Although Teruel is not a major wine producing region this should not put you off visiting. It is a beautiful area and according to the article below from ‘the local’ it’s capital city has the highest number of wine bars per person 53 per 100k people.
Mind you this mainly because the Teruel region is one of the least populated areas of Spain. Still at least you don’t have to fight to get a space in the bar as often happens in the more popular bars of Madrid.
There’s a lot to recommend this place.
