One of the other Grand Cru sites on Vineyard drive, Sorso has been a backbone of MFN since 2015. Owner John Zimmerman never speaks of the business side of growing grapes; he is singularly focused on cultivating the kind of fruit that makes world class wine. No matter what. The vineyard is run by soil scientist Steve Viera whom is wildly respected throughout the state of California, and together their passion is highlighted in every bottle of MFN. Another cooler Willow Creek site, we usually don’t harvest here until the second week of November!
