Wash your almonds properly and then place them in a food container (ideally glass) and cover them with approximately 1 cup of filtered water. Leave them soak overnight. Do not discharge the water they have been soaking in.
Making Almond Milk
Take out your soaked almonds from the fridge. Separate the water and the almonds. Keep the water the almonds soaked in as it's full of flavor and nutrients. Fill up the water to get a total of 4 cups.
Place the almonds, water, dates (without the seed) and salt in the blender. Blend for 1 minute.
Place the nut milk bag in a large bowl. Pour the almond water mixture in the nut milk bag. Now squeeze the bag and get as much liquid out as possible. Keep the left over almond pulp, put it in a freezer bag and freeze it for later use, like cookies or cakes.
Place the funnel on top of your milk bottle. Pour the almond milk from the bowl into the milk bottle and you're done. Enjoy a fresh glass right now or put in the fridge to cool down the milk.
