Not only is oat milk very cheap and locally produced but it is also a more eco-conscious choice than say, almond milk. Making your own oat milk is surprisingly easy but storing homemade oat milk and cleaning the bottle afterwards can be a bit tricky so I wanted to shed some light on this in this blog article. For a while, I am making my own homemade oat milk. I usually prepare it at the weekend and store it in a glass bottle for the week.

I buy my oats in a cardboard box which is easy to recycle and easy to store. Only when I need the oat milk will I get my blender out and prepare about a litre for the upcoming week. That is enough for me as I only use it with my granola or every now and then to make a fresh batch of English breakfast muffins. You may need more if you also use it in coffee or for other recipes.

Storing Homemade Oat Milk

The best way to storing homemade oat milk is to store it in some glass container. Maybe you already have something suitable at home. Have a look around to see if you have a bottle that you can repurpose to store your oat milk. I have a glass bottle which I repurposed for this use. I’ve heard other people use Kilner bottles and that works well for them.

Ideally, find some sort of container with a large opening – it will make cleaning so much easier. The one drawback of the glass bottle that I currently use is the small opening which makes cleaning it a bit harder. However, there are effective solutions for this in case you also just have a glass bottle as I do. Read on to find out more!

If you don’t have either you could use any other container that makes it easy to pour the oat milk when you need it. Make sure it fits your fridge well so you can make the most of the storage in your fridge.

However, there is one problem, especially with bottles that I have experienced as well. How do you clean them effectively without any residue? It is pretty difficult to reach all areas of a bottle even with a bottle brush at times. I have that problem with the current bottle that I use so I had to find some easy ways of cleaning it effectively. Luckily there are quite a few options so I am sure one of them will work for you as well.

Cleaning The Bottles

There are different methods but they mostly use the same process. Some water, washing up liquid and some dried rice (or maybe lentils or peas could work as well) and shake the mixture vigorously. Basically the grains will act as a scourer on the inside and bottom of the bottle or jar that you want to clean. Make sure you close the container well. I accidentally didn’t close it properly once and it was a right mess. Don’t add too much water when using this method as the rice should be quite concentrated in one place to be abrasive.

I’ve used this method in the past and it works really well. So happy that I found out about it!

Alternatively, you may want to use baking beans for the same effect. I’ve also heard that people use salt with some water but I have not tried it yet.

Did you try any of these methods? How did it go? Did I forget any good alternative method? If you have a great tip for storing homemade oat milk please comment below and I am happy to add it.
