Winemaker Adam Comartin has a rich family history in the butcher business. Growing up, Adam's grandfathers, William Sr. and William Jr., proclaimed the Porterhouse cut as the finest.




"With this in mind, the Porterhouse Winery was born with an absolute dedication to producing only the finest wines."

William's Reserve

2014, Santa Ynez Valley

Williams’ Reserve is a tribute to Adam’s grandfathers—a selection of the highest quality barrels in the winery blended in perfect harmony and balance.

Santa Ynez Valley runs East-West with no mountain range blocking the valley from the Pacific Ocean, which enables the cool air and fog to penetrate the vineyard during the long summer days common to Santa Barbara. This is important because it allows for more even ripening and produces balanced flavors.
