I discovered this quick hack after my almond milk suddenly began to spoil within 48 hours of making it. Normally, my homemade almond milk would lasts 4-5 days in the refrigerator, so it was a bummer when it started lasting half as long and had to be poured down the drain. Homemade almond milk and other nut milks are very perishable and must be kept refrigerated at all times. Don’t know how to make almond milk? Here is a recipe!
When my almond milk began to spoil quickly, I assumed the culprit was the nut milk bag. I had this nut milk bag for a while and I figured that there must be some bacteria hiding in the lining. So, I purchased a new milk bag, thinking that my problems were solved.
YET, even after using the new nut milk bag, my almond milk continued to spoil within 48 hours. 🙁
Then it dawned on me. I had been noticing that fruit flies really liked the bowl of soaking almonds. I didn’t think much of it previously because I rinse the almonds really well after they had been soaking. But then a light went off! Fruit flies insert mold into food, encouraging it to spoil faster. Well, the fruit flies may have been inserting mold into the water, encouraging the water to ferment….and even though I didn’t leave the nuts soaking for longer than 12 hours, the mold could have gotten into the almonds, encouraging my almond milk to spoil at a faster rate. (SCIENCE!)
So, once I theorized that this may be the problem…I simply covered my soaking almonds with a lid. And guess what!? My almond milk now lasts for 4-5 days again. Yippee!
