Merlot versus Cabernet Sauvignon?

[quijote]

Thanks, IK--I'll spring for a bottle of cassis. I bought some plums yesterday precisely in order to become familiar with the aroma; they're dark on the outside but golden on the inside. Is this the right kind? I've heard "dark plums" and "black plums" used as a descriptor for varius wines; are they yellow or purple or some other color inside?

Thanks again.
