9. The Indentation In The Bottom Of Wine Bottles
Wine bottles come with an inward indentation right at the bottom, and while some would say that these are to indicate the quality of the wine, that’s not the real reason why. Some also say that the indentation serves to collect sediment in the liquid, and that the indentation also serves to prevent the sediment from flowing out when you pour the wine.
The real reason for the indentation is that wine bottles were originally handblown and that creating a seamless bottom isn’t doable if you want the bottle to stand in place. The handblown process creates a nub at the bottom, wherein it gets pushed, creating the indentation and having that seamless bottom.
