Homemade oat milk is, in many aspects, more sustainable than buying both regular cows milk and oat milk in the store. Through making it at home, you don’t need to buy any disposable packaging that’s transported several miles in big trucks. The homemade oat milk is also 5 times cheaper than in the store, with 3 KR per liter! The only thing you need is 3 dl oats and 1 L water.
Making oat milk at home easily gets messy due to pouring the milk back and forth in different containers, and the amount of dishes for such a simple process is insane. Through straining directly in a funnel with a connectable sieve, you minimize both the number of steps in the process, and the number of dishes used.
