November 2018, the first prototypes were produced and marked the start of glass comparison testing. Tastings and critical meetings were conducted amongst Burgundy, Bordeaux, Tuscany, Poemont, Castella y Leon, Loire Valley, Alsace, and Champagne with industry experts.
