The white grape variety (also called Inkameep Riesling) is a descendant of the American wild grape Vitis labrusca. However, some Canadian grape specialists believe that it is an interspecific cross between Vitis berlandieri x Vitis riparia. It has nothing to do with the German Riesling, the name has not been allowed to be used since 1999 according to an international agreement. According to this, the hybrid was crossed in Hungary, where it was allegedly used by Sigmund Teleki (1854-1910) for breeding rootstocks. The late-maturing, frost-hardy vine produces white wines with a light muscatel tone. It was named after the Okanagan Valley in British Columbia (Canada), where it is now only grown on half a hectare. Further vineyards are to be found in the northwest of the USA and in New Zealand. In 2016, however, only the stock in Canada was reported (statistics Kym Anderson).
There is a vast number of sources on the web where one can acquire knowledge about wine. But none has the scope, timeliness and accuracy of the information in the encyclopaedia at wein.plus. I use it regularly and rely on it.
