I find wine interesting as there's often some kind of history behind it. And, great wines are usually not quickly made. Recent documentary on Netflix called Somm:Into the Bottle went into pretty good detail around it. A Year in Burgundy was also interesting, if you're into French wine. Like most food documentaries, often the stories surrounding them are the most interesting.
I can't recall any wineries that stood out at the festival, personally. I do remember thinking Chalone Pinot Noir was pretty good Pinot Noir.
The foods were pretty good. I went a little more specific on my Yelp review.
Here is my Yelp review.
Lots of wineries from OC
Various foods and vendors
Hangar section gave you a bit more shade while tasting
Got crowded around 2pm
