Specificity builds credibility. John, the detail with which you talk about everything that went into this change demonstrates how committed Decent is to excellence. Bravo.
This video is exactly why I chose a Decent machine. People obsessed with improving at any level, any part, something that just works consistently great. Outstanding work and yes I already upgraded the group head with these parts. Very easy and no need to flip the machine at all. Saludos !!! 😎☕️
It's funny to see John's focus mirroring my own espresso journey where I was messing around with light-roast single origin new wave coffee for awhile and now I'm just chasing the perfect classic italian style espresso.
Just installed my new group head parts! I can’t wait to test it more. Today it seemed to have a tiny bit better balance and maybe after looking at my rusty looking brass it will keep way cleaner so maybe that is a cleaner cup with less old oil since I only back flush like every three weeks. The puck is still a little soupy but no big deal.
Hi John, thanks for mentioning the relationship between body and headspace. Can you comment more specifically on the improvement in body the new configuration provides for classic-style shots? Specifically, I’m curious how body from the DE1XL would compare to that from a Linea Mini for medium or medium-dark roasts ground with conical burrs and extracted with a flat 9-bar profile. Thanks for your time. -Dan
Is PPS at any time capable of leaching antimony or BPA? or any other known chemicals known to possibly harm humans? I ask due to the amount of heat this part will be exposed to along with the fact that what passes by/through this part will be consumed.
I've been having channelling issues with my gaggia machine where the extraction is too fast and the puck is dry on the bottom. I think a dispersion screen might help. Please invent one to fit my gaggia machine!
Very cool. Are these fitted as standard now? Just ordered a machine today, and would be curious to know if this will be installed. Great work as usual!
If your machine hasn't shipped yet, the new parts are available as a CUSTOMIZATION for +$100, and we'll do it for you. But... I see your machine HAS shipped, so it has the brass parts inside. You can get the parts from us at $100 and install them yourself. decentespresso.com/accessories
You may have confused this info with the new PPS parts that have just been released. Installing these parts will match the headspace in a E61 grouphead.
Yes, we continue to use the IMS SI200 screens. Yes, the $100 goodie pack was an introductory promotion for the extended warranty, and the offer ended about 2 weeks ago.
@@decentespresso this is a pity, I did not purchase the warranty yet because of this option. The DE1 comes with a CI200 not SI200. Please do not confuse.
Does the "Group head v2 upgrade kit for DE1 v1.1-v1.44" part include both this and the lower headspace? Or should I wait for an upgraded kit? Many thanks and awesome continuous innovation! ❤
This will lower the headspace but you will also have to be mindful of the gasket you are using and or the basket and dose, which also affect the headspace.
@@huachangxu7655 he says that the MAIN POINT of using plastic and not ANY metal is due to the temperature lag caused by the metal acting as a heat sink. The move to plastic is largely to get much faster and more accurate response to the actual temp in the group head. So any metal, brass, aluminium or stainless steel would have the same negative impact.
To compensate for the brass heatsink effects, can't existing brass-users to change their algorithm to have +3-4 degree pre-infusion temps? Or another question, if you switch to the new plastic group head and your same recipe "instantly tastes better", it means the original recipe wasn't good enough and should have used a higher water temp.
He implies that right near the end around 14 minutes in . They are reducing the space between the shower head and the puck which should result in drier cleaner pucks.
yeah it's mentioned in the description of the video: Reduced channeling: Less headspace above the coffee puck reduces channeling and increases mouthfeel and shot consistency. Also says it at the end of the video. Same as E61 machine.
It seems to help a little after one shot today. Nothing like a dry puck.I will do a video on it. I think since it doesn’t have a traditional three way solenoid, it doesn’t do a large suction that a 9 bar machine would so after a shot turn on and suck the water away so maybe that’s why it’s not as dry.
@decentespresso Honestly I’d rather see you make them out of copper or ceramics composites make it either highly sensitive to heat or resistant to heat over time I see the water slowly eroding those parts into the cup and I’d rather not drink plastic but that’s just me I don’t care if some bureaucrats say is safe Also the sticking of the oils is from the copper in the brass it’s one of the reasons copper is used in alcohol distillation it’s reactions to oils for example a still that’s made anything but cognac can’t make cognac because the copper has been contaminated with oils other than what would be found in cognac and would not created a suitable cognac flavor profile The change in flavor could be the heat or it could be the oils not reacting with the copper in the brass acting like a catalyst this is important in distillation to remove sulfur compounds but it might be harming the depth of flavor in this process
and yes, we'll continue to stock the brass parts, for people who don't like the idea of any plastic in the water path, even one so well tested, used by so many espresso parts companies, and used to make baby bottles. You're welcome to use brass, if that's your preference.
My brass parts were starting to very slightly erode a little with some surface rust and I wonder if they have a tiny bit of lead. I guess this is probably just as safe or safer and way less cleaning is needed.
Machine has been great so far, but the customer service has become suspect. Decent made an offer to customers, then without proper announcement withdrew it before this promised new grouphead became available. Terrible decision.

Appreciate the indepth reasoning for the design change!
Amazing! This is innovative and progressive. Can't wait until it's available
It's available today decentespresso.com/accessories
@@decentespresso Got it a few minutes after it became available :)
Very happy to have this level of detail. Also loving the video production quality
The Greatest Upgrade kit EVER
Great explanation! Thank you for creating this video.
Just installed my new group head parts! I can’t wait to test it more. Today it seemed to have a tiny bit better balance and maybe after looking at my rusty looking brass it will keep way cleaner so maybe that is a cleaner cup with less old oil since I only back flush like every three weeks.

Amazing work!
with this group head no extraction without channeling!
with the previous group head I hadn't such problem.

Love it! Do I spy a Decent Scale in use behind you ;)
I've been having channelling issues with my gaggia machine where the extraction is too fast and the puck is dry on the bottom. I think a dispersion screen might help. Please invent one to fit my gaggia machine!
is that means the existing pour-over basket will not work for this new parts anymore ?
Are all new machines fitted with these new parts?
Are these changes incorporated into the v1.45 that’s currently on sale?
Will this get us to exactly being able to match lever style espresso?
No
Can this fit a LMLM
Besides obviously removing the tanks, anything else needed with the machine or just flip upside down after removing those?
We also recommend using a towel so the top of the DE1 is protected too while on the table surface.
Are there any non-torx screws left on the DE machines?
A few inside, holding the PCB shielding panels, for instance. But not many!
John, I would love to know your personal opinion on whether a puck screen interferes with this sensitive process, thank you so much
*whether or not
It'll obscure temperature readings, yes, but will give you a drier puck. Let the taste be your guide.
@@decentespresso amazing thank you.
Is this fits the breville dual boiler bes920?
Apologise, this part is only compatible with the DE1 series.
Very cool. Are these fitted as standard now? Just ordered a machine today, and would be curious to know if this will be installed. Great work as usual!
You will still have brass internals on your new DE1. We plan to have these released soon and they are backwards compatible, so no FOMO! 🙌🙌

If I recall correctly, v1.44 already had a change to decrease headspace. Does this make 1.44 machines lower than E61 spec?
You may have confused this info with the new PPS parts that have just been released. Installing these parts will match the headspace in a E61 grouphead.
Does the PPS have any Nylon reinforcement or is it Natural PPS? Where can one find the E61 headspace Spec?
Hey, these are pure PPS material, which is the same material as baby bottles the most tested plastic in the world!
We measured E61 shower screens, to find the size.
Will the decent eventually be free of brass or use eco brass instead?
As mentioned in the video we are looking to reduce this material moving forward for more advantages materials.
Can any of these parts be used on a non-Decent machine, such as a Breville?
Unfortunately not I'm afraid.
hi john, will this new design also work with IMS SI200 shower screens? And did you drop the 100$ goody in your 2-year warrenty option?
Yes, we continue to use the IMS SI200 screens.

Any plans to make these in stainless steel?
dude, watch the video
@@decentespressoailliobullet5748 dude I did, twice. There's no mention of a stainless steel option. Timestamp?

It's more complicated than that. The brass contributes latency, which causes many effects. The video explains more.
Will the new group head reduce the soupy muddy coffee sludge and dry pucks?

Also the sticking of the oils is from the copper in the brass it’s one of the reasons copper is used in alcohol distillation it’s reactions to oils for example a still that’s made anything but cognac can’t make cognac because the copper has been contaminated with oils other than what would be found in cognac and would not created a suitable cognac flavor profile

Fda aproved tefal as well, and how many people had died since.
Thanks for the public notice, you can still use the old part...
and therefore?

Decent is the Tesla of espresso machines. I am about to jump from à Londinium L1 because it’s simply a one trick pony that is not consistent.
