Currently, wine products on supermarket shelves tend to be sold in generic small, medium and large sizes to convey the capacity. However, it is difficult for buyers to figure out the exact capacity just by looking at the bottles. This design rethinks wine bottles by dividing the body of a standard wine bottle (750ml) into three equal portions that can determine three different bottle heights. In this way, consumers can judge the exact capacity of wine merely by comparing the heights of the bottle. This idea can also be applied to all kinds of beverage bottles or scent bottles.
