This was my first Napa Valley tasting and I was shocked at the cost of a wine tasting. They charged $20 per person plus tax to taste 4 wines. They filled the glass with less than an ounce of wine. They did let my husband and I "share" a tasting so it only cost $20 + but we had to use the same glass and "share" the wine. It was hard to get two sips each.
We did get to see the famous bottle of Chardoney from the movie "bottle shock" but there was little else to see. We purchased a bottle of Riesling and the total bill with tasting was $47. It was not worth the money. Save it for somewhere else.
