Marsanne is an interesting grape, native to the Rhone Valley of France. In fact, the grape is barely grown outside of the Rhone (plantings are steadily increasing in CCalifornia though) where it is often blended with Roussane.

One of the standard complaints with the grape from vintners is that it is more vintage dependent than other white wine grapes which could be grown in similar sites, in California that can mean Chardonnay or Sauvignon Blanc in cooler climates, or Roussane and Viognier in warmer conditions.

At Uncorked Ventures, we appreciate it's bigger body when fermented in oak barrels which isn't always the case.
