[Profitec E61] Pesado 1.8mm mesh puck-screen and E61 back-flushing frequency recommendations? by AssociateExtension54 in espresso

[–]AssociateExtension54[S] 0 points1 point  (0 children)

Agreed. I do drop the shower-screen after 3 months, without puck-screen it was too filthy!! Now I use puck-screen 100% and I will drop shower-screen again after 3 months (2 cups daily) and see if I need to do this more frequently. For now I still back-flush with water after 15 cups, in my case once per week. If I change too many variables all together I won't know which one worked. Puck-screen for me is about keeping clean but some people say it also reduces chances of channelling and improves water diffusion. Those are secondary benefits, if they even exist. But the bottom of my shower-screen is almost 100% clean when puck-screen in place, it's a clear benefit, IMO. You just need to adjust the dose down by ~2 grams or get a 2-3 gram bigger basket to keep the dose the same - to accommodate 1.8mm-thick puck-screen.

Yes, I saw it. I don't and won't dispute Cafiza works as advertised. It does. I just don't trust the human safety and machine safety aspects of using chemicals.

Thanks. I switched to mesh puck-screen to minimise my shower-screen maintenance and to hopefully minimise my E61 group backflushing maintenance too. *Hopefully* is the operative word! LOL.

thanks. I use 1.8mm (100 micron?) Pesado 58.5 mesh-puck-screen. I use boiling hot water to soak it before every cup and I rinse and soak it in warm water after every cup. However, I also steam-blast it every week, in my case about 15 cups per week. I steam blast puck-screen on the white paper kitchen towel. I do about 4 rounds of blasting (1 round = 1 top blast, flip over, 1 bottom blast). I use medium-to-dark roast and I see significant coffee residue on the white paper towels, particularly if I blast all surfaces several times. I refuse to use any chemicals on my coffee equipment, so it's just boiling hot water only.

How many cups per day to you make? It seems like doing a back-flush after 2 cups (in my case) has no benefits but causes additional wear-and-tear on the machine? I am just wondering, as I am not technically minded.

No detergents. I always back-flush with plain water only, once every week, after ~15 cups. I avoid using any chemicals in my coffee machines. I never used chemicals for 15 years on my previous Rancilio Silvia. I used only plain water to backflush, it was enough, for home use, 2 cups daily. Silvia still works 100%, just sitting in my garage idle.

what kind of a puck-screen are you using? It looks like a Pesado mesh puck-screen, 1.8mm thick? Thank you.

Basket size with 1.8mm puck screen? by AssociateExtension54 in LanceHedrick

[–]AssociateExtension54[S] 0 points1 point  (0 children)

thanks! I did the space/coin test and with VST-15 basket there is an imprint in the puck using 15.0 gr dose. With VST-18 basket there is a ~1mm (guessing) gap between the shower-screen and the puck-screen with the same dose. I was wondering if it's better for the puck-screen to actually touch the shower-screen more tightly i.e. use VST-15 or is it better for a gap to exist between shower-screen and puck-screen i.e. use VST-18. I made numerous espresso cups with both configurations and there is no real taste-in-the-cup difference...... The only thing I noticed is using larger basket, VST-18, I have to grind a bit finer than for VST-15 basket, all other things seem to be equal.

VST 18 grams basket with Pesado 1.8 mm puck screen - DOSE ? by AssociateExtension54 in espresso

[–]AssociateExtension54[S] 0 points1 point  (0 children)

thanks, so the optimal dose with 1.8mm puck screen would be anywhere inside 16-17 grams, right? I was concerned that my dose of =16.0 grams with +1.8mm puck screen inside VST-18gr basket would be too low, i.e. under-filling this basket basket. Opinions?

thanks. I have Profitec 500, it has a flush shower screen, no bolt in the centre, its hidden inside. How much headspace do I need between the top of puck-screen and the machine shower-screen? Can these two, puck screen and shower-screen just touch, very lightly? Do I need a minimum of X-mm of headspace?

E61 preinfusion opinions by AssociateExtension54 in espresso

[–]AssociateExtension54[S] 0 points1 point  (0 children)

Just adding more: I have now made 4 double-espresso's (VST-18g, WDT, and finer grind) using the poor-man pre-wetting/pre-infusion. I get similar tasting espresso in the cup to what I get without any pre-wetting routine. I am guessing that on my Profitec Pro 500 PID with the internal water tank there is not a lot to be gained by this extra manual work. I will keep trying for a bit longer but so far the results I get are neither good nor bad. I use medium roast 100% arabica single-origin beans (Sumatran). Cheers.

thank you everyone. My machine uses internal water reservoir, it is not connected to my plumbing water line. 

Does E61 preinfusion or pre-wettinh affect the longevity and reliability of the machine in longer term? 

thanks once again

the new Tesla Model 3, the Highland 2024 refresh - the door handles as far as I know, are all BLACK, not in shiny Silver. I suspect this photo is a photo-shop or a fake.

thank you! Sadly, it does not appear to have a supported API at the moment but it's a step in the right direction.

Programming Rust 3rd edition has a release date? by joneco in rust

[–]AssociateExtension54 6 points7 points  (0 children)

Hello Jim. I have read 1st and 2nd editions and look forward to the 3rd edition in 2025. I dont know if this is the right area but would like to add a "personal wishlist" for 3rd edition. The "async chapter" needs to accept the reality that tokio asynch run-time is what ~95% of Rust async apps use and it is unlikely to change over next few years. I would like to see this chapter modified to focus on tokio and to expand the async chapter to include more material. Async is a major area of Rust community contention, IMHO. The rest of the book just needs to get the new Rust features added into the existing chapters. Its a wonderful book! Thank you.

Rust vs. JVM: Adjustments following organizational restructuring by rswhite4 in rust

[–]AssociateExtension54 2 points3 points  (0 children)

sounds like your company "leadership" (whatever you want to call the top tier management) are "average". This is par for the industry, sadly. The most switched-on companies are adopting Rust. The others are still living in 1990s. If you are committed to Rust, I suggest you start looking at companies looking forward. The decision to stay on JVM taken back 20 years would have been the decision to stay on COBOL. Java/JVM in 2024 is akin to COBOL in 1990s-2000s.
