We spent two days in Napa Valley. We are staying at "The Old World Inn" B&B which really very nice and comfortable. The breakfasts were fabulous and each evening there was wine tasting.
We spent our days driving to some great vineyards and tasted LOTS of wine. Napa Valley is only 26 miles long in the valley and basically most of the vineyards are along one main road. Napa Valley produces less than 2% of the California wines. Most of the vineyards are quite small and all the harvest is done manually.
We stopped at Castello Di Amorosa, V Sattui, Grgich Hills, Robert Mondavi, and Artesa Vineyards.
We loved our time in Napa Valley!
