The Burgundy glasses are mechanically manufactured from lead-free crystal glass. During the manufacturing process, bowl and stem are merged in a way that leaves no seams to be seen, making the glass look like it's made from one piece. The slightly shortened stem makes the glasses stable and fracture resistant, despite its thin nature This makes the glass suitable for your daily wine enjoyment. The elegant glasses are also highly popular with restaurant owners. Each glass from the Revolution Series has been designed to reinforce the aromas of wine through the glass shape. Its designers have adjusted the bowl's shape of this glass to factors such as acidity, maturity, tannin, viscosity and bouquet.
