There has been a rumor about the groove at the bottom of the red wine bottle. One way to say is that the deeper the groove, the better the quality of the wine. Another insight is that the groove is present to reduce the inherent space in the bottle, in order to pack less wine in a larger bottle. However, all kinds of rumors are more or less based, but they are not a positive solution to this small groove.
Practical value of the groove
The first thing that realizes the red wine bottle groove is its practical value. Its biggest role is to accumulate the sediment in the wine. This is crucial for wine growers who do not have low-temperature crystallization technology in early wine production. The early winemaking techniques are relatively backward. After the wine is brewed, the wooden mesh filter is used to filter the slag and the peel. Therefore, the sediment and the tannin crystals are precipitated in the bottom of the bottle to precipitate when the wine bottle is upright. The object falls in the groove at the bottom of the bottle to reduce impurities in the premium wine liquid. In general, the more wine that needs to be stored for a long time, the deeper the bump.
The presence of the grooves also makes the bottle easier to fix during the alcoholization process. Related to this, the presence of the groove also makes the bottle easier to rotate. Early wines need to be rolled regularly (usually by inserting a roller on the bottom of the bottle, two to three times a day, 20-30 degrees of circumferential rolling to touch the fermentation of the wine) (foreigners call it Awaken the soul of the wine to sleep. Therefore, the groove also has the purpose of inserting the roller.
In addition, the groove prevents the bottle from exploding. The structure of the grooved bottle is very solid, the curve of the pit makes the bottom of the bottle as strong as the wall of the bottle, and the cavity of the champagne bottle is the deepest.
The aesthetic value of the groove
In fact, the appearance of the groove has gradually become a red wine etiquette and aesthetic ring. In foreign countries, the formal method of pouring wine, for example, when the bartender in the general restaurant pours the wine for the guests, they use the thumb to fasten the groove of the bottle, and the rest of the fingers hold the bottle, so that the wine is more professional and Elegant, but the way to get the bottle requires a long period of red wine etiquette training, otherwise, the bottle will be accidentally broken. From the aesthetic point of view, the changing groove design is more suitable for lovers who have beautiful requirements for wine. In fact, most wine lovers have their own habit of feeling a bottle of red wine.
One rumor about the groove is that the deeper the groove, the better the bottle of wine. The basis is probably that the early habit of the age of the wine can be distinguished by the depth of the groove. For example, a flat bottle (commonly known as a short bottle) is suitable for wines below the non-AOC level and other private wines that are not certified by the French government. Medium-deep grooved wine bottles are usually stored at AOC or above for about 3-7 years. High-depth wine bottles (generally called high-bottles): used to store high-grade wines for 5-10 years or even longer. However, this basis is not completely applicable to the present. Because of the innovation of brewing technology, the role of grooves in the precipitation of crystals has gradually become less important. Under the premise of quality assurance, the quality of wine is still in the consumer's own experience. There is no necessary connection with the groove.
