Wine Tasting is the main reason most visitors come to Paso.  There are over 200 wineries in the appelation.  Here is a quick reference of the best, the most, the favorites...

Tobin James Cellars.  The winery with the self-proclaimed most popular wine club in the world, the "James Gang."   Western themed tasting room and reknowned parties.

Eberle Winery.  The most extensive caves, with an informative cavern tour.  One of the founders of the Paso appelation.

Justin Winery.  The highest rated winery among TA reviewers at the time of this writing (and very highly rated by critics).

Rotta Winery.  Once the oldest continually family-owned winery in the region, and home of the unique black Monukka, Rotta has now been sold to an outside investor group. The company has hired Jeff Branco, former winemaker at Justin Vineyards, to develop Bordeaux-style wines. The winery currently produces about 5,000 cases of wine each year, but Shorrock said it has the capacity to produce 20,000.
