I’m sure many careful wine lovers will notice that many wine bottles have a deep or shallow groove at the bottom of the bottle, like a wine “dimple”. In fact, this groove has an official name – the swan bottom.
There are many different opinions on the meaning of the swan bottom of a wine bottle, especially the discussion of the bottom and the quality of the wine it holds, but it’s safe to say that there is no necessary connection between the two. If there is, it is that bottles with deeper bottoms cost more to make because they require more glass and are more difficult to make, and some wineries use these more expensive bottles for their high quality wines. In addition, there are some more widely circulated and accepted arguments, so let’s take a look. 1. Make the bottle easier to place and avoid damaging the tableIn the beginning, glass bottles were blown by hand, and the bottoms of the bottles could not be perfectly flat and smooth, so artisans made the bottoms of the bottles concave to avoid sharp bumps on the bottom from damaging the table and to improve the stability of the wine bottles when they were placed. Nowadays, with more and more advanced machine-made bottles, making the bottom of the bottle smooth and flat is not a problem, and the recess has lost its original functional meaning, but is still preserved as a tradition.
2. Improving the structural stability and pressure resistance of wine bottlesTo a certain extent, the swan bottom improves the structural stability of the wine bottle and strengthens the bottle. Especially for sparkling wines, which usually carry a certain amount of air pressure, the presence of a swan bottom helps to distribute the pressure of carbon dioxide more evenly across the bottle, enhancing the stability and pressure resistance of the bottle. At the same time, this feature of the swan bottom also helps to reduce the possibility of bottle breakage during long-distance transportation. Winery,
