my grapes are not grapey when distilled

[runingkind]

I just run my grape wash.I ended up with about a three gallon wash.I let it ferment till airlock stoped bubbling.I racked it twice and made sure no nastys
left in it.I run once thru pot still.Collected till no taste of alc.Clear as glass but no grape flavor.Havn't run second time yet or checked abv.Should I run it again or throw it in with my next run,Can't figure why I got no flavor at all not even a hint of it.As allways thanks for the feedback
