I found Pony Malta in the back of a liquor store in Guayaquil, Ecuador. It comes in a little bottle for only 15 cents. It claims to be a natural and refreshing energy drink, but I still didn't feel any increase in energy after 5 minutes, and still not much after drinking the entire bottle.

It's a malt beverage like kvass, so it tastes similar but a bit better and is also slightly carbonated. The flavor also reminds me of tamarind. For a more familiar flavor, it also tastes a bit like prune juice. It's dark and not very fruity though.

Overall as an energy drink I wouldn't rate it very high. I'm not sure about the caffeine content of Pony Malta, but if you're just looking for something to wake you up I would say go with coffee. This particular brand of Malta comes from Colombia.
