Not one of my favorites, but interesting and fun for visitors. There's a fee to ride the tram up, but I think it applies to purchases and/or tastings.

Another (newer) architectural extravaganza is Castello Di Amorosa (sp?), set on a hillside overlooking Sterling; part of the V. Sattui group founded by Dario (ex. Daryl) Sattui, another Cal Old Blue.

Also at that end of the valley and on my list of faves: Chateau Montalena, Frank Family (in the old Larkmead Lane/Hans Kornell facility), and Rombauer. The former two are in/have old buildings, the latter is more modern. All have great wines.

I'll circle back later and insert some photos.
