California's Paso Robles has seen explosive growth in its number of wineries over the past decade. The region now has nearly 200 licensed, bonded winemakers. If you have a weekend or so to visit, there's no way you're hitting them all (and living to tell about it).
So here's my pick for a few places worth seeking out:
Anglim Winery — Husband and wife (Northwestern graduate and former Chicagoan) team run this high quality, boutique winery where you can enjoy a free tasting (or pay a few bucks to taste their reserve wines).
Adelaida Cellars — The region's first pinot noir was planted here at this lovely winery and vineyard that has a cozy tasting room and friendly staff.
Halter Ranch Vineyard — My favorite of the bunch. Gorgeous setting by a restored Victorian home, where they'll sometimes have wine dinners and other food-related events. Ask to see the ginormous oak tree on the property.
L'Aventure — A colorful Frenchman is in charge here, and the result is spectacular. This place is known for taking chances and blending some unusual varietals to come up with truly unique wines.
Robert Hall Winery — One of the prettiest vineyards and wineries I've seen in California. They sometimes have concerts on the sprawling grounds.
Justin Vineyards & Winery — This is the place that put Paso on the map. It's a little far removed from the other wineries, but fans of Justin wine will want to make the trip.
