Grenache, Syrah, and Mourvèdre are the three grape varieties used in GSM blends, which are commonly blended together in the Rhone Valley in the South of France. Grenache adds acidity and bright fruit aromas. Syrah imparts aromas of violets and carnations, and gives wine structure. Mourvèdre adds dark fruit flavors such as blackberry, as well as a gamy, earthy quality.
The Grenache and Syrah are grown in the Edna Valley, in San Luis Obispo County, within 10 miles of the Pacific Ocean. The region experiences cool days and nights. Rocky, shale soils allow the grapes to fully mature from ample hang time. The Mourvèdre is grown in the town of Oakley, in Contra Costa County, and was planted in extremely sandy soils by Portuguese immigrants more than 100 years ago.
In early 2015, California experienced 30% more rainfall than in prior years, easing concerns over a possible fourth consecutive drought. Bud break in March was normal, but May was cold and wet, disrupting bloom and reducing crop loads up to 40% in some areas. Despite this, the vintage produced wines that are more structured, ensuring greater ageability.
