In 2022, Italian researchers discovered that inside seven days of storing white wine in glass bottles the quantity of terpenes, compounds which add floral and fruity notes corresponding to lilac and blueberry to a wine, had diminished by as much as 30 per cent, whereas norisoprenoids, that are answerable for advanced woody notes, declined by 70 per cent.
The similar wines saved in darkish bottles for 50 days confirmed no deterioration, the researchers discovered.
Mr Richards stated: “Marketeers say people want to see the wine before they buy it, particularly with rose because it’s bright and pretty, but this desire is ironically contributing to its lack of quality.”
Ms Barry added: “The science is literally telling us this is an issue, and yet you can’t buy a single still rose wine in a supermarket that’s not in a clear bottle.
“There’s not even a choice. You could easily have those wines in dark glass bottles, or bag-in-boxes, or cans, frankly, maybe with a picture of the wine colour.”
The results of sunshine strike should not reversible, the couple added, calling the problem “daylight robbery” due to the diminished high quality product individuals can find yourself paying for.
Ms Barry stated the dimensions of the issue is probably going far larger than “any other wine taint, and yet we don’t really talk about it”.
She added: “By and large we accept it, sometimes we inadvertently embrace it, and mostly we just carry on pretending it’s not an issue, while it’s effectively depriving us all of our rightful enjoyment of wine. It is daylight robbery in every sense of the term.”
