A wine accessory is generally any equipment that may be used in the storing or serving of wine. Wine accessories include many items such as wine glasses, corkscrews, and wine racks.
Wine glasses are a type of glass stemware that are used to drink and taste wine from. Selection of a particular wine glass for a wine style is important, as the glass shape can influence its perception.
Wine bottle openers are required to open wine bottles that are stoppered with a cork. They are slowly being supplanted by the screwcap closure. There are many different inceptions of the wine bottle opener ranging from the simple corkscrew, the screwpull lever, to complicated carbon dioxide driven openers. The most popular is the wine key, sommelier knife or "waiter's friend" which resembles a pocket knife and has a small blade for cutting foil and a screw with a bottle brace.
Wine poppers are another means of opening wine. A hollow spike is driven through the cork of a bottle. A cartridge of carbon dioxide is then pressed to release a short burst of gas. The sudden increase of pressure dislodges the cork and the wine can then be served. Two problems can arise with this method: synthetic "corks" may be too dense to penetrate, and bottles not intended for pressure may break.
