I'm currently in Spain and will be travelling quite a bit of the country. any wine suggestions out there? I'm sitting on a balcony at Marques de Riscal. Visited Rioda and Tondonia this morning after landing (along with Marques de Riscal). Will be here for another day before heading back to Madrid for a couple days, then to Alicante/Murcia area for a week and finishing in Barcelona for four days. Any suggestions are appreciated.

I enjoyed walking around LaGuardia and visiting a few of their wineries, and I believe it's in the same area. We went in 2018 so I could be mistaken.
The town was originally built as a fortress and is completely walled in with tunnels built for protection now being used for wine.

Casa Primica was built over the ruins of the old city and you could see the excavation below their floor. Neat tour.

El Fabulista wasn't as good of wine, but their tour brought you down into the tunnels of the city.

One of my favorite areas is the Galicia region eating sumptuous seafood with the areas Albariño.
If you are in Barcelona go to the Priorate area. From my understanding it was not a strong producing area but expatriate English made it quite desirable.

Only been once, to Valencia, but try to get some paella there if you can.

We made it over to Laguardia today and lucked into a visit and personal tour from the owner of Artadi. They had a group from Japan training for master of wine accreditation and we got invited to tag along. Some great wines and very insightful about the winemaking process.

If you are still near Madrid and can rent a car, head out of town about an hour away and visit Bernabeleva. You have to make a reservation but it is a small operation. The owner will take you all through his vineyards, which is fascinating how they grow their grapes as opposed to over here. There's lot of wine to be tasted and he was pouring straight from the barrels and tanks for us. Really great wine and very reasonably priced too. I believe we brought home 6 bottles.

If you are able to make it out that way, consider also stopping at Bodega ValleYglesias. You'll meet in town (San Martn de Valdeiglesias) at their restaurant and then they'll take you out to the winery which has an amazing view of the mountains. They have great red wines and are also reasonably priced.
