Add almonds to a bowl and cover with enough water to submerge. Soak 6-8 hours or overnight. This helps them soften enough so that they can blend properly.

In the morning, drain almonds from their soaking water and rinse them in a colander.

Add soaked almonds and 4 cups of fresh filtered water to a high-powered blender. 

Place your nut milk bag over a large bowl or pitcher. Pour the almond milk into the bag and strain the liquid into the bowl, using your hands to wring out all of the milk.

Pour the almond milk from the bowl into glass jars. Almond milk will keep in the fridge for up to a week, if not longer. If it separates, simply shake the jars.
