For more than 20 years, on my way to visit family members in Petaluma and points west, I’ve seen the Keller Estate sign on Lakeville Highway. And for years my impression of the winery, based on nothing more than the look of the sign and its location in the flatlands north of the San Pablo Bay, was, well, less than impressive. I imagined that, should I follow the sign, I would find a simple, run-down, peaked-back-in-the-’70s establishment, more than deserving of its out-of-the-way spot on the border of lower Sonoma County.
