2018 Rossi Ranch GSM
2018 Rossi Ranch GSM
Heritage, Organic Sonoma Valley Vineyard - farmed by legendary viticulturist Phil Cotturi

After making my misc. stuff GSM, I decided I wanted to finally make a vineyard-designate blend. The Rossi Ranch GSM showcases the amazing terroir of this heritage vineyard and allowed me to work with each of these varietals separately and then together to create the perfect blend for aging.

Black cherry in color with aromatics of wild raspberry, strawberries, cola/Dr. Pepper, and black licorice with savory notes and smoked game notes. Loaded with black and red raspberries, plus sweet strawberries, and red and black licorice. A pure pinpoint intense savory aspect that flows through out the wine, with just a touch of white and green peppercorn notes. The palate is very giving, from the lush front palate to the luxurious midpalate to an everlasting finish. My passion for wines of the southern Rhône continually drives me to find the best vineyards from which to create an epic GSM; one not of sheer power, but one of intensity and elegance.

Blend: 100% Organic - 60% Grenache, 20% Syrah, 20% Mourvèdre

Why This Wine?

My passion runs deep for wines of the Southern Rhone, especially Châteauneuf-du-Pape, Vacqueyras, and Gigondas. So, my continual journey and experimentation of Grenache, Syrah, and Mourvèdre is not only fascinating, but gives me chance to understand how to not only find the right vineyards, but picking profiles, fermentation techniques, and aging vessels to use. Then to compare my wine with those of my favorite producers in the Southern Rhône.

92 Jeb Dunnuck - Solid black cherry and mulled blackberry fruits as well as pepper, orange peel, and leafy herb notes emerge from the 2018 GSM Rossi Ranch Vineyard, a medium-bodied, nicely textured, seamless blend of Grenache, Syrah, and Mourvèdre. It shows a solid kick of tannins on the finish but is far from unapproachable, with beautiful balance and length. It should drink well for at least 7-8 years. 94+ Wine Advocate - The 2018 Zinfandel Rossi Ranch comes from more than 100-year-old vines farmed organically by Phil Coturri. It was made with 20% whole cluster and aged 18 months in 20% new French oak. Medium ruby, the nose has broody, dark fruits laced with graphite, iron, charcuterie and pipe tobacco accents. The palate is densely fruited but fresh, with a fine grain and mineral notes on the finish. Give it another couple of years in bottle.
