1. The concave design at the bottom of the glass wine bottles allows the waiters to pour the wine to longer distances than usual. In addition, this also helps them to observe their surroundings more easily, avoiding spilling alcohol on guests. The pourer will use 4 fingers to support the bottom of the bottle, the thumb is placed in the concave part of the bottom of the bottle.

2. The concave bottom also helps to settle the sediment of wine (especially aged wine).

3. The concave bottom design is also a 'trick' of the manufacturer to 'fool' the buyer, giving the feeling that the wine in the bottle seems more.

4. When it is necessary to cool the wine, the concave bottom will increase the contact area at the bottom of the bottle with the ice in the ice bucket, making the cooling process faster.

5. Helps the bottle stand more firmly, especially when placed on uneven surfaces.

6. Easy to overlap when stacking and helps the bottles above to fix better.

8. Curved surfaces bear the best load than flat ones, so concave will make glass bottles more impact resistant than flat bottomed bottles.
