This is all on my setup of: Versalab grinder + S26 commercial HX from Rancilio + SO home roasted. I stick to a normale, rather than ristretto, brew ratio because I find it more balanced for most coffees; my infrequent magical espressi are, also almost always, normales. I change grind, dose and basket when I'm dialing in a new coffee, but I tend to generally favor a 14g dose in a Rancilio double or a 16g dose in a Synesso double. Channeling almost never happens, after years of doing this I think I got it right, and I exclusively use a naked PF.
But the question remains: with so many proud H-B here, how many do get that smell/taste magic often enough? Why/how are you getting it? What were the technique or gear changes that made it happen to you?
Very very infrequently, I'd get a shot that tastes/smells almost like the ground coffee smelled; and that's magic to me because there's nothing as amazing as how that stuff smelled. Most of the time, though, it just "tastes good". At the very infrequent magical occasions, that magical espresso matches the ground coffee more than a siphon from the same beans does. That keeps me digging.
Here's a low hanging fruit I hope people would point at only if they KNOW is the issue: I have a suspicion temperature stability during a shot plays a role. But then, how many machines out there have a razor-straight temp profile under the shower screen? My HX machine's, under shower screen, temp profile is "√" shaped: starts high, goes down over 5-7 seconds, then starts going back up from that point till end of the shot. The starting and ending temps are usually close and the delta from the highest temp to the lowest is something like 5+F. Again, please don't pick on this low hanging fruit unless you KNOW it is the issue.
