Mushroom Management is the last thing any organisation wants to be accused of practicing. However, being kept in the dark is great if you are a wine. For wine, light damage is a very real threat.
Premium wines, that are intended to be stored, are usually contained in tinted or coloured bottles. Darker coloured glass prevents light in the ultraviolet (UV) spectrum from breaking down elements of the wine that are desirable. Wines that are intended to be consumed soon after bottling often go into clear glass bottles. After all, hopefully they won’t be around long enough to get light damaged!
Shockingly, the group that produce the Wotwine app are claiming that over a third of the wines stored in clear glass bottles, from some 6,000 wines they sampled in the last two years, had suffered light damage.
Remarkably, they also claimed that around 4% of the wine they purchased from supermarkets was light damaged. If true that would be far more prevalent than cork taint, which is thought to only affect around 1% of bottles.
Their reasonable theory is that the fluorescent lighting prevalent in supermarkets often is of a wavelength close to UV, and hence may damage wine within a few hours of it being on the shelf.
Their advice is to pick up a bottle from within the wine aisle and to avoid bottles on aisle ends as these are more likely to be light damaged.
Of course, once you have purchased your wine, no matter where you got it, keep it a cool dark place until you are ready to drink it.
