Would the use of a non-Versalab M3 (Rocky, Mazzer etc) produce a shot of the same quality? I am wondering how much influence you think the Versalab is having on your shot quality on the Brewtus.
The color & texture of the extraction, as seen in those pictures can be achieved with the Mazzer Mini on the Brewtus. Beyond the grinder's contribution, It is mostly determined by the Barista skill and beans used. The machine of course plays a role here too. If the temperature is not right, pressure wrong, and generally the machine is inconsistent in execution, it will negatively affect the visual and more importantly - the cup.
As to flavor, the M3's flavor profile is different from the Mazzer - and it is hard to generalize in which way it is different, because it changes with every blend you use. Generally speaking, it is more rounded, especially on acidic high growth coffees. But I also noticed more complexity in the cup. That attribute is independent of the machine used. I don't want to give away too much about the M3 in this thread as I plan a post specifically addressing flavor on the M3 Bench.
