busted: zagu's double espresso

Zagu's Double Espresso doesn't taste like espresso at all. I expected it to be darker and more bitter than its cappucino version. It is more bitter than the latter in a considerable degree, yes. I know I should have not expected that much from such a cheap drink but still cheap things sometimes offer better quality than expensive once. For instance, I prefer Zagu's Natural Mango more than the mango shakes I have tasted in pizza restaurants.
