Absolutely Positively Better Consistency!

Post by mdreuben »

Three days and many shots later I'm totally convinced that this is really the way to go. The shots are scarily consistent. Even to the position of the stream as it comes down from the bottomless portafilter. I'm at 30psi and 3 seconds pre-infusion.

Could not be more pleased!

I'm at 6 seconds at that water pressure and I'm lovin' it.
I guess it depends on the coffee used.
I'd like to try 45psi with 4 seconds but it's too much work to bend over and change the pressure :lol:

I ran my first shots today since the upgrade with the P/I set to 3 seconds & 25psi flow rate. Dialing in some of the Konga Co-Op Yirga N.I. from Terroir. Too soon to say much as I've never had this Espresso before so can't comment on taste improvements. The pour through the bottomless p/f didn't seem much different then I've been seeing but I'll do some back to back with & without p/i tomorrow to see what differences show up.

Dialing in some Kid-O today with 3 second delay/25psi. Best tasting shots were after I turned off the P/I. Haven't seen any improvement in the pour with p/i either. Just the opposite really. Any thoughts??

I've had no problem getting 17gr+ of Kid O in the basket so 16gr shouldn't be an issue. Flavors are supposed to be Caramel with a hint of nuts according to their description. I've gotten a nice sweet caramel a couple times but also what tastes like bitterness more often then not after you get past the crema sip. Tried 93*C/15.5g/17g, 92*C 15.5g/16g+, 91*C/15.5g. 92C seemed to be the best but no real consistency so far.
