Some tips, one noob to another! I've been learning on a Carezza, but funding is officially here to pick up Anita + Max Hybrid next week! When that happens, we can compare notes, but until then, here's what I know from using my Carezza and voraciously reading everything about the Quickmill machines that I can get my eyes on.
1. What an espresso grind even looks like..
If you need to see it, there are good shots in the grinder forum and the Bench's Titan Grinder threads. But don't worry about that....take your grinder to zero (finest setting), then go up from there based on the results you get when you pull shots (see: question 5 below).
2. How hard I'm tamping with the crappy plastic tamper that seems waaaaay too small for the PF..
Throw it away. Buy a real 58mm tamper immediately. Makes a big difference. I suggest an Espro since it makes a subtle click when you hit 30 pounds - however, I have not used one and you can also just use a bathroom scale under the PF.
3. How to really do the HX flush thing....
Since you have the thermometer, don't worry about flushing by ear right now. Go to erics' threads about how to use the thermometer. I haven't used it, but when I get my machine, I plan to try the "flush to 196, then pull shot when the thermometer is back to 207" method.
4. How to use erics's digital therm to my advantage...
See above.
5. How to tell when I should stop the shot...
Right now, focus on getting 1.7 ounces from a double in 25-27 seconds. Keep your temperature conditions the same, and adjust your grind from the zero setting mentioned above until you are getting this amount in this time.
6. What a real shot of espresso even tastes like...
Strong. But without unpleasing/harsh bitter or sour notes. Either of these means something is going wrong.
7. How to steam milk...
Check out the videos on the site - I recommend Dan's video in the Alexia buyers guide. But the short of it for noobs like us is: put the wand a little under the surface of the milk - the sound should be akin to paper tearing. When the temp gets to 100 degrees or the side of the pitcher gets uncomfortably warm, fully submerge the wand's steam tip into the milk, stop when the temp hits 160 or the sides are too hot to handle & there's a roaring sound coming from the milk. Achieving microfoam is hard and I can't reliably do it, but basic steaming without getting dishsoap bubbles isn't really hard at all.
