LMSC The taste notes have been something beyond my early machines’ capabilities so it really (almost) became “obsession” (this is a joke, Captain Obvious) once I crossed a threshold.
Sometimes with the right beans I have been able to drink literally sweet shots with lots of caramel, chocolaty flavours. Recently I had some mid-roasted beans, that were very citrussy in flavour. I had someone to check on our insulation and the guy had a couple of double ristrettos in the framework of 30 minutes. He kept on saying how citrussy the shots were. My wife found the coffee acidic. Go figure 😆.
I believe that if the notes were something you sense and enjoy it is definitely worthy looking for it. If, however, this is the primary goal, I will definitely not join. As long as you enjoy your shots, notes or not, this is what matters (at least to me).
PS BTW my wife and I are currently in Sardinia (Sardegna) and I have to admit that the person in MIlan who told me not to hope for great coffee here was right. I only had 2 or 3 out of more than 10 good shots. Fortunately Sardinia is not all about coffee and we are having great time.
