2016 Peay Vineyards Estate Roussanne-Marsanne, Sonoma Coast
The difference in taste between young and aged Roussanne wine is enormous. When young it will taste as described below. With 7-15 years of age, oxidative notes bring to the fore nutty, waxy notes adding complexity while sacrificing zippy freshness. Which is better? Really, it is up to you. The 2016 Estate Roussanne/Marsanne has the structure and character to age so I suggest you buy at least a few bottles for opening many years down the road. Right now, the wine features a baked lemon and gold delicious apple nose with a little unripe mango and some yeast notes. The palate adds a little white peach (very little, not a fruity wine) with floral notes. This is a high acid wine with limestone and saline flavors. It tastes a lot like a Saumur Chenin blanc (high acid, minerally, yet there is some texture). As with many of the 2016s, the 2016 Roussanne/Marsanne is a superb example of what we grow and make.
