I recently read that a pub trend in Spain is a drink called Kalimotxo (pronounced kal-ee-MO-cho), which is equal parts of red wine and carbonated cola added to a glass filled with ice. Some garnish with a lemon wedge, others don't. It's surprisingly pleasant and quite refreshing. Although it's a new trend in some regions, it's fast becoming an iconic pub offering, especially in the Basque region (though it's served throughout Spain). Some sites called it 'poor man's sangria', and I guess it's fair to say it's somewhat similar, though most sangria recipes have a far more complex fruity taste.
