Keep in mind, none of this may help you
directly, as we all have our personal preferences, and there are many products, tools, and even techniques that -- though different -- all will accomplish the same result . . .
I'm personally a big fan of
Bumper professional barista tools from Hong Kong -- I have a Bumper tamper at home and in my office, as well as a Bumper tamping stand (a
great, well-designed, and invaluable "assistant"), and knockbox. But that's me, and certainly Reg Barber makes some great tampers.
I prefer JoeGlo over Cafiza; it seems to foam less and rinses cleaner -- at least in my experience. After going through a variety of different brushes and cleaning tools, I finally got a Pällo brush and haven't looked back! I do have the wrench, too, but I can honestly say it hasn't been used much . . . yet. Haven't used nor needed "Steamy Wanda."
I have a digital scale that I use periodically (say, once every 1-2 weeks) as a "double-check" to make sure I am dosing "properly," and don't get into any bad habits. Same with a thermometer for my steaming pitcher -- once every week or two seems to keep me in line. I also have a variety of brushes -- see
here as an example -- if you count from the top left, I have #1 and #4 (as well as #7 in my office) to help sweep up stray grounds.
I also have some
Urnex Cafe WIPZ and, yes, Grindz . . .
Cheers,
