The fruit

The Somerset grape has a complex flavour. While some people detect a hint of strawberry in it, all agree that it is very sweet and extremely delicious, superior in taste to the table grapes one finds at the grocery. It also makes a fantastic juice. The grape starts out light pink with a delicate flavour in late August and darkens as it continues to ripen until early to mid September, gaining sweetness. When completely ripe, it will measure between 19.5 and 20 Brix.

The size of the individual grape is rather small compared to what is available in the grocery store (weighting 1.5 to 2g on average) but the cluster is compact and quite big, averaging 150g. The skin is tender and adherent to the fruit.

While it is called seedless, there are actually seeds if you search for them, but they are soft and hardly noticeable when eating. If you can only plant one grape vine, we suggest this one with no hesitation.

The grape vine

The vine is disease resistant, of average vigour and very productive. It is quite hardy, withstanding temperatures down to -35 C with no damage. The vine has a procumbent growth habit, meaning that it tends to grow towards the ground, so it needs to be trellised. The grape vines you buy are 2 year old plants.

Its origin

Elmer_SwensonSomerset was bred by Elmer Swenson in Wisconsin. Swenson was a pioneer in the breeding of cold-climate table grapes and brought us most of the cold hardy varieties that we have today. Somerset is a cross between ES 5-3-64 and Petit Jewel and has Thompson seedless has one of his grandparents.
