Try Central Liquors in Washington D.C. When I would visit D.C. on business I would often stop there and buy some wines from Spain.

I, for one, don't bring back wines that are readily available in the U.S. And I would never, ever bring back bottled Sangria. Sangria is a wine 'punch;' there are many recipes for making it yourself. ¿Why use imported wine to make a punch?

If I visit Galizia, I bring back Albariño or Rosal. If I visit Andalucia, I bring back Manzanilla from Sanlucar de Barrameda. Last September I brought back Orujo de Liébana (Aguardiente). You will find none of these wines (liquors) at the airport Duty Free' shops. And I have not found any of them in the U.S. I can buy Rioja Reserva and cavas from Catalunia at the liquor stores here in N.J.
