Non-whey non-soy protein drink?

[OakLeaf]

I wonder if anyone makes a non-cow whey drink....

I'm actually a LOT more allergic to goat's milk than I am to cow's. Sheep's milk, I'm not sure; outside of pecorino romano I've never had it.

I'm not lactose intolerant at all. For all the problems I have with dairy, digestion isn't one of them. The difference between cheese and whole milk for me, I just realized when I posted above, is that I'm more allergic to the proteins in the whey fraction than I am to the casein and/or whatever else stays in the curds.

I do on occasion use hemp, rice, pea and potato protein supplements, especially as a recovery snack. But all of those products that I've used are more like a shake or a smoothie. Not something I'd really want to put in my hydration pack and consume on the run. I'm looking for something more soluble.
