no, dual boilers much better - you did right

people just get ate up chasing perfection when theres so much variability in coffee

Decent De1pro v1.45 - Niche Duo - Niche Zero - Decent is the best machine ever made -

erkal - Unless you have a fully controlled and stable environment, a grinder that is 100% consistent and a coffee that never ages.

So it’s said that, for consistency, it’s best to control the ratio of the beverage over a period of time, but just roughly. Of course you don’t want for your 18g in, 36g out to last 50s nor 20s. But something between 30s and 35s is acceptable.

Maybe a Sage/Breville Dual boiler would have been a better choice for you, as it has volumetric capabilities. Saying that, I have no idea how accurate that volumetric flow controller is.

      erkal Hey! No unfortunately not. They are Americano drinkers. I cannot believe that the whole programming feature of these machines is just a fake gimmick. Why even bother putting these features in if they cannot work with consistency

      There are 3 other sources of inconsistency not being mentioned

      • grinder
      • puck prep and tamping
      • roasted bean quality/age

      If you do everything the same and are consistent in the 3 things above, then the volumetrics on the buttons should be right be within a couple of seconds or so.

          Keep an eye on pressure gauge also, readings must be different also between first and second shot. Pretty much we all had some sort of inconsistent pressure between first and second shots with Elizabeth.

          I have sent the upgraded opv but i never installed it, what i do now i place blind filter and run pump up to 30 seconds when machine is warmed up, then wait 1min to get it up to temp again. This is how overcame this inconsistency problem.

            This was a jamming expansion valve in earlier models, this is a late model one isn’t it?

                DavecUK Yes, jamming expansion valve i should have said. @erkal what is the production year of your Elizabeth’s?

                  Yeah it was an option but coming from a very very old first gen Sage Barista, getting another Sage did not excite me at all. I have just ordered a more accurate scale so that I can do it your way.

                    Hi Dave!

                    I mentioned my grinder being a bit less than ideal for now. It’s a Baratza Encore with Virtuoso burrs. I find the lowest setting almost clogs it so I move between a few ticks up and down just above the lowest setting.

                    I grind 19g and I get about 18.7, I then dump it into the portafilter. I then use the Normcore tamper with the lightest spring, I think this should be kind of consistent. I don’t have a leveler nor wdt tool.

                    Beans are from local roasters, I presume they are OK.

                    I hope this would keep it somehow consistent but sometimes the second shot is clearly visibly way too runny.

                      Inspector

                      The pressure gauge is almost always on 11. But I can definitely check again when I am doing back to back shots.

                      I am sorry I don’t know what an OPV is and I don’t know the year of the machine but it’s only a couple of weeks old, I bought it brand new from Bella Barista so I am hoping that it’s the latest one or I will be really annoyed LOL.

                      DavecUK

                      Is there a way to check the year?

                            erkal Is there a way to check what year it is?

                            You don’t need to they always have fresh stock, it probably won’t be very old at all, within the last 3 months of build date I would think. We’re talking more than 2 years, perhaps more than 3. @MediumRoastSteam how long have you had your machine now?

                                erkal I don’t know the year of the machine

                                There’s a rating plate at the back of the machine with information in it.


                                    It’s written olab 9-14 bar on the new type expansion valve and hexagonal part where I circled is quite wide compared to old one.

                                    erkal “Production 04/2022”

                                    2022? That’s a year old machine. Not that it matters, but it’s quite surprising.
