Unfortunately, 100% Arabica, and not 80/20 Arabica / Robusta as indicated (?)

In the product description is 80% Arabica / 20% Robusta. That's true not appear: On the packaging is 100% Arabica. I write willed "apparently" because I'm not quite sure: The coffee looks like a blend of Arabica and Robusta, and he behaves like this: In my machine portafilter he produced a great crema, the taste is also very good , About for taste known. I think that's a very good espresso. Nevertheless, only 4 stars, on the one hand because of the confusing / wrong (?) Product specification, on the other hand because I know even better coffee beans at a similar price, such as Hausbrandt Nonnino gold, which is also available here on Amazon.
