Riesentraube

German heirloom variety grown by Pennsylvania Dutch as early as 1856. Name translates as "giant bunches of grapes." Produces tasty fruits in clusters of 20-40 and each distinctly pointed. To say that this variety is productive is an understatement. Round 1" fruit has a distinct nipple on the blossom end.  Indeterminate, 80 days from transplant.

Blondkopfchen is a yellow match with a nipple also. Both originally came from the German seed bank.
