Castello di Amorosa or Castle of Love is a definite must-do in Napa Valley. We planned only 1 hour there but I tell ya', we time warped to medieval Tuscany and stumbled out in a (sober) stupor 4.5 hours later. What a dreamy place! It may be California wine country but depending on which winery you're in, you could very well be in a chateau in France or a vineyard in Italy. I actually purchased my first wine (don't like liquor remember? so much for that.) – Fantasia, a delicious & sweet partially fermented rosé that I happily packaged in a new vintage-style leather wine case from the winery boutique.
