This is a compelling and delicious blend of 54% Grenache Blanc, 21% Viognier, 14% Marsanne, 8% Roussanne and 3% Vermentino from Doug Margerum's new estate property. Crisp Asian pear, apple blossom and stargazer lily aromas lead into a very grippy, tense and chalky palate full of nectarine sorbet, lime rind and tangerine flesh flavors.

The just-bottled, 2017 White M5, Margerum's white Rhone blend, is bright, nuanced and wonderfully focused, with the energy of Grenache driving the wine's personality. Citrus, orchard fruit and floral notes are nicely delineated in this attractive, inviting white.

Crisp and vibrant, with green apple, ruby grapefruit and lemon curd notes that leap out of the glass. Harmonious and intense on the long finish, where an appealing hint of almond skin comes in. Grenache Blanc, Roussanne, Viognier, Marsanne and Vermentino. Drink now. 1,400 cases made.
