Tinto de Verano better then Sangria...
(first descovered during my trip to Tarifa)
Ingredients

Red Table Wine, Diet Sprite or Sprite or fanta, Ice, Lemon Wedges
Preparation:

Place Ice in tall glass. Pour wine over ice until about 1/2 full. Add Diet Sprite or Sprite or the Fanta (diet is a little less sweet) to fill glass. Garnish with wedge of lemon.
This is a quick alternative to the traditional Sangria, but amazingly better!

I've always known this as 'Tinto y Casera' - red wine and lemonade - and have found it a great refreshing drink while cycle-touring.

Sometimes in very small country bars a small new bottle of Casera is used to make the first drink, plus an already opened bottle of wine from behind the bar. The wine is then left with me so I can keep topping-up with the remainder of the Casera! Very good (and very cheap). Bueno!

And for Kalimotxo, just change the soda of choice to coke! yumm :p
