Grassl Glassware
Every Grassl Glass is handmade by artisans with over 30 years of glass blowing experience. The result of their skill is a glass with remarkable precision, highest quality materials and unbelievable thinness that feels weightless in your hand. All shapes were developed with the feedback of world renowned winemakers to establish a clear benchmark for how their wines should unfold and be enjoyed by everyone.
Today, a number of very talented winemakers are already using Grassl glass to show the best side of their wines at the Domaine:
Burgundy: Domaine Roulot | (Domaine Rougeot | Henri Boillot | Domaine Confuron-Gindre | Domaine Yvon Clerget
Bordeaux: Ferdinand (Château Palmer)
Rhône Valley: Domaine Jean-Luc Jamet | Domaine Alain Graillot
Champagne: Domaine Jacques Selosse |Champagne Pierre Paillard

Swiss Design + Mouth Blown
Every Grassl Glass is handmade by a specifically trained artisan, carefully inflating molten glass encased in a carved wooden mould. This method is known as mould-blowing.
- Gathering molten glass
The artisan starts the process by gathering a piece of molten glass from the furnace with a blowpipe. Once the correct amount is withdrawn, the molten glass is then pre-shaped. - Blowing into the wooden mould
Next, the pre-shaped molten glass is encased in a handmade wooden mould and carefully inflated. The artisan has extensive experience to not only gather the correct amount of molten glass, but also to blow it beautifully and uniformly. - Pulling the stem
After the glass is fully inflated and removed from the mould, the stem is pulled to the exact specified length. Once the correct length is achieved, the stem is straightened through further rotting the glass. - Attaching & forming the base
To achieve our signature balance stem design, a ball of molten glass is attached to the end of the stem and flattened to a specified diameter and thickness. - Slow cooling down & cracking off
The glasses are gradually cooled from 500°C to room temperature, necessary for improving durability & hardness. A straight line is then etched along the rim and a burner is used to crack off the cap from the bowl. The final steps are the sanding of the rim and fire- polishing to smooth out any edges.
MATERIALS
An oxy-fuel fired furnace melts glassmaking sand, soda, dolomite, potassium, potassium oxide and recycled glass. The result is a 1700°C hot, lead-free molten mass resembling the composition of pure rock crystal.
CRAFTMANSHIP
Twenty years of glassmaking experience are required to consistently craft the Grassl Glass Collection. Five artisans are needed to produce a single stemmed glass during the hot-shaping phase. Followed by a slow-cooling process with an additional five steps for finalisation.
VALUES
All Grassl Glass designs are based on core principles of functionality and usability. Whilst the Vigneron Series is built on the feedback of the most renown winemakers today, the Elemental Series focuses on the absolute essentials of wine drinking.
