more silly questions...

[newtowine]

regarding the grapes at the grocery store(red&white)...what kind are they? have they ever been made into wine?

(the following I posted on the Home Winemaking board, but it never got answered):

Re: Chardonnay, Riesling,Gewurstraminer, Pinot Blanc, Cabernet Sauvignon, Cabernet Franc, Merlot, Pinot Noir, and others

...have any of you actually eaten/tasted each of these grapes?...How are they?...just curious...

thanks...
