First, place dates, water, and salt into a high-speed blender and blend until dates are completely pulverized and blended into the water.
Next, place rolled oats into the blender and blend for about 1 minute on high until oats are broken up, but not pulverized. If you pulverize the oats too much you will end up with a filmy and slimy consistency (believe me, this has happened to us!).
Next, place a tea towel or nut milk bag (or any other very thin towel) over the top of a tall mason jar or pitcher.
Slowly pour oat milk mixture into the tea towel to strain out oat fragments. You may have to squeeze the towel a bit to push the oat milk through the towel. Repeat until all oat milk has strained through the towel (be patient, sometimes this takes a while).
Place a cover on the mason jar and store oat milk in the refrigerator for up to 7 days.
