For well over a century, families have been enjoying the goodness of the Concord grape as Welch’s 100% Grape Juice. But, it's only been in the last 20 years or so that scientists have uncovered just how super this superfruit is for health.
Read on for more on the research-backed benefits of 100% grape juice made with Concord grapes:
Decade’s worth of research says that, thanks to the dark purple Concord grape and its polyphenol power, 100% grape juice can help support a healthy heart. In fact, Concord grapes and their juice deliver many of the same polyphenols and heart health benefits as red wine.
One of the key ways that 100% grape juice supports heart health is by promoting healthy circulation, keeping your blood pumping and energy flowing. To read more about the science linking 100% grape juice to heart health and healthy circulation, visit grapescience.com.
While more research is definitely needed, early science says that the polyphenol-powered Concord grapes in 100% grape juice may benefit cognitive performance in both older and younger adults.

Two small studies have shown that drinking Concord grape juice vs. an added sugar, low-polyphenol drink (placebo) improves memory function in older adults with age-related memory decline.1,2 In one of those studies, the researchers used a technique called functional magnetic resonance imaging (fMRI) to look at specific areas of the brain.2 What they found was that the grape juice drinkers had increased blood flow in two regions of the brain linked to memory, when compared to the placebo drinkers. Although more science is needed, this suggests that 100% grape juice’s circulation benefit may help keep your heart and your mind healthy.
Attention, Reaction Time & Mood:
Researchers from the UK discovered that Concord grape juice enhanced cognitive function in people with busy, stressful lifestyles – specifically working moms of pre-teens.3 During this study, 40-50 year old women participated in a series of brain-bending tasks, including a driving simulator challenge. Mom drivers that drank the grape juice for several weeks (vs. a low-polyphenol drink), were more attentive and quicker to react behind the wheel. These learnings were reinforced with a second small study, which found that drinking a daily serving of 100% grape juice made with Concord grapes (vs. a low-polyphenol drink) had an immediate, positive impact on both mood and attention in young adults (mean age of 21 years).4
Immune System Health
Eating a nutritious diet packed with colorful fruits and veggies helps ensure you’re getting an array of vitamins, minerals and beneficial plant nutrients (i.e. polyphenols) for health. Welch’s 100% Grape Juice delivers the power of purple fruit and antioxidants, like polyphenols and vitamin C.
What’s more, one study found that healthy adults who regularly drank Welch’s 100% Grape Juice (vs. a low-polyphenol drink) saw an increase in a specific type of immune cell called the gamma delta T-cell.5 This “watchdog” immune cell plays an important role in the body - detecting potential invaders and alerting the immune system to respond. While this research is preliminary, it builds on earlier laboratory studies and suggests the antioxidants in 100% grape juice may help support a healthy immune system.
