The night before, soak the almonds in two cups of water and leave them there for at least 8 hours.
Drain the soaking water from the almonds.
Place the soaked almonds in a blender and add 2 cups of filtered water and, if desired, your preferred sweetener.
Beat for 1 minute on high power or until you see that the almonds have been completely crushed.
Place the gauze or mesh to strain the liquid over a container or pitcher. Pour the liquid over the mesh and squeeze with your hands to strain the milk.
There should be a fine flour left inside the mesh and the squeezed liquid inside the container.
When you finish draining all the liquid from the mesh, transfer the mixture to a glass container that can be hermetically closed. Keep the almond milk in the fridge for a maximum of 4 days.
