You might want to taste a wine from each of the Spanish wine regions. We have recently done so for Italy. The experience was so positive we expect to repeat it for Spain.
This is our Spanish wine list, containing red, white, sweet, and sparkling wines. We don't have any cheap wine, but we do have inexpensive wine. In a few clicks you can get essential information about a given wine, where it comes from, what kinds of grapes are in it, characteristic flavors, and a few food suggestions.
