Wisconsin’s challenging climate—with cold winters, short growing seasons, and variable conditions—demands exceptionally cold-hardy grape varieties. Most successful ones are hybrid cultivars bred by the University of Minnesota or Wisconsin’s own Elmer Swenson, combining native American species for winter survival down to -30°F or lower, disease resistance, and reliable ripening. These thrive in zones 3–5 across the state, supporting both commercial wineries and home growers for wine, table grapes, juice, or jelly.
Despite the cold winters, Wisconsin’s summers provide favorable conditions for grape growth. During the growing season, the region usually experiences warm temperatures, long daylight hours, and moderate rainfall. These conditions allow grapevines to produce healthy leaves, flowers, and fruit. Adequate sunlight is particularly important because it helps grapes develop their sugars, flavors, and color as they ripen.
The soil conditions in many parts of Wisconsin also support grape cultivation. Well-drained soils are especially important for grapevines, as they do not tolerate standing water around their roots. Sandy loam and gravelly soils are often ideal because they drain well while still holding enough moisture and nutrients for vine growth. Good air circulation on slopes and hillsides can also help protect vines from frost and certain plant diseases.
Grapes that Grow Well in Wisconsin
Frontenac
Frontenac is a University of Minnesota release (1996) known for exceptional cold hardiness to below -30°F and high productivity. It produces small, dark blue-purple berries in tight clusters that ripen mid-season with high sugar and acidity, yielding bold red wines featuring cherry, black currant, and spice notes—ideal for rosé, dry reds, or ports after malolactic fermentation. Disease-resistant and vigorous, it suits Wisconsin’s short seasons without needing protection, making it one of the most planted reds in the state.
Marquette
Marquette, another UMN variety, stands out for superior cold hardiness (surviving -36°F) and low disease susceptibility, including to mildew and rot. Early mid-season ripening brings medium-bodied red wines with distinctive cherry, black currant, blackberry, pepper, and spice aromas at around 26° Brix. Wisconsin wineries praise it for versatile dry reds or rosés; its open, upright growth and secondary bud productivity make it reliable in the state’s variable springs and sandy soils.
La Crescent
La Crescent offers -36°F hardiness and muscat-like aromatics of apricot, lime, pineapple, and honey with no “foxy” flavor. Bred for northern climates, it ripens reliably for sweet or semi-sweet Riesling-style whites that shine in Wisconsin’s cool conditions. Vigorous vines resist many diseases, and the fruit works for fresh eating or wine; it’s a staple in state vineyards for its flavor intensity and frost tolerance.
Brianna
Bred by Wisconsin’s Elmer Swenson, Brianna is extremely productive and winter-hardy with tight clusters of greenish-gold berries turning gold. Early mid-season ripening delivers semi-sweet white wines bursting with pineapple, grapefruit, and tropical notes (or dry styles with floral hints). High pectin requires enzymes for processing, but its vigor and crown-gall sensitivity aside, it excels in Wisconsin for reliable yields and fruit-forward wines or juice.
Itasca
Itasca (UMN 2017 release) ranks among the hardiest cultivated grapes, surpassing many at -36°F, with low acidity for high-quality dry whites. Yellow-to-straw wines feature pear, quince, melon, violet, mineral, and subtle honey aromas from coppery-peach berries. Released specifically for cold climates like Wisconsin, it ripens well and produces balanced, site-expressive wines without heavy intervention.
Lacrosse
Lacrosse (often spelled La Crosse) is a clean, neutral white hybrid with strong disease resistance suited to Wisconsin’s humid conditions. Late mid-to-late September ripening yields dry or semi-dry wines with a crisp character and good acidity balance. Vigorous and productive, it complements blends or stands alone; its reliability in short seasons and cold tolerance make it a solid choice for Midwest growers seeking versatile whites.
St. Croix
St. Croix provides large, very sweet red grapes on hardy vines (-30°F+ tolerance) that ripen mid-season. Closely related to Sabrevois but slightly less extreme in hardiness, it makes approachable red wines with fruit-forward profiles. Wisconsin growers value its productivity and sweetness for table wines or blending; disease resistance and vigorous growth suit the state’s variable weather without excessive protection.
Petite Pearl
Petite Pearl excels with -32°F hardiness and early ripening, ideal for Wisconsin’s short seasons. Released in 2010, it delivers earthy, spicy red wines perfect for blending or standalone varietals with dark color and berry notes. Wisconsin wineries grow it successfully for its toughness in cool areas; compact clusters and resilience to cold make it increasingly popular.
Sabrevois
Sabrevois is one of the toughest reds for Wisconsin, thriving where others struggle with extreme cold and short seasons. It produces wines with appealing dark color, fruitiness, and nice berry aromas—outstanding for sweet reds or blends. Hardy vines yield reliably; its appeal in too-cool sites and consistent performance have made it a go-to in state vineyards.
Marechal Foch
Marechal Foch (French-American hybrid) offers early ripening and hardiness around -22°F, with very early bud break suited to Wisconsin’s frosty springs. It creates versatile reds, rosés, or ports with Burgundy-like character and herbaceous notes. Low vigor requires careful management, but it performs well in sandy soils; growers use it for quick-maturing, flavorful wines in cooler microclimates.
Edelweiss
Edelweiss, a Swenson/UMN hybrid, is highly productive and hardy to -32°F with large, intensely sweet white-green grapes. Early ripening (mid-August) supports table use, juice, or pleasant semi-sweet wines with labrusca hints when fully ripe. Disease resistance and high juice yield shine in Wisconsin, though thin skins spoil quickly—perfect for fresh eating or quick processing.
Prairie Star
Prairie Star delivers neutral white wines with full mouthfeel and delicate floral notes, hardy to -35°F or lower. Early ripening and vigorous growth make it a reliable blender (adding body to lighter varieties like Louise Swenson) in Wisconsin’s climate. Disease resistance and no need for cluster thinning suit home and commercial growers seeking balanced, non-foxy profiles.
Louise Swenson
Louise Swenson withstands -40°F consistently, with delicate flower-and-honey aromas in high-quality white wines. UMN trials confirm year-to-year reliability in Wisconsin; vigorous vines produce dependable crops needing some irrigation in dry soils. It blends well or stands alone for elegant, light wines—ideal for the state’s harsh winters.
Valiant
Valiant is ultra-hardy (to -50°F in tests) with blue grapes resembling improved Concord—sweet, tangy, and aromatic. Early ripening supports juice, jelly, or light rosé wines; productive vines thrive in Wisconsin’s sandy or northern soils. A step up from Beta, it suits table or processing use where extreme cold limits other varieties.
Reliance
Reliance is a moderately hardy (-15°F to -29°F survival in trials) seedless pink table grape with spectacular fruity flavor and melt-in-mouth texture. Early ripening and 3-month storage make it a Wisconsin trial standout for fresh eating or raisins. Cluster thinning helps; it’s among the most successful seedless options in state evaluations despite some cracking risk.
Somerset Seedless
Somerset Seedless offers cold hardiness to zone 4 with pink-to-red seedless berries that sweeten beautifully. Early ripening and disease tolerance suit Wisconsin’s short seasons for fresh eating, juice, or jelly. One of few reliable seedless cold-hardy table grapes, it performs well in UW trials and home gardens without foxy overtones.
Mars
Mars is a vigorous, seedless blue-black table grape with moderate hardiness (-15°F survival) and slight disease susceptibility. Early ripening (mid-August) yields fruit for table, juice, or jelly; UW trials rank it highly successful in Wisconsin. Cluster thinning prevents overbearing—great for home growers seeking hardy, seedless options.
Bluebell
Bluebell mimics Concord but ripens earlier with greater hardiness (below -20°F) and tender, juicy blue-black skins. Fragrant, candy-like flavor excels for juice, jelly, or fresh eating (short storage); slight mildew tolerance fits Wisconsin humidity. Vigorous and rediscovered by growers, it thrives where true Concord struggles.
