It's not very clear but it looks like there are the beehive shaped buildings in the background common in La Rioja. That's my guess, but I could be wrong.
You can see a clearer picture of one here:

I will pretend I didn't see this and preserve the magic of the film!
Hi there, this is Rodrigo here, back on the block. Those vineyard scenes, and by the way, no serious caminante walks through vineyards, were filmed right in front of the lovely village of Briñas on on a very sharp bend of the Ebro river just a few kilometers away from Haro, the provincial capital of Rioja Alta which boasts of being "la capital del Rioja", that is the capital of Rioja wine. That specific location is lovely, but a a dead end. There is no bridge that allows you to continue in direction of Labastida or San Vicente de la Sonsierra and that would be heading north which is the wrong direction if you were trying to get to Burgos. But those scenes where they're walking on a dirt trail along the river, which you can't see in the movie but I know because I live here, is the trail heading into Briñas coming from Haro, and, again, they are walking in the wrong direction. A peregrino would theoretically walk this trail coming from Vitoria-Gasteiz, and I did once meet a Spanish peregrino walking there past Briñas. I asked him where he had started his hike, and he indeed said from Vitoria-Gasteiz, however, it's a very rare trail for pilgrims, and you would be walking in direction of Haro, then Casalarreina, Castañares, and then on to Santo Domingo de la Calzada where you would join the Camino Francés and continue on to Castile, province of Burgos. However, you coud opt to bypass this whole stretch and go by way of Miranda de Ebro which is a city already in the province of Burgos. BTW, the kings of Spain were in Santo Domingo de la Calzada and Haro last weekend; but not that I care
That being said, the original Camino Francés bypassed la Rioja and used to go through Vitoria-Gasteiz in the early Medieval Ages. And yes, those conical stone buildings are common here in la Rioja and are called "Guardaviñas" and used to be used as a shelter for workers working in the vineyards.
