The Austrian brand Zalto delivers handcrafted glasses from their manufactory. The glassblowers keep the Earth's axis and the position of the stars firmly in mind when making the wine glasses. Zalto glasses, like the Denk'Art glass series, have achieved cult glass status in recent years and are highly sought after by wine connoisseurs. Among them are experts such as winemaker F. X. Pichler and Michelin-starred chef Juan Amador. The glasses are extremely thin-walled yet dishwasher safe; their invention goes back to the well-known "wine pastor" and TV personality Hans Denk. The production of Zalto glasses initially takes place without lead oxide, which allows the delicate glasses to be both strong and erosion-resistant. This has a significant effect on the taste of the wine.
