Marsanne is a little used variety of grape, most common in the northern Rhône, where it is often blended with Roussanne.

The wines created from Marsanne are rich and nutty, with hints of spice and pear. Often Australian Marsanne has aromas of melon and honeysuckle.

In California, Marsanne is often found blended with Roussanne, Viognier, and Grenache Blanc. In wines based on the richer Roussanne or the more floral Viognier, Marsanne is prized for its reflection of minerality.
