Also Isabella is related to Kyoho, you could research the varieties to find other related types too with similar flavours.

Kyoho grapes.................
The variety was first produced by the Japanese viniculturist Yasushi Ohinoue in the 1930s and 1940s by crossing Ishiharawase and Centennial grape varieties (Vitis vinifera × Vitis labrusca).[2][1][3] Kyoho is a tetraploid grape variety, as its breeding parents, ‘Ishiharawase’ and ‘Centennial’ are tetraploid bud sports of ‘Campbell Early’ (V. labruscana) and ‘Rosaki’ (V. vinifera), respectively.[4] Like the Concord, Kyoho is a slip-skin variety, meaning that the skin is easily separated from the fruit. The seeds are bitter and the skin is not traditionally eaten. The grape maintains some of the flavor qualities of the Concord, known to consumers from the flavor of most grape jellies and Concord grape juice.[5]

Kyoho grapes were first produced in 1937 in Shizuoka Prefecture, but were not given their present name until 1946.

So you could research the grapes that are the parents of the Kyoho variety.
Also you could google search all the grapes on the list I linked above to find out more info. You can also go by the names on the list as some are Japanese words.
Isabella might be available elsewhere as it is similar to Kyoho, but from America.
For online purchases etc, I use paypal or a seperate debit card with limited $ balance in it.

I dont think anyone ejse has such a collection of grape varieties for sale. There are Kyoho grape farms, and some other nurseries sell it but not the other types.
