I saw a lot of articles about the quality of wines, and the ten arguments about the theory of grooves are reasonable. But can the wine bottle bottom groove really identify the quality of the wine?
In fact, we talked about the role of the groove, the friends can clearly understand whether the groove has anything to do with the quality of the wine.
What is the groove?
The groove under the bottle is called the "bottom", also known as "punt". It not only has four legends, but also three major functions.
Legend 1: Before the era of machine bottle making, making a wine bottle was handmade by the worker's uncle. For the sake of the tool, a small scar will be left under the blown wine bottle.
This small scar can affect the stability of the wine bottle and cannot be placed on the table smoothly. Therefore, the master who blows the wine bottle made this little scar into what we now call the wine trough.
Legend 2: Structure is a factor that architects must consider when designing a building. Our wine bottles are no exception, and the structure is also required to make the bottles stronger.
When our wines come from all over the world, we need to ensure that the resonance between the bottles during the transportation of the wine bottles is reduced and the loss is reduced.
The bottles are stacked, the groove of the previous bottle is connected to the mouth of the bottle, and the bottle will have a support point, which will not be displaced with the vibration and inertia that occur during transportation. So this is another way of saying the role of wine troughs.
Legend 3: Nature produces many wonderful phenomena, such as gravity, such as air pressure. A bottle of sparkling wine is more attractive because of the pressure, but there are disadvantages in all things. If the quality of the high-quality glass bottle is poor, it is easy to explode. The wine cellar staff will be very dangerous. The risk will also increase.
Later, it was found that if there is a groove under the bottle, it is more favorable than the plane to enhance the pressure resistance of the wine bottle. Especially for such sparkling wines containing carbon dioxide, it is effective to avoid the possibility of explosion of the bottle, so this practice has been passed down.
Legend 4: This legend is somewhat negative, but after reading it, it is not reliable. Some people say that this groove is because the wine merchants designed such a big "pit" in order to reduce the amount of wine bottled.
At first glance, it is quite "scientific reason", but I believe that you love wine, you know that both the new world and the old world, the wine producing countries have strict legal regulations, no matter what kind of wine bottle the winery uses. The liquor in the bottle must be filled with 750 ml. So this statement was overthrown.
After finishing the four legends, let's talk about three major functions!
The three major functions of the groove
Role 1: Accumulation of sediment in wine
The little friends must have met and let us drink the drink before “shake before drinking”. As a "beverage" made from fruit, wine can not only produce sediment under long-term storage.
Because the early brewing technology is relatively backward, there may be slag after clarification and filtration, and the groove can precipitate the sediment at the bottom of the bottle and reduce the impurities in the liquor. For example: tartaric acid, tannins, pigments, etc.
Of course, we must also emphasize that no matter which kind of sediment is used, it will not harm people's health and quality of wine, but it will have an effect on taste and visual effect. If you find a wine with sediment, remember not to take too much alcohol when you take the wine. Try to avoid shaking the sediment, especially the old vintage.
Role 2: easy to clean
The friends must have encountered that the edge of the inner wall of the cup is not easily cleaned when cleaning the glass or cup. The bottle of wine is small and the cleaning is more difficult. At this time, when the wine trough is recessed, when the water is injected, the water will be scattered by the groove, because the impinging water will be cleaned to the edge of the inner wall of the bottle.
Role three: for better serving
A small step in the groove is a big step in the wine etiquette. In a very professional restaurant, when the sommelier pours the wine for the guests, he usually uses the thumb to hold the groove on the bottom of the bottle, and the rest of the fingers hold the bottle. This posture is not only professional, but also more convenient and elegant when pouring wine.
However, it should be noted that such a posture requires long-term wine etiquette training. I heard that a sommelier from a good restaurant in foreign countries will even step on a skater to train the wine etiquette.
