Grapes

Somerset Seedless

Mid-August. Reddish Pink, medium-sized seedless grpe with a strawberry-like flavor. Developed in Minnesota. Hardy and moderately vigorous. Zones 4/5-8.

Van Buren

Mid-September.  Concord type purplish black fruit. Very sweet, slip skin. Grows in poor soil. Zones 4-8.

Swenson White

Late September. White Grape with extra fruity flavor. Thick skinned, has good disease resistance. High brix. Vigorous and hardy to -30F. Zones 3/4-8.

Niagara

Late August/Early September.  A popular, sweet, and tangy white grape variety, a cross between Concord and Cassady grapes, known for their use in juice, jams, jellies, and wines, and are also enjoyed fresh. Vigorous and productive, requiring support like trellises, arbors, or fences.  Zone 5-8.

Concord Seedless

Mid-September. Dark Blue Some say the seedless version is unrelated to Concord, and the flavor far surpasses the seeded version. The fruit is small, but excellent to eat fresh. We can't imagine wasting a single one of these grapes on pie or juice, but if you have a bumper crop they are excellent for those uses. Zones 4-9.

St. Croix

September. Blue/Red Medium to large fruit with high sugar content. No as suitable for dessert but highly sought for wine and juice. Extremely hardy and productive. Vines hardy to -40 degrees. Good choice for cold tolerance if needed. Zones 3-8.

Concord 

Late September. Blue. A well known standard for home use and juices. Vigorous and hardy vines. Still the most popular juice variety. Zones 4-8.
