On the last Thursday of August, the quiet countryside of Pearl River County, Mississippi, turns into a classroom without walls. More than a hundred people wander down rows of low, heavy-laden grapevines at the McNeill Research Unit outside Carriere, tasting fruit that varies in flavor, skin thickness, and seed size among different cultivars. That is the annual Muscadine Field Day, a free, late-August tradition in south Mississippi, and its 2026 edition is set for Thursday, Aug. 27, with on-site registration beginning at 8:30 a.m. and a program running from 9 to 11 a.m. at the station at 7 Ben Gill Road, across the highway from Jack's Fish House.
The field day is co-hosted by the Mississippi State University Extension Service, the Mississippi Agricultural and Forestry Experiment Station, and the U.S. Department of Agriculture's Agricultural Research Service, and it is organized by Eric Stafne, an Extension and research professor who specializes in small crops such as muscadines, grapes, and blueberries. The event is free and open to commercial and hobby producers alike. "One thing about muscadines is that it's a very unique fruit, and if you're not familiar with it, the idea behind this event is that you can come and taste it," Stafne said. "You can see what it looks like and, surprisingly -- or maybe not surprisingly -- a lot of the cultivars have very different flavors."
The morning opens with a series of talks, with speakers from all three co-hosting organizations weighing in on the specialty crop. This year's menu includes a look at newly arriving leafhopper pests, guidance on selecting muscadine cultivars for success, and the practical business of insect and disease management. There are also demonstrations of winemaking equipment, a chance to explore passion fruit, a primer on pesticide modes of action, and a discussion of transitioning to an organic program. Then, around 10 a.m., the classroom moves outdoors: guests are sent into the vineyard to collect and taste the fruit themselves.
Muscadines deserve the attention because they are a native grape species of the region, thriving in the very soil where the field day is held. They are also, in many ways, easy partners for the homeowner and the small farmer. Because they are native to the Southeast, they face minimal disease and pest issues and can often be grown without the need for sprays. That makes them well suited to the do-it-yourself backyard grower, and the goal of the field day is to educate homeowners interested in small-scale vineyards.
The vines themselves live on a piece of land with an even deeper history. The McNeill Research Unit, about 397 acres spread by McNeill Steephollow Road and Ben Gill Road along Highway 11, traces its roots to a branch experiment station established here more than a century ago. Early reports from the station, published in the nineteen teens and twenties, describe clearing cut-over pine lands, building pastures, and raising cattle -- an operation that today now turns its attention to research on muscadines, bunch grapes, ornamentals, wine making, forage, and even termite research. The station's vineyard also has a long history of association with USDA research, primarily focusing on muscadines.
Now this partnership is part of what makes the field day feel especially forward-looking. Attendees will hear about the Vitis x Muscadinia, or VxM, research project, a national effort in which Mississippi State University is one of 13 universities across the U.S. that have partnered for the project, which is focused on developing a hybrid grape for quality and disease resistance. If it succeeds, the payoff could be a more resilient American grape industry.
The field day also makes the case for just how much variety hides inside one plant. Many muscadine cultivars grow at the McNeill Unit, and their differences go far beyond color: skin thickness varies, seed size varies, and the flavor range can be astonishing, a point Stafne likes to make by handing out samples. The event now regularly draws more than 100 participants each year, and it has been held for the past fifteen years -- a working farm that opens its gates each August to a thirsty public.
There is no charge to attend, and no advance sign-up is required -- just show up at 8:30 in the morning, bring water and chairs, and expect to spend the morning with scientists, farmers, and a grape native to the region. At the end of it, everyone goes home with a taste of the fruit and, often, an itch to plant a vine of their own. For more information, contact Eric Stafne at [email protected] or call 662-769-9708.
