Wine Hangovers No More? Way Found to Rid Vino of Headaches

Wine hangovers will soon be a thing of the past, as scientists have discovered a way to make it healthier and reduce harmful components via genetic engineering.

University of Illinois scientists revealed their development of a so-called "genome knife" in the journal Applied and Environmental Microbiology this week. The "knife" was developed as an enzyme (RNA-guided Cas9 nuclease).

With the new technology, scientists now have the ability to tinker with polyploid strains of yeast – a key component of fermented foods like wine, beer, and bread.

That ability to tinker on the genetic level means that they can now do things like ramp up the percentage of wine's healthy components, such as resveratrol – which is good for heart health.

"With engineered yeast, we could increase the amount of resveratrol in a variety of wine by 10 times or more," said the study's lead author, Yong-Su Jin.

"But we could also add metabolic pathways to introduce bioactive compounds from other foods, such as ginseng, into the wine yeast. Or we could put resveratrol-producing pathways into yeast strains used for beer, kefir, cheese, kimchee, or pickles – any food that uses yeast fermentation in its production."

In addition to increasing wine's healthy components, scientists say they can also reduce harmful ones, such as those produced in the second fermentation statge, malolactic fermentation.

"We envision that our yeast engineering technology can get rid of the secondary fermentation step – and therefore the headache-contributing allergens – while still making wine taste smooth," Jin explained.

According to Shape magazine, the technology is still under development, but there are a number of things one can do to avoid wine headaches in the meantime.

"To avoid a wine headache, opt for white over red (the lighter variety doesn’t keep the skin on the grapes during fermentation), varieties aged in stainless steel over oak (for less irritating compounds from the storage vessel), fruity flavors over buttery (the latter of which are traditionally aged in oak), and with lower alcohol content," the magazine recommends.
