Add lemon and oranges slices if desired and garnish with mint.
FOR A PARTY:
Add ice to a large pitcher.
Add the bottle of red wine.
Pour in the sprite or sparkling lemonade.
Add orange slices, lemon slices and mint.
Red Wine - In Spain, they make this with inexpensive red table wine. If you can find inexppsensive Spanish red wines, by all means, use them. If you can't though, stick with lighter, fruitier red wines. A Shiraz,Merlot or a Malbec are good choices as are Red wine blends (like what I used). You don't need an expensive wine, but just make sure it's one you would enjoy drinking on its own.
Lemon-Lime Soda - In Spain, they typically use Fanta Limon - but since that can be hard to find in the U.S. I used Sprite. If you like a sweeter, more lemon flavored cocktail, sparkling lemonade (or a mix of lemonade and sparkling water) is a great substitution.
Oranges, lemons, and mint - You don't need these to make the cocktail but they are a nice addition!!!
For a party
Since this cocktail uses soda, you really can't make it ahead - but it's so simple you don't need to! But there are two ways you can serve this cocktail so you aren't making them when you need to be doing other things!
Make a large pitcher and let guests pour their own. If everyone is coming around the same time, this works great!
Set up a drinks station. Set out the "recipe" with bottles of wine and soda. Put the citrus slices and mint in pretty containers. Put out a container full of ice and plenty of glasses and let guess make their own - a great way to "break the ice" at parties!
