The last time I went to Barcelona, we decided to spend a few hours out of town. As the weather forecast was not the best, we decided to keep Montserrat itself for another occasion, but headed to its neighborhood.
You can see Montserrat in the background, and a vineyard in the foreground. This is part of Oller del Mas winery. This winery goes back to the 10th century, and has always been the property of the same family. The castle has been destroyed by Napoleon, the vineyard by phylloxera. So the winery was no more. Until the present owner decided to re-create it, slowly, using the best of the ancient practises and present knowledge to produce a bio-ethical wine. At the same time, he rebuild the castle, with modern techniques, but keeping the ancient look. The rooms in this castle host events such as weddings.
High quality equipment has been set up, to make the best of the vineyard.
However, nothing replaces oak.
Such a tour would not be perfect without some tasting...
