9. Wine Tasting: Newton
Beyond having exceptional wines, Newton Vineyard, a by-appointment-only winery known for its unfiltered offerings, has impressive manicured gardens and an incredible view of the valley. If you're a serious wine connoisseur, this is a can't-miss spot on your tasting lineup. 

Also noted:
For another memorable by-appointment-only tasting, head over to @ehlersestate, where Hospitality Sales Director Maria Newman will give you a tour of the picturesque vineyards, which are run by the original owners' foundation. (This is one of the few Napa wineries that isn't a large commercial operation.)
