Have you ever noticed a dent at the bottom of wine bottles, jam jars and even your favourite Nutella jar? These days even normal mineral water bottles have it. This seemingly useless dent is not only a design feature, it has functional purposes as well. Remember that one time when you balanced a bottle on your fingers? Well, this small dent was working hard to make sure the bottle does not fall off. But, has it ever crossed your mind if there are more reasons why most bottles and jars have a dent at the bottom?

It helps the sediment deposit around the circumference of the dent in the bottle, thereby stopping the deposit from getting mixed with the content. This explains why expensive jam, Nutella and wine bottles have a deeper dent than their cheaper kinds.

It makes it effortless for you to clean the bottle because water can easily spread around the bottle in an even manner.
