I had that Espro tamper. I bought mine new. No audible click, but there was definitely a feel of a click-like mechanism, and it was (according to Espro) set for 30#. I usually pushed right through it. I had it a long time before I took my barista training class at Klatch back in 2009. when Heather got out the bathroom scale to measure our pressures and show us what 30 pounds felt like, I rang in at 60#...so much for the Espro clicky device! Obviously, I stopped using it. I've been tamping pretty lightly the past couple of years. No longer do I get into the action of really compressing the puck. Rather, I give it a decent tamp and go by feel of the grind compression, as soon as I feel it's packed in a bit I stop. I start by pushing lightly while my finger tips feel the edge of the portafilter and I check it for level by feel this way. Occasionally, I bring it up to eye level after to check for a tilted tamper (from multiple angles), but when it feels right, it tends to look right on further inspection, so I don't do it that often. OK, I have to confess, I stole the finger tip part of the tamp from watching a video of Chris Nachtrieb on his website. Once it's level, I apply a little more pressure just until I feel the puck is compressed - no more. I'd guess I'm probably closer to about 20#, but as we keep reading here, over and over...I'm consistent...and my shots come out great.
Yup. Both good and bad information get propagated via discussion forum sites. Always consider the source -- both the person and the age of the post/thread. As others have stated, if you limit yourself to recent threads here you'll see that consistency has been the mantra, not specifically 30 pounds as in the old days.
