Do you have any pictures of the sap?
An Americano is a double shot of espresso with 2 oz. of hot water poured over the top. It is a strong cup of coffee with a milder profile than an espresso. I have a Long Black every morning which is 2 oz. of hot water with a double shot espresso pulled over the top, same ingredients with a vastly different flavor profile. The oils and head remain on top more like an espresso shot, not quite as strong as the straight shot but twice the volume so it lasts longer. I cannot drink two double espressos in the morning it is just too much caffeine and a single double shot is just not enough!
