Black Grapes on a White Grape Vine - What Causes This?

Hi
I'm new to grape vine growing but a vine I bought as a lakemont seedless has just borne fruit in its second year that is red and has seeds!. Apart from the obvious can anyone suggest what might be causing the problem?. Bye the bye my opal plum tree has just developed huge purple fruit, nothing like it should be. Could I have a soil problem? Thanks for any advice. :(

Sounds like you have had some failures of top scions...

Opals are a medium size plum. Cropping around two to three weeks before main crops like Victoria. They are self fertile so often need heavy thinning or they can over crop which can lead to broken branches and bi-annual cropping.
The plums are a red to pale purple colour but they do go dark when they are over-ripe.
