01 - Place the raw almonds in a bowl and cover with water. Soak for at least 8 hours or overnight. Drain and rinse thoroughly before using.
02 - Add the soaked almonds and 4 cups of fresh filtered water to a blender. Blend on high speed for 1 to 2 minutes until the mixture is smooth and creamy.
03 - If desired, add sweetener, vanilla extract, and a pinch of sea salt to the blender. Blend briefly to incorporate the flavorings evenly.
04 - Place a nut milk bag or a fine mesh strainer lined with cheesecloth over a large bowl or jug. Pour the blended mixture through to separate the liquid from the almond pulp.
05 - Squeeze or press the nut milk bag or cheesecloth thoroughly to extract as much milk as possible from the pulp.
06 - Transfer the almond milk to a clean bottle or jar with a tight-fitting lid. Refrigerate for up to 5 days. Shake well before each use as natural separation may occur.
