Chef & Sommelier's series Open Up was first launched on the French market in 2006 after more than 2 years of trial and error to produce the most stylish design combined with the optimal cup. The glasses in the series are manufactured by Kwarx, a glass mass invented by Chef & Sommelier themselves. The glass mass gives the glass a nice luster, which emphasizes the wine's colors. Kwarx is also known for its incredible durability and is called the "unbreakable glass".

Open Up – wine glasses designed to unlock a wine’s full potential
The Open Up series from Chef & Sommelier is designed to maximize a wine’s aromas, flavors, and expression. Originally launched on the French market, the series is the result of years of dedicated development with a clear objective: to create wine glasses where form, function, and aesthetics work together to deliver an optimal wine experience – for both professionals and discerning home users.
Today, Open Up is one of Chef & Sommelier’s most popular collections, widely used in restaurants, bars, and wine tastings, while also being highly appreciated by wine lovers at home.
Optimized bowl for enhanced aroma and flavor
What defines the Open Up series is its gently angled, generously sized bowl, which allows the wine to aerate quickly. Increased contact with oxygen helps aromas open up more effectively, making the wine’s structure, scent, and flavor more expressive. The slightly tapered rim concentrates aromas toward the nose and guides the wine to the right areas of the palate, resulting in a more balanced and nuanced tasting experience.
These glasses are particularly well suited for wines that benefit from aeration, such as young red wines, fuller-bodied white wines, and complex blends.
Kwarx® crystal – durability and brilliance in perfect harmony
All Open Up glasses are made from Kwarx® crystal, an advanced glass material developed by Chef & Sommelier in collaboration with Arc International. Kwarx® combines exceptional clarity and brilliance with outstanding durability. The glasses are resistant to impact, scratches, and chipping, and are fully dishwasher safe, even with frequent use.
This makes Open Up an excellent choice for anyone seeking wine and champagne glasses suitable for everyday use without compromising on elegance or quality.
Precision in every detail
The rim of each glass is precision-finished to create a smooth and comfortable edge against the lips. This ensures a natural flow when drinking and enhances the overall experience without making the glass feel delicate. The balance of comfort, stability, and durability is one of the reasons Open Up is frequently recommended by sommeliers and wine professionals.
Wine glasses and champagne glasses for many occasions
The Open Up series includes a range of wine glasses and champagne glasses designed for different wine styles and serving occasions. The collection works equally well for wine tastings, dinners, and professional service, offering a timeless, modern aesthetic that suits most environments.
A natural choice for wine lovers
With Open Up, you get glassware designed to be used – often. The series combines wine-optimized shapes, durable materials, and elegant design, making it a reliable long-term choice for both beginners and experienced wine enthusiasts.
