I can't find many resources to explain how changes in profiles create different tastes (I wish I could get my hands on that Bella Barista users guide). Similarly, I understand dialing in a grind on a pump/lever espresso machine, but I'm confused where grind plays a role in a flow profiling machine. I know you can grind finer, but do you then to make small adjustments by taste do you just adjust the flow profile or alter grind? The basic adjustments by taste seem to be lost in all of the profiling variables.
Can anyone answer those questions for me or share some resources that may help figure that out?
You can find a lot of the answers to this on the Bianca thread: Lelit Bianca User Experience
Short answer, dialing in with the Bianca is way easier than with a non-profiling machine since you can adjust the shot on the fly. It takes me just one or two shots to dial in almost any coffee and the shots are drinkable. It will take you a few weeks to learn to profile, but after that you would not want to do without it, keep in mind that it can be used as a regular E61 too. I posted a video of a 72 second shot I made about a month ago, this should give you an idea of the flexibility:
