Why does wine in larger bottles mature better?

In the 17th century, it was established that wine in a bottle with a cork stopper preserves its quality rather well and even improves if it is properly stored in wine cellars. In the course of development, in various wine-growing regions, characteristic shapes of bottles were designed, which are in their form and sometimes also in the colour of the glass typical of a vineyard region. Bottles are available in numerous sizes or volumes, e.g. 0.2 l, 0.375 l, 0.5 l and the most widely used 0.75 l, for which the name “buteljka” is used, but there are also larger bottles, the so-called magnum bottles, the volume of which can be 3 litres, 6 litres and even larger ones exist (9 litres, 12 litres), but they are rather rare! What is typical for magnum bottles is that the wine ages more slowly and in a better way and it keeps its freshness longer, while the flavour of the wine improves when it matures. The advantage is especially reducing the amount of wine exposed to various factors (e.g. oxidation) in comparison to the amount of wine that is not exposed to these conditions, so that the quality of the wine improves with the size of the bottle! The aging time of the wine, when we compare a regular bottle (0.75l) and a magnum bottle, is almost 1.5 times longer in the latter than with a regular one. As far as pouring is concerned, the magnum bottle itself is a little problematic, mainly due to its size and weight, so various pouring accessories are often used. One of such devices is also the WCanter device, on which you can insert a bottle of any size, from which you can then consistently and accurately pour wine with the help of a rotary wheel, which controls the inclination of the bottle itself and consequently the flow.
