Decide the area you want to explore - There are so many places so it is best to narrow down different areas to explore and focus on one area for each day that you are there.
Tips on How to Pick the Area - First Decide if you want to go to the East Side or West Side of Paso Robles or the new Tin City. Do you prefer smaller boutique vineyards or do you want to visit your favorite winery that you can find at your local market? The dominant grape grown in Paso Robles is Cabernet Sauvignon. If this is your wine of choice then you should spend an afternoon at Daou mountain and a second day on the east side of Paso Robles. If you like Rhone varietals then the above guide is perfect for you! You can also explore other wineries located on the West side of Paso Robles.
Determine where to stay based on what you would like to do besides wine tasting. If you want to enjoy the downtown then check out the Lofts at the Paso Market Walk to discover a great new mixed use development space close to downtown Paso Robles. This is also super convenient as you can grab a coffee as well as food to go to help get you through the day of wine tasting.
This is how I would plan my tastings for the aforementioned wineries due to location:
Day 1: Denner, Tablas, Adelaida, Daou (This allows you to work your way back to town and Daou is a great place to be during magic hour).
Day 2: Caliza, Booker, L’Aventure (All three of these wineries are neighbors, however, L’Aventure is off a different back road. Also would have loved to taste Booker, My Favorite Neighbor and L’Aventure back to back as My Favorite Neighbor is Booker’s tribute to L’Aventure).
