You guys already knew it, and I already knew it. But I recently was forced to realize, truly, how important a good tamper is. Not even a great tamper, but a good one, will make your job easier and more consistent.
I work at a place where the shots can range anywhere from mediocre to great. The training is, to put it bluntly, inconsistent. People dose high, people dose low, people rarely dose *right*. The grinder is rarely changed, and before I came, the tamper was one of those two-sided aluminum clusterf***s. After my first shift, I brought in a $15 lava tamp that I bought at another shop in town, and instantly, my coworkers fell in love with me/it. I don't know which came first, but love anyway.
It was abused. Aluminum based, the thing had no choice but to dent and scratch and just get in miserable shape. And the plastic handle was begging for a crack.
Knowing that the tamper was eventually going to break, I ordered an Xpressivo Presso last Wednesday or Thursday. When I came in to work on Saturday, the handle was cracked, and on Sunday, the handle and the base separated.
I had to work two shifts with that two-sided aluminum doo-dad. Let me tell you, it is impossible to be consistent with one of those. You have to tamp 4 times with the exact same amount of pressure, or it's not right. It's harder to judge the amount of pressure you're tamping with when you have a "base" jabbing into your palm.
Sometimes, getting a new accessory (like a tamper, or grouphead brush) really can change the way you picture espresso. At least for me, it seems you have the two major building blocks down: espresso machine and grinder. The tamper acts as the conduit between the two. It translates the beans to an extractable mass. And every time I get a new tamper, I realize how important the tamper is, truly, to a good extraction. It's more important than the machine, but less important than a good grinder.
Try it sometime. Work for, say, a week with one of those double-sided aluminum things, then go back to your regular tamper.
I just had the nerve to lay out the most simplistic thing ever. But really, the tamper is more important than most people give it credit for. We're spoiled.
