Homemade oat milk works great in baked goods, smoothies or cold beverages. But it’s not the best option for hot beverages as it may thicken up and become slightly slimy. It also do not froth well as it lacks fat unlike nut milks.

Normally homemade oat milk is slimy and here is a few tips on how to make it less slimy:

Use ice cold water: heat makes the oats more starchy and gummy so use ice cold water.

Don’t over blend: if you blend the ingredients too long they’ll start to warm and you’ll run into the same problem above. Don’t blend for more than 30 seconds.

Strain well: strain through a high-quality nut milk bag with a very tight weave.

Don’t over squeeze: as you’re straining and squeezing the oat milk in the nut milk bag, be gentle. You don’t want to squeeze firmly like you do with almond milk as you’ll squeeze out more of the starchy compounds.

How do I store the oat milk?

After it’s blended and strained, pour the oat milk into an airtight jar. Then store it in the fridge for up to a week. Note: without any stabilizers or emulsifiers the milk will separate in the fridge. This is normal. Just give it a good stir before drinking.
