8. Wine Tasting: Domaine Carneros
When it comes to wine tasting in Napa, you should keep in mind that not all tasting rooms are accessible without an appointment. If you're looking to just pop in, head over to @domainecarneros. The property is modeled after a French chateau, has ample outdoor seating on its terrace and is know for its sparkling wines—which you can order a flight of for your sipping pleasure. 

Also noted: 
@Tankwinery's new tasting room in Calistoga (no appointment needed) is housed in a former filling station and has a cool, hipster-esque vibe that's far from ubiquitous in Napa Valley.
