I wonder if those barrels are decorative or actually filled with wine?
There's another that's a old van emblazoned with the winery's name. I've seen it at the winery and on the road around town a time or two. The tasting event I went to was held in the building on the right in the photo below. Across the street, on the left, are the caves where that big group of cyclists was taken. If you look very closely, you might see the row of tables on the sidewalk outside the cave, just behind the aqua-colored Renault. Down the middle of each table is a line of empty wine glasses. I don't know if the glasses were for the cyclists or if that was the set-up for the day's lunch event. I didn't stick around to find out.
The ends of old wine casks adorn the wall outside the winery caves.
