It sounds like you know your stuff, so I'm confused. What you're describing (old, cold coffee) is nothing at all like what I'm enjoying.

What comes out of my Osma is fresh, ice chilled (by uh, ice), rich and all of the flavor notes are present. There's a nice foam on top that is technically not crema, but cavitation bubbles. It's strong like a well-poured Espresso shot, but with none of the burnt acidity.

I promise you that if you cupped what comes out of my machine alongside a literal glass of old, cold coffee... one tastes like victory and the other would make you gag.
