The global trend of wine buyers needing to see the colour of their wine in a clear bottle (especially for Rose) has led to many buying preferences for these clear bottles as well as a penchant for light extraction rose (Provencal style). However, if not stored properly these wines can deteriorate very quickly - in direct sunlight the change can occur in a matter of days.

here is how and what you need to know

Lightstrike damage in wine refers to the negative effects of exposure to ultraviolet (UV) light, particularly sunlight, on bottled wine. When wine is exposed to UV light for prolonged periods, it can cause chemical reactions in the wine, resulting in off-flavors and aromas. These reactions can lead to a phenomenon commonly known as "lightstrike" or "lightstruck" wine.

The primary cause of lightstrike damage is the interaction of UV light with riboflavin (vitamin B2) present in the wine. This interaction produces sulfur compounds, such as hydrogen sulfide, which can give the wine unpleasant aromas reminiscent of rotten eggs or burnt rubber.

One study of glass bottles on supermarket shelves, found that lightstrike occured in some wines in clear bottles after just 1-2 days. But all developed them in 20+ days 

On the other hand, volatile sulphur components (stinky stuff) can be formed even within 1 hour of exposure.

To prevent lightstrike damage, winemakers often use colored glass bottles or UV-blocking materials in packaging to shield the wine from exposure to sunlight.

As a buyer its always best to buy from supermarkets/stores which sell products quickly / dont pick the bottle that is at the front of the shelf / ask for one from the carton or box and out of direct sunlight.

You ll be very disappointed to buy an expensive Provencal style Rose - only to find it has been damaged whilst on display.

Another solution could be to buy from e-commerce sellers or wine clubs which dont sell on shelves. Try
