The color of the bottle is important for the storage of wine, as is its shape and size. Glass is a material that has a certain fragility, but also provides stability to the container. The color of the bottles changes depending on the producer's wishes and local traditions and serves mainly a preservative function: indeed, dark colors act as a barrier to sunlight.
However, it should be considered that in the past glass was not purposefully worked to have colors like green or brown, but took on such shades due to impurities present in the blown materials.
Wine Bottle: Size Variable
The size of the bottles is also influential in the storage and especially in the aging of wines. In a small container like the quartino, wine tends to mature more quickly because oxidation depends on the amount of oxygen present in the bottle. In a small bottle, there is a greater possibility of having a larger amount of oxygen compared to a larger one.
