Global warming is affecting your beloved glass of wine

A new study shows that an increase in temperatures has a knock-on effect when it comes to wine.

If rising sea levels and soaring temperatures weren’t reason enough to make you care about global warming, this one might make you sit up and take note.

We hate to break it to you, wine-lovers, but the expanding hole in our ozone layer is messing with your beloved Sauvignon Blanc and Chardonnay.

According to the findings of the study, published in the journal Temperature, people working in vineyards won’t be able to work the same number of hours as before, due to the beating sun.

The obvious result of this is fewer litres of wine. The cost of labour will also shoot through the roof as potential health-risks of toiling under the blazing sky increases.

“Climate change may have also increased the heat exposure in the subtropical areas, where the majority of the wine is produced,” researchers wrote in the journal, which was published last week.

“This is noteworthy because wine production is still dominated by manual work.

“However, given the increase in environmental temperature during the past five millennia, the workers who currently pick the grapes carry out their jobs under adverse environmental conditions.”

And because the production will be more expensive, the price per bottle will also most likely increase considerably.

As if forking out a lot more cash for your favourite bottle of red wine isn’t enough, bear in mind that previous research has shown that heat affects the taste of wine.

Not only does it have an impact on how and when grapes ripen, it interferes with the balance between sugars and acidity.

Poor-tasting wine and a once-beautiful planet in a dire state?

More than enough reason to tighten the greenbelt, we reckon.
