My shots and cappuccinos are finally tasting decent.
Part way through, when all was sour, and not knowing what else to do, I swapped out my IMS screen, and te-installed the Lelit screen.The flow slowed, extraction increased and I was on my way towards dialing things in.
Agree with MRS and CoyoteOldMan re-shower screen.
How did the coffee taste when you said dialed in? How long did the shot last? How would you score the coffee on a scale of 1 to 5 - the higher the better?
I am sure you are aware the decafs need a finer grind than the normal bag. I always prefer pulling short dealing with decafs - typically less than 1:2. What’s yours ?
How long do you rest the beans. I rest the decafs for at least 3 weeks.
I don’t really care about this; neither I know what a God shot is nor keen to know. All I care about is the coffee we make on our machines puts a smile our faces.
JHCCoffee Except that I will have to work through dialing things in again.
If you are swapping the shower screen to normal, why does it need dialling in? You have already dialed-in; grind at the same grind size and pull a shot using the same settings.
JHCCoffee And good points. What I have been looking for (and hope to achieve) is an espresso shot that has:
A nice round mouthfeel
Balanced (neither acidic or sour)
Complex (ie showing some of the underlying coffee bean notes)
With good strength
All while brewing decaf, as this older fellow cannot drink caffeine.
The “technical stuff” is how I am trying to get there, along with finding the best main ingredient (the beans) and using the right water recipe.
These are too many adjectives to what you consider as God shot or what ever you are chasing.
What grinder do you have? Without stirring a discussion of flat vs conical, a conical grinder and at least a medium dark, if not a dark roast, will get these - assuming you have the right parameters and dialed-in. You may try avoiding decafs that pack a fruity punch as they are likely to deny you the fully bodied mouth feel.
I think you should try not to blend the decafs initially, at least until you are happy with the shots.
CoyoteOldMan has asked a lot questions, which you need to look into and see if that helps.
