Now that I have your attention, I am to old to lactate. I am making plant based milks. So far I have tried almond, cashew, soy and oat. Oat milk is by far my favorite and here's why:
No cooking like soy milk
Hardly any waste product like soy and almond. It was a pain to find something to do with that okara and nut fiber leftover from soy and almond milk.
Organic oats are cheaper than organic almonds and organic cashews.
It's slimy - I like that and rolled oats soak fast so you can have milk in a couple of hours.
I buy organic oats in bulk so no waste.
