Scientists create ‘supergrapes’ to combat fungal attack on vineyards

Growing vines that are impervious to rot or any parasites is surely the dream for wine makers. And now, scientists in France have made that dream a reality by creating four supergrape varieties that they say need almost zero pesticides.

However, traditional vineyard owners say that the supergrapes could lead to lesser quality ‘Frankenstein’ wine in the future. This is because they mix grape genes from different regions and grow the creation in labs, therefore diluting the purity.

Visually identical

The white and red grapes currently growing at the National Institute of Agronomical Research in Colmar, France, look just the same as any other you’d see in the region. But they’re very different.

They’re grown the lab as part of an ongoing programme named “Resdur”, which aims to create grapes that are “durably resistant” to any kind of fungi, including the two that can destroy whole crops: powdery and downy mildew

Over the last few months, scientists at Inra have been given permission by the state to grow four different supergrapes. Named Araban, Floreal, Vidoc and Voltis, wines made from then will be bottled next year and in 2020.

Decades-long research

Growing grapes that are resistant to rot isn’t a new idea. First attempts to do so started in the 1970s when scientists singled out a resistant gene. Since then, Inra has identified three more by crossing European, Asian and American grapes.

The man in charge of Inra is called Didier Merdinoglu. He says that the grapes will allow winemakers to reduce pesticide use by up to a whopping 90%: “We are talking about dropping from an average of 15 treatments per year to one or two, above all to kill off other diseases and parasites.”

Environmental breakthrough

As 20% of all pesticide use in France is concentrated onto vineyards, even though wine grapes consist of just 3% of the country’s crops, researchers say that these new grapes could be an environmental breakthrough. It will also make growing grapes cheaper for the owner.

France is under increasing pressure to reduce pesticide use fast, after a number of cancer cases among vintners. However, some winemakers remain resistant to the idea of a supergrapes.

They say that grapes grown in the lab could decimate centuries of careful growing traditions that have melded European crops with the local soil, producing subtly different varieties of wine. They say that replacing cultivated grapes with cheaper, much more robust but artificially cultivated ones will mean wine lacks the quality and flavour of the existing regional varieties.

Not GM

These grapes aren’t genetically modified, but purists worry that crossing over different varieties from around the world will lead to “artificial and unnatural ‘Frankenstein wine’”. One said: “This is like crossing a monkey with a man: it may be technically possible, but it goes against nature.”

While that may well be hyperbole from a traditionalist, France must lower pesticide use somehow and it’s likely that this will be the fastest way to hit their targets.

Is it possible to Drink Wine without Getting a Hangover?

Is it possible to drink wine without getting a hangover? We’ve all woken up to find we’ve come down with a bad case of wine headache before. Wouldn’t you love it if you could sup your favourite tipple all night and wake up feeling fresh as a daisy? Well the Ideal Wine Company has discovered that soon, you may be able to do just that.

What happens when you indulge in too much wine?

The Ideal Wine Company provides fine wines from every corner of the planet that you’re destined to love; all for very reasonable prices. We have a passion for our product. We have to in order to ensure we only select the most luxurious of wines for your purchasing pleasure.

Yet even we admit that all wines have one downside. If you indulge in it too much you can wake up with a nasty headache. What would you say if we told you that you may be able to enjoy as much wine as you want without having to fear the consequences? You’d probably laugh and tell us we’re crazy, but soon you may be able to do exactly that.

Scientist develops a way to eliminate ‘toxic’ element in wine

According to the Telegraph, a professor at the University of Illinois has found a way to eliminate the ‘toxic’ element in your favourite bottle that causes hangovers.

Professor Yong-Su Jin has developed a technique that alters the way yeast produces. Yeast is a vital part of the wine-making process. His team has discovered that if you change the DNA of yeast you can increase its nutritional elements, whilst reducing the toxic by-products that are known to facilitate hangovers.

“Genome knife” rids wine of hangover-inducing by-products

Jin recently explained: “Fermented foods such as beer, wine and bread are made with polyploid strains of yeast, which means they contain multiple copies of genes in the genome. Until now, it’s been very difficult to do genetic engineering in polyploid strains because if you altered a gene in one copy of the genome, an unaltered copy would correct the one that had been changed.”

Basically he and his team developed an enzyme known as a “genome knife.” Jin went on to suggest that the “knife” can slice through every copy of the gene and prevent the automatic corrections from happening, which prevents you from getting a hangover.

Yet the “knife” also has another purpose. It can be utilised to clone the enzyme that enhances malolactic fermentation. This is a fermentation process that determines the style and character of a bottle of wine. Jin commented that this can help eliminate hangovers as “improper malolactic fermentation generates the toxic by-products that may cause hangover symptoms.”

Drink in moderation

Therefore yes, soon it may be possible to drink wine without waking up with a hangover the next day. However a hangover-proof bottle of wine is unlikely to make it into your cellar anytime soon. For now, it may be best to stick to drinking in moderation!
