UV rays do nothing to wine - or do they?
The UVA component of sunlight easily penetrates uncoated window glass and ensures that plants can also grow indoors. Put simply, UVA does not make you brown, but it does cause your skin to age. We are in the same situation as wine: its aging is also accelerated unfavorably when UVA hits the wine.
It all depends on the right conditions
For a good aging of the wine, besides the quality, the storage conditions are crucial. An unsuitable wine does not become more storable through good storage. However, an excellent wine that is suitable for storage can lose everything that makes it special in a very short time due to the wrong storage.
