Well, a couple of weeks ago I ordered a Mini Vivaldi II and a K3 touch grinder to go with it. This is my first real espresso set up, so point of reference for a lot of things, or simply everything, is not something I have. So, when I say I am starting from scratch I mean it literally.
Packages came in about <1 week ago, but they had to sit in the garage unopened as I couldn't find a way to justify to my kids that I get to open my present early while they have to wait for days, which in their minds is an eternity and then some. Got to open them this morning and quickly set everything up according to the instructions attached. For some unknown reason to me, setting the volume for the double took me several tries to get it at about 60 cc. However, the one thing I do remain to get dialed in even after dozens of tries, 1.5 gal of water, and 1+ Lb of coffee beans later is the grind. I keep on going slowly bit by bit trying to get that 25 sec shot at 15-17 grm but I am far from it still. So much that I ran out of coffee beans. Obviously, I am trying this with crappy coffee beans I had here so I don't waste the "good coffee" I ordered with the machine. I am getting to a point that if I dial the grinder to a finer grind, it almost stops coming out of the chute. Before I get to that point though, the grinder takes quite a bit of time and several presses later to spit out 15-17 grms. The machine at this point is running about 6-7 PSI on the pump pressure (if that high) and running the shot in 18-20 sec. On a positive note though, with the naked porta filter I seem to be getting pretty even spread. This in my mind may not mean much of anything at all since the liquid if running through it so quickly it may be masking channeling to begin with. No crema either, which I am attributing to the crappy and extremely old coffee beans I was using to begin with. Also, I have not even tried a single shot yet!!
So, in conclusion after all the playing around:
1. Still cannot get the grind right. Any reference points in the Compak K3 Touch to start the dialing from? Could this be simply due to the ancient beans I was using? I am waiting for a store to open to go get 1 Lb of Folgers or something similar to dial in the grind and nothing else. I couldn't stomach that coffee to drink though.
2. Does the volume of 15-18 grm for a 25-27 sec espresso of about 60 cc sound about right? Suggestions to otherwise?
3. Why is the puck left in the porta filter after pulling a shot having a little bit of free floating water over it?
Of course, it has to be when all stores around me are closed due to Christmas that I need to go to one!!
