June 2014, Update: Original article below for reference, but here’s my current settings. I am now using Revolution Roasters Smooth Operator blend. My grind setting is 8D AFTER calibrating my Preciso to use the second finest calibration. I pull a double by grinding for 10 sec, tapping the portafilter down twice, then grinding for an additional 8 seconds, distributing, then tamping.
To brew, I turn the brew switch for 6 sec, then off for 10 sec, then on for 26 sec. The shots are uniformly smooth, rich and wonderful.
So, I’ve been messing with my De’Longhi EC155
for 2 months now, and I’m to the point where I’m really happy and am consistently pulling a good espresso shot. So, I thought I’d share with you all. Here’s a little video I recorded of how I do it. You can flame me all you want for the way I’m temp surfing, or that I’m using Lavazza Tierra!
beans, or whatever. But, I’m producing a consistently good espresso shot this way. So, if you don’t like it, go make your own video.
Oh, and if your wondering, this is the tamper I use.
