Somerset is self-fruitful — per University of Maryland Extension, most seedless table grapes, including this one, set fruit from their own pollen, so you don't need a second variety nearby just to get a crop.
Plant in full sun — morning sun especially, since it dries the foliage faster and cuts down on disease pressure. Well-drained soil with a pH of 5.5–6.5 is ideal, spaced roughly 8 feet apart with something for the vine to climb.
Worth knowing before you plant: grapevines need hard pruning every single dormant season — about 90% of the previous year's growth gets removed — and the first real harvest is usually 3 years out. It's a longer-term planting than most fruit shrubs, but a well-maintained vine produces for decades.
