Generally, when we buy wine, we will find that the bottom of the glass bottle containing the wine has a deep or shallow groove. What do these grooves do?
Can make the bottle stand upright. In the original production of glass wine bottles, they were manually blown by mouth, and the bottom of the bottle was recessed into the bottle body to make the bottle body stand stably. The groove at the bottom of the glass wine bottle mainly plays a certain role in stabilizing the bottle body, and the size of the groove is related to the capacity of the wine bottle itself. Generally, in order to ensure the stability of the wine bottle, the larger the bottle body is, the more concave the bottom is the deeper the groove.
play a transitional role. Generally speaking, the older the wine, the better its quality, and some precipitation and lees will appear after long-term storage. The groove at the bottom of the wine bottle has a certain function of collecting wine residue, so that when pouring wine, there will be no wine residue in the whole bottle of wine due to the impact of the bottom wine.
