We were very blessed to have had a awesome guide for this trip and he set up some of the most wonderful tastings. We were able to stay at the Madrona Manor in Healdsburg and would do it again. (Michelin Star Restaurant on Site)
My advice would be to make reservations at the vineyards you want to visit because they can get super crowded during the peak times. I strongly recommend taking advantage of the more premium and private tastings to have a better experience – its worth it as the wineries enjoy letting you taste many of their higher end wines. All the wineries we visited were exceptional, unique, and the wines very easy to drink. What we learned; enjoy the wine experience and it is not a rush to see how many wines you can taste, it is about experiencing the joy of wine.
