You won't believe how simple this was to make! Take a french press/ jar/ whatever and fill the bottom with a bit of coffee. Fill with cold water and let it chill in the fridge for 6-12hrs (depending on how strong you like your coffee), then strain and serve!
I added some ice and my favorite creamer. It's delicious and doesn't have nearly the acidity of hot coffee! It's a much more smooth taste. Enjoy!
