At the end of the 17th century, glass became the main material for wine glass selection. At this point, people gradually got rid of the monotony of drinking only by taste, and began to pay attention to tasting wine from the level of visual appreciation. Subsequently, the emergence of crystal glass made people's appreciation of wine move towards a more precise and elegant dimension.

At present, the materials of wine glasses are mainly glass and crystal. Although very similar in appearance, there are subtle differences in the aroma and taste brought by crystal wine glasses and glass wine glasses, which are caused by the different roughness of the two surfaces. It can be observed through the microscope that compared with the smooth surface of the glass, the crystal surface has more concave and convex surfaces. During the shaking of the wine glass, it is conducive to breaking the wine molecules to release the aroma; using it to hold the champagne, the performance of the bubbles will be better. , At the same time, the concave and convex surface on the glass wall can retain the foam of the wine body for a long time, and this is the soul of champagne. In addition, the crystal material has strong toughness and high wear resistance; the refraction point of light is also very rich, so that the wine glass looks particularly beautiful under the illumination of natural light; and its completely transparent characteristics without any color can be better It enhances the beauty of the wine and restores the original appearance of the wine body (the glass usually has a gray-green color). Based on the above factors, crystal cups will become the first choice for wine lovers.

According to the international standard, the content of lead oxide in the crystal glass must reach 24%, so the crystal glass produced in this way can be regarded as the best quality. In maintenance, the crystal cup can be washed with water. What needs special attention is that when cleaning the wine glass, be sure to hold the body of the glass to avoid pinching the stem of the glass, otherwise, the expensive crystal glass will only end up broken if you turn it gently. When necessary, detergent can be added. Here, wine professionals remind everyone to ensure that they are rinsed clean, because the residual detergent is also easy to form the phenomenon of "hanging the cup". Finally, after wiping the cup, it is best not to put it back in the box, otherwise the cup will absorb the taste, which will affect the drinking of the wine.

In addition, in the process of clinking glasses with crystal cups, the belly of the cup should be used to touch, not the mouth of the cup, because the mouth of the cup is the most fragile part of the crystal cup, and touching it can easily cause the glass to break. In response to the statement that the popular XX brand red wine glasses on the market have super performance and are not easy to break, wine professionals remind consumers that all glass or crystal products are fragile items. When purchasing wine glasses, you must look for them. Brand, to avoid unnecessary losses caused by blind purchase.
