No offense but, I think some of you are jumping to conclusions a little bit and not reading my post closely? I posted that I used fresh coffee (it was roasted 8 days before I bought it), I explained the reason for ordering Lavazza was (which I know is never fresh) is general pop likes it and I posted some of the specs I am going by as I do understand the basics of tweaking grind, quantity, temp, brew time, brew ratio, consistent tamp pressure, consistent everything.
Where I need help is I think my brew ratio is not changing no matter what I do...always 1:3 or a little more. And my shots all taste very strong dark and bitter (funny because that description can be good too...even with a little bitterness)
I am measuring the beans with a .1g scale before grinding (dry cleaning grinder after each shot)
Preheat machine 30min prior to everything.
Preheat group head, portafilter, mug, by running 2 empty shots
Wipe PF & mug dry, grind coffee into PF stopping halfway to knock on counter, tamp approx 28lb / tamp ring flush & level with PF rim.
Lock single wall double shot basket PF in place, hit double shot button and timer on my iPhone
23 seconds shot stops
Instantly weigh the shot of espresso and watch the weight drop a little
(scale still set with cup tare)
2floz shot with crema
Crema looks good. Brown with a gold finish. Nice consistency too (not airy big bubbles) and the stream was even and uniform between the two spouts. Didn't blonde too early either.
Very strong and bitter, dark
I then rinse and repeat with changing the grind...same results or worse (although time may vary 20-30s)
Change dose up (all stronger, more bitter)
Always giving me a 1:3ish ratio?!?! Am I confused at how brew ratio is measured? Weigh dry coffee then weigh extracted shot?
I am a little confused at how brew ratio is controlled since mine doesn't change all that much between changes.
I tried a few 18g shots but this coffee is really fluffy and although I can tamp it just fine, I have to remove the PF and knock it or use my hand to level it 3, 4, 5 times to not lose it all, overflowing the basket so much.
Trying a different coffee (Lavazza) just to see if it i get similar results...if not, maybe the local roaster doesn't know what they are doing and so much for fresh coffee lol.
