Just split all the small towns and seems like some trends that aren’t surprising. Catalonia is the big beer region as far as I can tell. A bunch of cideries in small basque towns, Valencia, Andalusia, Madrid and Castile-Leon have a decent brewery showing, and Galicia only kind of.
Outside of that it seems like pickings were few and far between. Only a couple of places in La Rioja, for example. Castila La Mancha, Navarre, Murcia and obviously the moroccan territories are pretty empty for places at least. Not sure if these stats reflect beer availability as this is just what I could tell from updating places in small towns.
