There are three major variants of this wine as per George Nader. The subtle flavor, taste and color all differentiate between Spain, France and US. The Spanish Grenache has a very fruity and sweet flavor that can be accredited to the warmer climates and temperature. French on the other hand will lend a certain smoky herbal note. It will remind you of oregano, tobacco and often lavender. The finesse is less in French variants although the characteristic cherry flavor is well present.
US Grenache is like everything else American. It is bold, cult and definitely crisp in the presence of right flavors and acidity. The American version stays true to its Old World roots with hints of flowers and licorice. The American Grenache is known to be blended well with Syrah in order to add tannin and procure a very smooth flavor.
