The berries are distinguished by their russet color when ripe—"roux" is French for the reddish-brown color "russet", and is probably the root for the variety's name. The aroma of Roussanne is often reminiscent of a flowery herbal tea. In warm climates, it produces wines of richness, with flavors of honey and pear, and full body. In cooler climates it is more floral and more delicate, with higher acidity. In many regions, it is a difficult variety to grow, with vulnerability to mildew, poor resistance to drought and wind, late and/or uneven ripening, and irregular yields.
