I'm very frustrated now.
I want to give back the machine. The supplier in Paris that sold it to me was recommended directly by Quickmill.
Any last ideas?
Once in a while, by accident, a user with a new machine hits a "god shot" the first time - then spends weeks trying again and again to repeat it. For me, it took ten to twenty shots a day for two or three weeks in order to get reasonably good coffee consistently. Then for no reason (it seems) you go on a "down" cycle for awhile. You have lots of variables to control, but, for me the five most important were fresh coffee, grind (including the grinder) distribution, tamp and temperature. Very dark coffees, particularly if they are not completely fresh, are the hardest for me to do right.
I'd want to get a naked portafilter to analyze whether I am getting grind and distribution right. I have a favorite roaster who roasts really dark, his coffees take the most technique to get right.
I wonder if there might not be a roaster in Paris from whom you can get beans that are only a few days old. I've never had a "canned" brand work correctly.
If you're not getting some "joy" from the adventure, maybe something like a Nespresso would work better for you. I've never had espresso at the level I can produce it from them, but I've had acceptable cups. I got one for my son, because as he says, "Dad - I just want to step up to the machine and have it make it. I'd never do the fooling around you do." What's kind of a challenge for some of us, is drudgery for others. If that's true for you, Nespresso (or something like it) could make sense.
