The material of the wine glass
The main materials of red wine glasses are crystal and glass. The aroma and taste brought by the crystal glass and the glass will be slightly different. It can be observed through a microscope that the surface of the crystal has more bumps than glass, and it hangs more on the glass. When it is used to hold champagne, the performance of bubbles will be better, and the small bumps on the wall of the glass can retain these bubbles for a longer time. This is the soul of champagne.
