Trollhaugen grapes boast a sweet, floral flavour akin to the esteemed Concord type but with a hardier, thinner skin featuring fewer, undetectable seeds. On average, they weigh 2 grams and range in size from small to medium. When fully ripe, their colour darkens to a deep blue-black hue, with small, dense clusters and a tender, juicy flesh. These grapes are ideal for both eating fresh and drying (e.g. raisins!) and usually ripen in late August to early September. Vines show vigorous growth, with fruit production starting around three years of age. Trollhaugen was developed by Elmer Swenson and released in 2000.
Growers Note: Lay the vines down on the ground in autumn before snowfall. Then cover with leaves and eventually snow as this provides insulation. This is a successful and recommended technique for cold climate grape growing to protect vines from extreme cold. Grapes grow very vigorously on a warm south-facing side of a building and sheltered area.
