Misa glass brings everyone to understand the secret of concave bottle bottom:

1.Due to physical and chemical changes within the wine during storage in a bottle, tartar and pigmentation will form. When standing upright, these deposits will settle at the bottom. If the bottle bottom is flat enough, these sediments can easily be poured into cups with wine; otherwise they might settle at mountain-shaped bottles where sediment collects in depressions in their sides instead of easily flowing out onto cups; creating problems when pouring it.

2.The concave curved surface is stronger, and the concave hole makes the bottom of the bottle as strong as the bottle wall, and is also designed to prevent the explosion of the wine bottle.

3. In the wine etiquette, the pits also provide convenience and balance for the sommelier during the serving process.
