| Variety | Hardiness | Parentage | Description |
| Beta | E-V | Concord X Vitis riparia | Blue slipskin, small, tart, best used for jams and jellies. Extremely hardy, vigorous, and disease resistant. Ripens mid-September. |
| Bluebell | V | Beta X Unknown | Medium size blue slipskin, good for fresh eating, juice and jelly. Ripens early September with Worden. Sweeter and larger than Beta and Valiant. |
| Fredonia | M | Champion X Lucille | Blue slipskin, large, excellent for juice, fresh eating and wine. Similar to Concord but 2 weeks earlier. |
| Frontenac | V | Vitis riparia X
French hybrid Landot 4511 |
One of the hardiest wine grapes bred to date. Fruit quite small, produced in large, loose clusters. A good grower with marked resistance to most common grape diseases. Makes an excellent red wine. |
| Frontenac Gris | V | Vitis riparia X
French hybrid Landot 4511 |
Originating from a bud mutation of Frontenac, this grape is essentially identical to it except for its color. It is pink-white instead of red. Produces an excellent white or blushed white wine. |
| Kay Gray | M | Open Poll. Seedling of 217 (Minn. 78 X
Golden Muscat) |
White slipskin, good for fresh eating and juice. Very disease resistant. Matures late August. Juicy and sweet, low acid. Good for homemade wine, but commercial winemakers have difficulty clarifying it. |
| King of the North | E-V | Wild seedling | Medium to large blue slipskin Concord-type grape. Produces tight clusters of sweet fruit good for fresh eating and juice. An incredibly vigorous grower, producing 5-6 times more growth per year than any other in this climate. Establishes quickly; fruits at a young age. |
| LaCrescent | V | MN 1166
St Pepin X ES6-8-25 |
One of the best white wine selections from the Univ. of MN breeding program. Loose clusters of fruit turn a golden brown when fully ripe. The fruit's delicious apricot-like flavor is imparted to wines. |
| Louise Swenson | E-V | ES 48-33 | One of Elmer's hardiest selections, Louise makes a very fine white wine. May also be used as a table grape. |
| Prairie Star | V | ES 2-7-13 X ES 2-8-1 | One of the new Swenson crosses, possibly even hardier than Frontenac (to -40 degrees F.) Small to medium white grape, excellent for fresh eating and for wine. Produces a non-foxy, full-flavored wine; often used in a blend to fortify thinner white wines. Ripens mid-September. |
| Sabrevois | V | (MN 78 X Siebal) X
(MN 78 X Seneca) |
Produces medium-size clusters of dark, nearly black, berries that make a high qulaity red wine. One of the most vigorous and hardy of the Elmer Swenson crosses out of MN. |
| St. Pepin | V | Seyval X
(MN 78 X Seneca) |
White slipskin with good disease resistance and exceptional vigor. Fruit has good dessert quality. Makes good white wine and pink juice. Needs winter protection in cold areas. (Hardy to -25 degrees F.) |
| Swenson Red | M-P | Minn. 78 X
Seibel 11803 |
A dark red non-slipskin grape; very disease resistant. Keeps well in cold storage. Excellent for fresh eating with thin skin and a meaty texture. Also makes a nice red wine. |
| Swenson White | M-P | ES6-1-43 | Medium-large clusters ripen to a yellow, thick-skinned fruit, excellent for white wines. The fruit ripens late and has a "flowery" taste. Very disease resistant. |
| Valiant | E-V | Fredonia X Vitis riparia | Blue slipskin. Recent research has shown Valiant to be even hardier than Beta, although it is not quite as disease tolerant. The berries are slightly larger and borne in larger clusters than Beta, and are lower acid, but otherwise similar. A vigorous grower. |
| Worden | V | Open Poll. Concord | Blue slipskin, Concord type. Excellent for juice and fresh eating. 2-3 weeks earlier than Concord. Almost never needs winter protection. Grapes hang onto stem better than Fredonia but are not quite as sweet. |
