A tale of two worlds is how Spain is described, modern vs. traditional. There are those, who have been producing wine for centuries (just as in Bordeaux and Burgundy) and do so in the same way their ancestors always have. There are also those, who are pushing the envelope by experimenting with more modern techniques of winemaking.
It is a great credit to Spain that even the most modern producers use its indigenous grape varietals and have thereby managed to hold onto Spain’s winemaking identity and heritage. While there are some regions that have taken to planting increasing amounts of international varieties, the focus still remains on indigenous grapes.
