Most grape vine varieties have deep root systems—some will go down 20 feet! So, ideally, you would plant them where their roots won’t be thwarted; a raised bed might be too shallow. As for a type to grow, go with an American variety like Concord, Delaware, Nimrod, Mars, or Sunbelt. Though grapes are not especially fussy when it comes to soil, they do not tolerate consistently boggy soils so consider amending your clay-heavy soil.
