In this episode, we are back at Warnecke Vineyard and on the trail of any pesky vermin who may have an eye out for grapes. Winemaker Joe Hurliman and Vineyard Watch Dog Zephyr take a stroll past Cabernet Sauvignon on this second trip up north to Sonoma Valley. Gophers beware – this Parson Russell Terrier takes his work very seriously.
