I love yerba mate, I drink A LOT, and I would like to bring some with me backpacking. Do you think I might save a few ounces to carry if I brewed my mate beforehand, concentrated it into a thick goo and then took that with me backpacking?

How would I do that? Just simmer it for a few days? That seems like not the best idea...

Also, is there any online retailer where I can find such a product for purchase?
