What IS it about Red Zinfandel? ? ? Help!

[Marti]

Dear Wine Afficionados,

I am new to wine drinking and fine that I am much more into whites. However, Red Zinfandel is a red wine that I can tolerate and even enjoy. There is something about Red Zinfandels--both smell and taste and aftertaste--that is markedly different than Syrahs, Merlots, Cabs, Pinots, etc. What is it? I cannot put my finger on it! Any adjectives describing the differences between these reds, especially why I might tolerate the red zin. would be greatly appreciated!

Thank you in advance!!!!
