Newbie to Merlot

[Oregonia]

I recently found a Merlot/Cab blend... Before I buy, what should I expect of these blends? Is there a better region to look for? What other blends are worth my consideration? I really like fruity wines... or ones that have a nice flavor.(I know this is vague... sorry). I have also seen some wines from South America and other places that I did not realize made wine... any ideas on these? Should I give 'em a try?
Thanks once again guys!! I'm learning!!
