It’s hard to find and try new wines without just happening on the location along the road. Thus far we have to yet really get off of the highway much and explore new winery locations. In Paso Robles, if your not on the main roads you may as well forget it unless you have someone out promoting you someplace. All wine and winery’s that I’ve tried away from major thoroughfares we’re suggestions given by other enthusiast.
Pear Valley is almost the only winery that I have tried that was really off of 41, though it really wasn’t that far down Union from Tobin James, another winery that I had yet to try at the time. Pear Valley was recommended to me by a friend who really enjoys their desert wine, Orange Muscat, which I continue to return for and enjoy on very rare occasion.
There are many winery’s down Union just east of Paso Robles I would encourage you, along with myself, to head down Union sometime, there are even touring maps for Union that you can pick up at many of the local winery’s.
