Fall is here!!

A recipe we are perusing calls for 2 1/2# chokecherries and 1 # raisins or
1/2 pint red grape concentrate per gallon.
We'd appreciate hearing if either would work better. Being in the middle of
nowhere with the nearest supplier of winemaking goods about 400 miles away
the raisins would sure be easier.
Just wondering if the raisins wouldn't be overpowering as far as it's own
flavor.

Thanks

Mark
