I’ve read 3 days or so, but living alone, I would never go thru it that fast, yet really need it when I need it. I make somewhat small amounts at a time. I’ve tried it 5 or 6 days after I’ve made it and seems to be ok. How long does yours last, and if its no longer good, does the taste change, or how would I know?
Someone mentioned in another thread that they make sunflower seed or hemp milk using only 1.5 TB of seeds (sunflower seeds soaked overnight) and 3/4 cup or 1 cup of water. This might be an idea for you. You blend until smooth, then use. No straining is necessary. I’m sure you could could make use of that little amount within a day. I imagine almond milk would be good for at least 3 days, but I wouldn’t take chances with trying to keep it much longer. Just keep your batches really small.
