Place almonds in a bowl and add enough water to cover. Let soak overnight.
Drain and rinse the soaked almonds the following morning when you're ready to make the milk.
Add the almonds, filtered water and sea salt to the and blend until smooth. About 2 minutes.
Place the nut milk bag in a clean bowl and pour the blended mixture into the bag.
Squeeze the heck out of it until all the liquid is extracted. Discard the leftover almond pulp.
Transfer the liquid to an air tight container and store in the fridge.
Notes
Almond milk tastes best when it's fresh but it will store for about 5 days in the fridge. It's normal for almond milk to separate so be sure to shake it before use.
