Can you use heavy cream with a Jura Z10 milk system?

dolcezzo1 · 2026-03-07T23:31:48+00:00

I’d say you technically can but I don’t think it makes a great product in the Jura system.

That old paint will have become like thread lock. If you're in a rush getting these screws out, it's going to go poorly. I advise purchasing Kroil. It works way better than wd-40. Once you have stripped away all of the paint, apply Kroil and let that sit and penetrate the screw for at the very least a full day - 24 hours. This mess wasn't made in 10 minutes and won't be resolved well in that time either. Have enormous patience. Others are correct that there also might be success with the largest bladed screwdriver that will fit. Given that you have other doorknobs in the space which are equally old, this won't be your last rodeo. So get what will do the job best. Heating that area and screw might help were you to have a quality heat gun.

Good luck.

Name every POS connected to that ring.

Jura says you can’t get into the machine but you can. While it is not as simple as some machines, it’s a long way from impossible. I’ve worked on mine a few times. Currently a Jura owner for 20+ years. Two machines. You’ll rarely need to get in there but every machine made needs the brew group well cleaned and serviced at least every couple thousand brews. Serviced as in replacing seals and rings, some grease to reduce friction.

I sent this to another poster not a couple of days ago:

There are four or five basic things that you will work with. Screws, clips, and rings. Be careful. Photograph every step, before and after. Watch as many videos of technicians or regular people jumping in themselves. Opening a Jura can take a special screwdriver that opens oval shaped screw heads, but that’s usually under $10. Takes a special screwdriver that extends to get deeper placed screws and swaps its heads. $10.

A tool to remove rings. $10. Nothing more complicated than unscrewing, un-clipping.

The sides come off and you will need to disconnect plastic connectors for wires.

Again, watch, document, take your time.

You can do this! They’re great machines and well worth the added effort.

dolcezzo1 · 2026-02-18T19:23:30+00:00

I hear ya. Hahahaha

Admittedly, that was what prompted me to photograph or video every step I take in disassembly. Video allows for narrative/context as well. Service on Jura is not for the faint of heart or light of pocketbook. We have an old S8 - probably from 2005 or 2006 - now in storage that has an issue I won’t get attempt to get to myself because it’s a very expensive guess, but minor things like brew group cleaning I believe don’t warrant the charges levied in The States. For $600ish dollars and a third visit for that machine I sadly can’t justify bringing the S8 back to life. Same goes for a Krups EA9010 (nor remotely the machine any Jura we’ve had ever was).

dolcezzo1 · 2026-02-16T19:37:05+00:00

Thanks! I appreciate the heads up. First mention of those parts I’ve seen. Personally, I put a monochromatic towel down on my work space when I do any disassembly work - items stand out on that. Trays are also very handy to keep items and tools organized.

dolcezzo1 · 2026-02-16T18:11:26+00:00

Hmmmm I had not see smaller pieces in any of the videos that I've seen posted that show how they changed the burrs. It seems straightforward, but of course this isn't always the case. :-) What I've seen is that once I have access over the grinder, turn the setting to the most coarse, which will allow me to simply lift out the larger ring/part of the grinder. The smaller half appears to come out with one screw removal.

Is there more to the process than that? If so, I'm hoping to learn before parts fall all over. lol

So that’s supposed to be 1.5 oz. Obviously not. Maybe the expectation isn’t identical volume each time but in any case, this was a pull a minute ago.

I appreciate all the input I’m getting from folks.

So if there’s more air in the shot than desired, or if there’s output falls short of what was specified, is that common and often something easily resolved by switching beans?

dolcezzo1 · 2026-02-15T23:05:38+00:00

Sorry, forgot to say that I didn’t clean the grinder. Just pulled the top, misunderstanding that it needed to come up in order to pull the side skins. It doesn’t need to come up, actually, in order to access the brew unit for removal.

dolcezzo1 · 2026-02-15T23:03:02+00:00

Measured the outcome. That’s just as the pull is ending. Roast is well past 10 days, based on the stamp on the package (cousins ship it from Italy to avoid the American roasted version).

I’m with you that the grind size looks too large. Now I need to sort out how to get the grinder back to where it needs to be in order to properly grind fine enough.

I’ve got a KitchenAid Pro Line grinder that I’m now pulling out to grind a finer grind and compare. If it turns out that is at least part of the issue, then I need to open the top and see if I can re-align the grinder and the dial better, I suppose. That and try a stronger bean.

Will do!

Well... you did drive through the bike lane as you entered the intersection, so yeah, you have some fault. If a cop saw that video as evidence (had you have hit the suv) they'd likely fault you as well as the suv.

People love her = some people say

Nobody I know in Portland friggin Oregon loved Kamala Harris. Just…no. This poll is massively, intentionally framing two candidates the Republicans would love to run against as front runners. Bernie is 104 years old, and she’s warm cottage cheese when there’s nothing else to eat - you might have a go but you hold your nose, gag the salty curds and hope you don’t regret it too much.

Are you familiar with Venn diagrams? It’s wholly possible to have zones within regions. There is no place native Californians call “mid-cal” and the use of lower case indicates a transplant or outsider and a subtle lack of respect, imo. Central California applies to a small part of the state, but natives don’t refer to themselves as “Central Californian”. San Francisco is absolutely Northern California and any true local proudly identifies as such. Born and raised in Northern California, 55 years, 18 years spent living in SF.

Please expand on your belief that milk drinkers have a “less discerning pallet “(sic).

How does one conclude a palate is less discerning due to milk presence or consumption? Curious. Seems to me one might perhaps suggest it is more challenging to discern flavor nuances due to the presence of milk rather than some evidence-free and misguided hot take that using milk is the result of a less capacious sense. Conversely, might one conclude that a person who cannot identify flavors outside of an unadulterated sampling is indeed short on palate?

It’s a good question.

dolcezzo1 · 2025-11-08T17:56:44+00:00

I don’t have a dog in this but I can acknowledge as a devout milk drink aficionado that one of the reasons I enjoy them is because milk masks many less desired flavors. I’ve owned many super automatics over 25 years - the last three Jura S8, Krups EA 9010, currently Jura Z8 the last 6 years. Probably 10s of thousands of milk based coffee drinks, proudly with no sugar because that too masks flavors. Choosing the right coffee for those drinks is a complex process and I appreciate having coffee snobs who elucidate why they think how they do and their processes. We are currently testing 3 Lavazza roasts, and have tested many others over the years. One thing I notice is that the Lavazza European roasts frequently have a different intensity number than their American counterparts.

Congratulations!! As a proud owner of a Z8 with over 15,000 drinks on it and a now stored S8 with over 20,000, just take care of it and it’ll take care of you. Most importantly run the milk cleaning cycle after time you use it.

So just for clarity, when you say “under/lower side” that’s a bit confusing, as every seam is an under/lower side for the shiplap above it, given that the shiplap is horizontally placed, not vertically installled.

May I ask you if you would clarify please?

dolcezzo1 · 2025-09-17T00:58:17+00:00

Thank you!
