In regard to the green smells, I know Grenache and Syrah, depending on where they're grown, can both throw strong herbal aromas. Perhaps your palette is just more sensitive to these? I mean if you think that's bogus sounding, I just want you to know that all imitation maple smells like celery to me. Whole family dousing their pancakes in celery juice on Saturday morning. (Science explanation: Fenugreek is used to make things smell mapley, but it's part of the celery family) So you know, we're all different, perhaps you're just more sensitive to the green smells.
Either case, hope it comes out good. I have a Grenache/Syrah on my counter waiting to be pitched, so cheers!
