Can Drinking Champagne Really Save Your Memory?

The results of a 2013 study on champagne and memory resurfaced this week, prompting bottle-popping celebrations across the Internet. Drinking champagne, it was claimed, is good for your brain and can reduce dementia risk, giving us all a scientific reason to break out the bubbly.

Unfortunately, it’s just not true. The 2013 study was focused on champagne and memory, but the results were nowhere near clear-cut.

Much of the hype stems from a press release sent out by the University of Reading at the time of the paper’s publication in the journal Antioxidants and Redox Signaling. The release states that “drinking one to three glasses of champagne a week may counteract the memory loss associated with ageing, and could help delay the onset of degenerative brain disorders, such as dementia.”

Nope, nope, and nope. First of all, there’s a big gaping omission in this story: the species of the research subjects. The scientists tested the effects of champagne on rats, not people. We have no idea if these effects might translate to human brains.

Secondly, there was no proof that champagne helped more than any other alcoholic beverage. The 24 rats in the study were divided into three groups. Eight got champagne, eight got another alcoholic drink, the final eight were given a non-alcoholic fizzy drink. All three groups were then led through a series of tasks to test their spatial memory. It’s true that the champagne-swilling rodents did better than those who stayed sober, but they didn’t fare any better than the non-champagne-booze group. In other words, there’s no proof that champagne has super memory-boosting powers.

Finally, the ability of champagne to stave off dementia was never even tested.

So what did the study prove? Not much. It showed that the spatial memory of older rats can improve with moderate alcohol consumption—but even these results have yet to be replicated.

Like any other science, the research surrounding the effects of alcoholic beverages is constantly evolving and full of contradictions. Some studies say drinking in moderation is beneficial; others say it’s dangerous.

The bottom line: There’s no evidence whatsoever that upping your Cristal consumption will save your brain. But let’s be serious. Since when did you need an excuse to drink champagne?

Is There Any Point in Letting Red Wine Breathe?

by Aliya Whiteley

At the end of a long day, few things beat simple pleasures like watching a good film, eating a bar of chocolate the size of your head, or drinking a big glass of red wine.

By this point in the evening, most people don’t want to be told that they need to uncork the bottle and let the wine sit for at least 30 minutes before it becomes pleasantly drinkable. Yet that's (by the letter of the unwritten law) what you're supposed to do.

But why? Well, let's start with the assorted historical reasons.

Red wine has been around since the Stone Age. In fact, in 2011 a cave was uncovered in Armenia where the remains of a wine press, drinking and fermentation vessels, and withered grape vines were uncovered; the remains were dated at 5500 years old. Early winemaking often had a ritualistic aspect: Wine jars were found in Ancient Egyptian tombs, and wine appears in both the Hebrew and Christian bibles.

The concept of letting wine "breathe" is, historically speaking, relatively new and probably has its roots in the way wine was once bottled and stored.

Traditionally, sulfur is added to wine in order to preserve it for longer, and if too much is added the wine might well have an ... interesting aroma when first opened—the kind of "interesting aroma" that bears more than a passing resemblance to rotten eggs. Contact with the air may have helped to remove the smell, so decanting wine may once have been a way of removing unwelcome odors, as well as getting rid of the sediment that built up in the bottom of bottles.

It’s also possible that the concept springs from the early 1860s, when Emperor Napoleon III asked Louis Pasteur to investigate why so much French wine was spoiling in transit. Pasteur published his results, which concluded that wine coming into contact with air led to the growth of bacteria, thus ruining the vino. However, small amounts of air improved the flavor of the wine by "aging" it. In bottles, with a cork stopper, the wine still came into contact with a small amount of oxygen, and by storing it for years the wine was thought to develop a deeper flavor.

However, how much of that actually matters today?

Many experts agree that there is no point in simply pulling out the cork and letting the wine sit in an open bottle for any period of time; the wine won’t come into enough contact with oxygen to make any difference to the taste.

However, decanting wine might still be a useful activity. The truth is this: It entirely depends on the wine.

Nowadays we don’t really age wine anymore; we make it with the aim of drinking it quickly, within a year or so. But some types of wine that are rich in tannins (compounds that come from the grape skins and seeds) can benefit from a period of time in a decanter, to soften the astringent taste. These include wines from Bordeaux and the Rhône Valley, for instance.

If you really want to know if a particular wine would benefit from being given time to breathe, try your own experiment at home. Buy two bottles, decant one, and let it breathe for an hour. Do you notice a difference in the taste? Even if you don’t, it's an experiment that justifies opening two bottles of wine.

One word of warning: No matter where a wine comes from, it is possible to overexpose it to oxygen. So remember Pasteur’s experiments and don’t leave your wine out of the bottle for days. That, friends, would be one hell of a waste.

A Beer From the Middle Ages Is Making a Serious Comeback

Hop-forward beer is all the rage today, but in the middle ages many imbibers preferred brews that skewed towards the sweeter side. Now, centuries after it fell out of fashion, Atlas Obscura reports that gruit ale is making a comeback.

Gruit beer is any beer that features botanicals in place of hops. The ingredients that give the drink its distinctive sweet, aromatic taste can be as familiar as ginger and lavender or as exotic as mugwort and seabuckthorn. The herbs play the role of hops by both adding complex flavors and creating an inhospitable environment for harmful microbes.

It may be hard for modern beer lovers to imagine beer without hops, but prior to the 16th century gruit was as common in parts of Europe as IPAs are in hip American cities today. Then, in 1516, that style of beer suddenly vanished from pint glasses: That was the year Germany passed a beer purity law that restricted beer formulas to hops, water, and barley. Many of the key botanicals in gruit beer were considered aphrodisiacs at the time, and the rising Puritan movement helped push the brew further into obscurity.

Hops have dominated the beer scene ever since, and only in the past few decades have microbrewers started giving old gruit recipes the attention they're due. In 2017, the Scratch Brewing Company in Illinois released their seasonal Scratch Tonic, made from a combination of dandelion, carrot tops, clover, and ginger. The Põhjala Brewery in Estonia brews their Laugas beer using Estonian herbs, caraway, and juniper berries. Get in touch with your local microbrewery to see if they have their own version of the old-school beer in their line-up.
