This is a full day trip. Be sure to dress appropriately, the wineries are outside of SF and the temperature rises quickly. The first two wineries were a blast to visit (Roche & Madonna). Good wines, good pours, beautiful scenery and the employees were fantastic. We stopped in Sonoma for lunch and we ate at La Casa (Mexican) - great choice and recommend. The last winery, B.R. Cohn was somewhat disappointing and we felt rushed. Only one staffer on hand for our group. The pours were quick & small, and took longer (no second pours). Scenery at B.R. was fabulous, but we were on and off the bus quickly and interaction with the staff was minimal. Almost like our tour group was impeding on their day. We made a quick stop under the Golden Gate Bridge on the way back to SF and we’re treated to a drive through and history of Presidio. Our tour guide Thomas was fantastic - he made the trip. Would have given the tour a higher rating, but B.R. Cohn was a let down.
