6 Surprising Benefits of Red Wine Vinegar
By Lauren Panoff, MPH, RD
Vinegars are made by fermenting a carbohydrate source into alcohol. Acetobacter bacteria then convert the alcohol into acetic acid, which gives vinegars their strong aromas (1Trusted Source).
Red wine vinegar is made by fermenting red wine, then straining and bottling it. It's often aged before bottling to reduce the intensity of the flavor.
Many people enjoy using red wine vinegar in recipes, though it may also have other household uses.
Here are 6 health and nutrition benefits of red wine vinegar.
1. May Lower Blood Sugar Levels
The acetic acid in red wine vinegar and other vinegars may help lower blood sugar levels.
It appears to slow your digestion of carbs and increase your absorption of glucose, a type of sugar, resulting in less glucose in your blood (1Trusted Source, 2Trusted Source, 3Trusted Source, 4Trusted Source).
One study in adults with insulin resistance found that drinking 2 tablespoons (30 ml) of vinegar before a carb-rich meal lowered blood sugar by 64% and increased insulin sensitivity by 34%, compared to a placebo group (1Trusted Source, 5Trusted Source).
When used to make certain dishes, red wine vinegar can lower these foods' glycemic index (GI). The GI is a ranking system that scores how much a food raises blood sugar (7Trusted Source).
One study noted that replacing cucumbers with pickles made with vinegar lowered the GI of a meal by over 30%. Another study demonstrated that adding vinegar or pickled foods made with vinegar to rice lowered the GI of the meal by 20–35% (8Trusted Source, 9Trusted Source).
Acetic acid, a main component of vinegar, may help lower blood sugar levels. Red wine vinegar may also reduce the GI of foods.
2. May Protect Your Skin
Red wine vinegar boasts antioxidants that may fight bacterial infections and skin damage. These are primarily anthocyanins — pigments that give fruits and vegetables their blue, red, and purple colors (10Trusted Source, 11Trusted Source).
A test-tube study determined that the anthocyanin content of red wine vinegar depends on the type and quality of red wine used to make it. Vinegars made with Cabernet Sauvignon tend to offer the most, providing up to 20 anthocyanin compounds (12).
For example, one test-tube study found that resveratrol killed skin cancer cells and significantly slowed new cancer cell growth (15Trusted Source).
Additionally, the acetic acid in red wine vinegar may fight skin infections. In fact, acetic acid has been used medicinally for over 6,000 years to treat wounds and chest, ear, and urinary tract infections (16Trusted Source, 17Trusted Source).
In one test-tube study, acetic acid prevented the growth of bacteria, such as Acinetobacter baumannii, that commonly cause infections in burn patients (17Trusted Source).
Nonetheless, more research is needed to determine the best uses of vinegar for skin care. Any type of vinegar should be diluted with water before being applied to your skin to reduce its acidity, as undiluted vinegar can cause significant irritation or even burns (18Trusted Source).
The acetic acid and antioxidants in red wine vinegar may be therapeutic for bacterial infections and other skin conditions like burns. Still, more research is needed.
3. May Aid Weight Loss
The acetic acid in red wine vinegar may support weight loss.
What's more, it keeps food in your stomach longer. This delays the release of ghrelin, a hunger hormone, which may prevent overeating (23Trusted Source).
In one study, obese adults drank a 17-ounce (500-ml) beverage with 15 ml, 30 ml, or 0 ml of vinegar daily. After 12 weeks, the vinegar groups had significantly lower weights and less belly fat than the control group (24Trusted Source).
In another study in 12 people, those who consumed vinegar with higher amounts of acetic acid alongside their breakfast of white-wheat bread reported increased fullness compared to those who consumed low-acetic vinegar (25Trusted Source).
Red wine vinegar may support weight loss by increasing feelings of fullness and delaying the release of hunger hormones.
4. Contains Powerful Antioxidants
Red wine, the primary ingredient in red wine vinegar, boasts powerful polyphenol antioxidants, including resveratrol. Red wine also contains antioxidant pigments called anthocyanins (26Trusted Source).
The antioxidants in red wine are also present in its vinegar, though in smaller amounts. The fermentation process can reduce anthocyanin content by up to 91% (28Trusted Source).
Red wine vinegar packs powerful antioxidants known to help prevent chronic diseases. However, much of the original antioxidant content in red wine is lost during the fermentation process.
5. May Boost Heart Health
Red wine vinegar may improve your heart health.
Though most studies examine red wine, its vinegar contains the same antioxidants — just in much smaller amounts.
A 4-week study in 60 adults with high blood pressure found that taking red wine extract significantly lowered blood pressure compared to grape extract, which had no effect (31Trusted Source).
Polyphenols like resveratrol in red wine vinegar relax your blood vessels and increase the amount of calcium in your cells, which improves circulation and lowers blood pressure (32Trusted Source, 33Trusted Source, 34Trusted Source, 35Trusted Source).
Acetic acid may have similar effects. Rodent studies indicate that acetic acid lowers blood pressure by increasing calcium absorption and altering hormones that control blood pressure, as well as fluid and electrolyte balance (33Trusted Source).
Acetic acid has been shown to lower total cholesterol and triglycerides in rats. High doses also lowered LDL (bad) cholesterol in rabbits fed a high-cholesterol diet (38Trusted Source, 39Trusted Source).
The acetic acid and polyphenols in red wine vinegar may help lower total cholesterol, blood pressure, and triglycerides, high levels of which may be risk factors for heart disease.
6. Incredibly Versatile
Red wine vinegar is widely used in cooking but may have other applications as well.
It's often an ingredient in salad dressings, marinades, and reductions. Red wine vinegar pairs well with hearty foods like pork, beef, and vegetables.
While white vinegar is often reserved for household cleaning, red wine vinegar may be used for personal care.
For example, you can dilute red wine vinegar with water in a 1:2 ratio and use it as a facial toner.
Additionally, adding 2–3 tablespoons (30–45 ml) of red wine vinegar to your bath along with Epsom salt and lavender may soothe your skin. Some people also find that diluted red wine vinegar helps heal mild sunburn.
Red wine vinegar is most often used in salad dressings and marinades for meat and vegetable dishes. That said, it can also be used for personal care.
Overconsumption Can Have Adverse Effects
Red wine vinegar may have a few downsides.
Daily consumption over several years has been shown to increase your risk of negative effects (40Trusted Source).
For example, drinking too much vinegar can worsen digestive symptoms, such as nausea, indigestion, and heartburn. It may also affect certain blood pressure and heart medications by lowering potassium levels, which can further reduce blood pressure (40Trusted Source, 41Trusted Source).
Additionally, acidic solutions like vinegar may damage tooth enamel, so be sure to rinse your mouth with water after enjoying vinegar-containing foods or beverages (42Trusted Source, 43Trusted Source).
Long-term consumption of red wine vinegar may lead to indigestion and nausea, interact negatively with certain blood pressure medications, and damage tooth enamel.
The Bottom Line
Red wine vinegar has a number of benefits, including lower blood sugar, blood pressure, and cholesterol. As it's derived from red wine, it also boasts a number of antioxidants.
Drinking or using this vinegar in moderation is safe but could be harmful if taken in excess or alongside certain medications.
If you're curious about this versatile and tart ingredient, you can easily buy it in your local grocery store or online.

The COVID-19 pandemic in the United States is the deepest and longest period of malaise in a dozen years. Our colleagues at the University of Vermont have concluded this by analyzing posts on Twitter. The Vermont Complex Systems Center studies 50 million tweets a day, scoring the "happiness" of people's words to monitor the national mood. That mood today is at its lowest point since 2008 when they started this project.
The Hedonometer measures happiness through analysis of key words on Twitter, which is now used by one in five Americans. This chart covers 18 months from early 2019 to July 2020, showing major dips in 2020. hedonometer.org<p>These same tweets also indicate a potential salve. Before pandemic lockdowns began, doctoral student <a href="https://scholar.google.com/citations?user=0P0ZYbIAAAAJ&hl=en" target="_blank">Aaron Schwartz</a> <a href="https://doi.org/10.1002/pan3.10045" target="_blank">compared tweets before, during, and after visits to 150 parks, playgrounds and plazas</a> in San Francisco. He found that park visits corresponded with a spike in happiness, followed by an afterglow lasting up to four hours.</p><p>Tweets from parks contained fewer negative words such as "no," "not" and "can't," and fewer first-person pronouns like "I" and "me." It seems that nature makes people more positive and less self-obsessed.</p><p>Parks keep people happy in times of global crisis, economic shutdown and public anger. Research has also shown that transmission rates for COVID-19 are <a href="https://www.sfchronicle.com/news/article/Is-risk-of-coronavirus-transmission-lower-15287602.php" target="_blank">much lower outdoors than inside</a>. As scholars who study <a href="https://scholar.google.com/citations?user=yFzb2EUAAAAJ&hl=en" target="_blank">conservation</a> and how nature <a href="https://scholar.google.com/citations?user=CCnUeN8AAAAJ&hl=en" target="_blank">contributes to human well-being</a>, we see opening up parks and creating new ones as a straightforward remedy for Americans' current blues.</p>
Park Visits Are Up During the Pandemic<p>According to the Hedonometer, sentiments expressed online started trending lower in mid-March as the impacts of the pandemic became clear. As lockdowns continued, they registered the lowest sentiment scores on record. Then in late May, effects from George Floyd's death in police custody and the following protests and police response once again could be seen on Twitter. May 31, 2020 was the saddest day of the project.</p><p>Recent surveys of park visitors around the University of Vermont have shown people <a href="https://osf.io/preprints/socarxiv/sd3h6" target="_blank">using green spaces more</a> since COVID-19 lockdowns began. Many people reported that parks were highly important to their well-being during the pandemic.</p>

Their impact on happiness is real, measurable and lasting.</p><p>Twitter records show that parks increase happiness to a level similar to the bounce at Christmas, which typically is the happiest day of the year. Schwartz has since expanded his <a href="https://arxiv.org/pdf/2006.10658.pdf" target="_blank">Twitter study</a> to the 25 largest cities in the U.S. and found this bounce everywhere.</p><p>Parks and public spaces won't cure COVID-19 or stop police brutality, but they are far more than playgrounds. There is growing evidence that parks contribute to mental and physical health in a range of communities.</p><p>In a 2015 study, for example, Stanford researchers sent people out for one of two walks: through a local park or on a busy street. Those who walked in nature showed <a href="https://doi.org/10.1016/j.landurbplan.2015.02.005" target="_blank">improved moods and better memory performance</a> compared to the urban group. And a team led by <a href="https://penniur.upenn.edu/people/eugenia-gina-south" target="_blank">Gina South</a> of the University of Pennsylvania showed in a 2018 study that greening and cleaning up blighted vacant lots in Philadelphia <a href="http://dx.doi.org/10.1001/jamanetworkopen.2018.0298" target="_blank">reduced local residents' feelings of depression, worthlessness and poor mental health</a>.</p>
Creative Strategies<p>It isn't easy to create new parks on the scale of San Francisco's Golden Gate Park or the Washington Mall, but smaller projects can expand outdoor space. Options include greening vacant lots, closing streets and investing in existing parks to make them safer, greener and shadier and support wildlife.</p><p>These initiatives don't have to be capital-intensive. In the University of Pennsylvania study, for example, renovating a vacant lot by removing trash, planting grass and trees and installing a low fence cost only about US$1,600.</p><p>Urban green space is most needed in neighborhoods that have lacked funding for parks, especially given <a href="https://www.nytimes.com/2020/04/08/nyregion/coronavirus-race-deaths.html" target="_blank">COVID-19's disproportionate impact on Black and Latinx people</a>.</p><p>Cities can also create parklike spaces by <a href="https://theconversation.com/with-fewer-cars-on-us-streets-now-is-the-time-to-reinvent-roadways-and-how-we-use-them-140408" target="_blank">closing streets to cars</a>. Many cities worldwide are currently retooling their transportation systems for the post-COVID-19 world in order to <a href="https://thecityfix.com/blog/bicycles-slower-speeds-livable-city-paris-mayor-anne-hidalgo-plans-ambitious-second-term-dario-hidalgo/" target="_blank">reallocate public space</a>, widen sidewalks and make more space for nature.</p><p>Urban designers, artists, ecologists and other citizens can play a direct role, too, creating pop-up parks and green spaces. Some advocates <a href="https://www.bloomberg.com/news/articles/2017-09-15/a-brief-history-of-park-ing-day" target="_blank">transform parking spaces into mini-parks</a> with grass, potted trees and seating for just the time on the meter, to make a larger point about turning so much public space over to cars.</p><p>Or cities can invest a little more. Minneapolis, Cincinnati and Arlington, Virginia, have won <a href="https://www.tpl.org/parkscore" target="_blank">national recognition</a> for their ambitious investments in public park systems. These areas could serve as models for neighborhoods that lack access to parks.</p>
