Background

In industrial oat milk production, commercial amylase is often used to break down starches for a smoother texture. This experiment is an attempt to use the enzymes naturally present in Light Munich malt from Valley Malt to achieve a similar result. The goal is to break down the starches from the oats (from Wild Hive Farm), creating a smoother milk without a starchy mouthfeel, while simultaneously developing malty flavors.


Recipe

Ingredients

90g Dried Oats

45g Light Munich Malt

~700g Water

Equipment

Pot

Blender

Thermometer

Cheesecloth or Nut Milk Bag

Instructions

  1. Boil Oats
    Boil the dried oats in water until they are just soft.

  2. Combine and Blend
    Add the malt to the pot and blend the mixture thoroughly.

  3. Saccharify
    Hold the mixture at a constant temperature of 140-150°F. This allows the enzymes from the malt to break down the starches from the oats. After holding this for around 30 minutes, move the temperature up to 160-165°F for an additional 10 minutes.

  4. Strain
    Strain the liquid through a cheesecloth or nut milk bag.

Notes and Observations

  • The final product has a nice mouthfeel, similar to a store-bought barista milk; it is relatively thick and concentrated.
  • It has a strong oat flavor with a malty aftertaste. It would be delicious on its own or used as a base for drinks.
  • It would be worth doing further testing using it as an ingredient in baked goods.
  • It would be interesting to try this malting technique with other starchy ingredients like other grains or peanuts.
