Anybody who has ever had Sangria before knows it is the cheapest way to get drunk without tasting the alcohol. This is how you make it from scratch:
1 jug of cheap wine. I use Carlo Rossi because you can get a ton of it for less than $10.
Liquor (amount of your choosing) – I used bourbon last time, but you can use vodka as well. Be careful not to add TOO much of this if you include it though
Lots of fruit. I used peaches, pineapples, berries, etc.
To make it, just throw everything together in a large container and let it sit overnight. The fruit will soak up the alcohol, and it will just taste like a sweet, fruity drink.
