In a small pot, combine ¼ cup (60 ml) of the filtered water with the Redpath® Organic Granulated Sugar. Place over medium heat and bring to a boil; stir to dissolve sugar. Remove from heat and allow to cool completely.
In a blender, add in the remaining filtered water (1000 ml) with the large flaked oats, vanilla extract, salt, and the cooled simple syrup.
Process by pulsing the mixture until relatively smooth. Pulsing the oat mixture versus blending continuously helps to ensure that the oat beverage does not get over blended.
Place a fine-mesh sieve lined with a layer of cheesecloth over a large measuring cup or bowl and pour the oat beverage into the strainer. Repeat this process twice for a smoother drink, rinsing the mesh between strainings.
Store the oat beverage in an airtight glass container, pitcher, or jar in the refrigerator. Shake well before use as the beverage will tend to separate when left standing. Will keep in the fridge for up to 5 days.
