Oh man, there it is again!
If you wanna find thee elusive umami, here's where it lies. Get deep in your cups. Pull out a Siboney and light er' up. You will notice that the initial dry cocoa. Wait for it. Wait for the last 1/3 and you will find this umami. It's a savoriness that is not commonly predominant. This umami, if you will, comes on like a silky beef broth. It's oh-so-umami.
