GAGGIA CLASSIC PRO | OPV MOD DIY 9 BAR
HTML-код
- Опубликовано: 15 окт 2024
- Hi guys, we're sharing with you this quick video as we attempted to change the brewing pressure on our Gaggia Classic Pro. We wanted to achieve the ideal espresso brewing pressure of 9 bar.
We actually are waiting for our order of the OPV Springs MOD kit from Shades of Coffee, but just getting a bit impatient. We decided to do a quick DIY MOD with the manufactured spring, trying to get to the ideal 9 bar.
Warning Do it at your own risk!😄

Good video. I'd suggest using a proper closed end wrench though. Those slip joint pliers that you're using are notorious for chewing up threads, especially on softer metals.
Thank you for the advice, I’ve heard of it as well. It did in fact chew up on the outside. Wished I knew about it at the time.
I'm living in Ireland. LP Europicola cost €550 and GCPro cost €400. The money I spend for upgrading Gaggia, I put little bit more and I buy a machine for a lifetime ❤, beautiful and unique that involve me 100% to prepare my own coffee. And there is no plastic that touch directly with my water. What a big plus!!! I like Gaggia but sadly I can't change few major things.
Wow super jealous! LP Europicola would cost me an additional $400 here😢so I’m doing my best with GCP and just wait till one day when I feel ready for an upgrade😅 You should definitely share your experience with the Europicola later!
@@QTHomeCafe One day u will definitely have a LP Europicola. Till that time,enjoy your GCP it's a really 💎.
This is the best mod for Gaggia, I got my spring from eBay, I did not want to cut the original spring.
Thank you for this ... I have been contemplating this with my machine ... the before and after shot of shots simultaneously was so helpful!
Hi there, I'm glad this video could help. I also spent some time considering before giving it a shot. It's definitely one of the most needed mod for this machine.
@@QTHomeCafe yes I have heard that ... I am seeing more and more mods for the 9 bar spring ... all gaggia brewers should watch this ... your vids have a real peaceful feel to them ... very relaxing... thank you ... keep filming please :)
@@deniseg3562 Thanks so much for your kind words :) I do think coffee should bring us the calming and relaxing experience so I try my best to show it :)
@@QTHomeCafe you succeed indeed ... be well and drink great coffee :)
Thanks just cutted two rounds on the feather and works perfect saved med 22 GBP plus eventually import duties.
Good 'ol pliers on brass parts. Love it, love it, love it! 🙃
It was definitely scary doing it but that's all I have at the time! :) The one good thing about GCP is that you can purchase literally any parts of it from almost anywhere.
dearest, sorry for the inconvenience but I have an important question...I purchased the 9 bar spring which will arrive shortly...but after replacing it, can I still use the pressurized filter supplied (the one with the rubber underneath) or do I have to use it exclusively one of the remaining 2 (i.e. single and double dose)??? and if it's possible what happens to the coffee if I do it? Thank you very much❤
just came here to thank you for this video. I just changed my new GCP brewing pressure according to this video (but ended up 'cutting' 3 rings, as I initially didn't want to risk it with 2.5 as you said it gave 8-10 bars), and 3 works great. huge difference compared to original factory setting. much appreciation!
I’m glad that this quick video helped! It definitely makes a big difference. This modification is probably the best mod to do to any new GCP machine.
@@QTHomeCafe completely agree. I had read about this “issue” (not sure we can call it that, but …) online before purchase, and everyone’s recommendation. wasn’t sure how important it was until I pulled my first few shots. like night and day now, with the benefit of having more crema 🙂
again, many thanks for getting me back on track!
Not a problem at all. Just sharing what I’ve learned online too. Cheers! ☕️
Hi! I am aware that the expensive machines produce very little cream (CO2). We're you able to cut down the production of cream with the OPV adjustment and how much output of cream are you getting now in comparison to before the adjustment.
Thanks
Hi! Changing OPV didn't really affect my machine steaming capability!
Thanks for this video. U just convinced me to go for a La Pavoni Europiccola. The plastic water container is awful.
Haha I’m glad I could help! If you have the budget for it, then definitely go for whatever you personally prefer. Gaggia Classic Pro does have some limitations that I wish I could change!
How did you know cutting 2-2.5 turns would reduce the pressure to 9 bar? I am avoiding ordering a 9 bar spring and modify the OEM.
Thanks for the video.
Thank you so much for stopping by! I did some research online and a lot of people have tested it. Personally, I don't have any tool to measure but it should be around 9 bar. That's why I ended up buying from Shades of Coffee OPV spring kits to ensure that I'm at 9 bar.
@@QTHomeCafe OK, I just cut it myself today and I see a good difference between old pressure and new one. Even if it goes below 9 it should be ok ;)
@@QTHomeCafe Have you ever realized that the water in Gaggia's reservoir gets dirty very easily. This might be due to the fact that the reservoir is not fully covered. I haven't been able to find anything online regarding this. Kindly let me know if you have ever thought about it.
@@DarkKnight-yc8nw In water reservoir itself is not visibly dirty to me, I do take it out and scrub the inside once in awhile though. To me, it seems like the bottom of the reservoir is dirty from water and coffee ground spilling underneath the reservoir.
@@DarkKnight-yc8nw I saw some people just place a folded empty coffee bag underneath the tank to seal the gap at the top.
Does this in anyway change the steam pressure for milk frother? Sorry, I'm just getting into coffee machines..
Hi there! Any questions are welcome here and I will try my best to answer them! If you get it down to 9bar, it shouldn’t affect your steaming pressure. Anything lower, it may affect. 😁
I Installed the 9 OPV which is awesome. However I noticed when I go to steam milk I have been losing steam pressure. Have this occurred with you and if so what remedy did you use?
Hmmm interesting. I didn’t have any problems with steam pressure after the mod. I don’t think that should happen at all. Did you get it from Mr.Shades as well? If so, you should shoot them a message to see what went wrong🙂
Hi. Thank you for the video. I am a little confused. Marc from whole late love says that the pressure during brew process will be apx 9 bar ( not the static) with the original spring so we don’t need a 9 bar spring. Any comments?
I’m not exactly sure which video you are referring to but from my understanding, Gaggia Classic Pro brew around 12-15 bars OEM so it can brew for both pressurized and non-pressurized basket. I personally don’t have anything to test it. From my experience, it makes less channeling for when I brew and definitely help improving the quality of the espresso. I hope that helps! 😅
The standard spring for the GCP>2018 is calibrated at 11.5 bar. If your puck prep / grind / dose are all correct, you will pull shots at approx 9 bar. If one of those is out (e.g. overdose, grind too fine, ...) the resistance against the puck will rise until the puck breaks down and / or channels are created. Reducing the OPV to 9 bar makes your machine more forgiving.
@@motopasky Thank you. Makes sense
Could you give some context to that side by side shot at the end? Is that using the same grind setting for both shots? Or are you showing your best results before the mod vs best results after? Thanks and love your channel.
Thanks for checking out our channel! Both shots were done using the same grind setting and tampering. The only difference was the before and after mod. I did one shot right before mod and then pulled one shot after mod. The comparison at the end didn't do its justice, but the taste was definitely better. It brought out more of the coffee notes.
@@QTHomeCafe Hi thanks for the nice video. I have result like on the right currently and can't imagine how it will be after the mod. Same as you, my Mr Shades kit is currently being inspected at customs:)
@@muratozt thank you for checking it out😊keep me updated on how it works out for you! I’m curious on how it’d change on the taste for you
@@QTHomeCafe I will. Also bought bottomless portafilter for checking channeling issues. Lets see
Hi, today I installed the 9 bar spring. I used bottomless portafilter from Mr.Shades (which arrived together with the kit) to check the extraction and the flow was flawless. I made no change to grind size and tamping pressure and can tell you without any doubt that the pressure modification made a remarkable difference to flow, extraction and taste. I also see that the extraction is not as sensitive to other variables as it was before. So more consistent results should be expected.
What change did you notice from lowering the OPV?
Hello! It helps reduced the bitterness when I extracted the espresso shots. Makes it a little bit more enjoyable.
@@QTHomeCafe Thanks for answering my question. I will be lowering my GCP to a 9 OPV. I have a Baratza Sette and have my grind settings dialed in for my different coffee beans. I was wondering when you lowered the OPV, did you have to reset your grind settings on your Barraza Sette?
@@mrgoldenginger I’m glad to hear that! Changing the OPV to 9bar is definitely one of the must thing to do on Gaggia in my opinion. I will suggest you do what you would normally do and go from there. Every beans are different but it shouldn’t be that much of a different in grinder setting.
Why does it produce more crema and also how is the shot starting earlier if the pressure is less I’m a bit confused about that
The comparison video at the end was very bad. It was the only footage at that time that I had for before and after. I didn’t even line both videos up properly. 😅the timeline between the two is off
@@QTHomeCafe just messaged you on Instagram :)..... but hey I’m wondering after you did the change did you notice a difference in the crema? I noticed on mine that the crema doesn’t have that pretty falling look like a nitro beer does and I’m wondering if it’s because it’s 11 bars. My coffee is super fresh and the timing is good so I’m a bit confused. I will say the machine is brand new less then a day old so maybe I need to run a bunch of water through it first or something
@@JoeyVaracalli it will definitely help with the creama if you lower the brewing OPV to 9bars. Not only did I notice the difference in cream, but also in the espresso shot taste in a better way (reduce the unwanted sourness from the shot). 11-12 bars of pressure from manufactured is a little too high for freshly grind coffee beans in a non-pressurized basket. It could damage the coffee puck and create channeling which result in bad espresso.
I found the coffee always bitter after cutting opv spring, cause it increase exaction time and get more unpleasant flavor, solution is to grind courser a bit or reduce exaction ratio. Any suggestions for better results?
Sorry for the super late reply! How’s your coffee journey at home?
It is good now. Just found out the right grind size. Thanks
Why cutting the original spring :\ when you can buy online for 5 bucks pre-calibrate spring.
😄It’s called impatient haha. I did buy online but was just eager to try while waiting for it to arrive! A bit experimenting
I'd be interested to see a link for a $5 pre calibrated spring...
@@motopasky Ebay
@@niraviv8431 12$ for a spring. I just bought one.
Why pay $5 when you can cut the original spring? Or.......you can pay $30 for a $0.00000000001 chinese spring and feel good about relieving your wallet of some weight. I understand though, thinking is hard work and who wants to do that, right?!
But doesnt the classic pro already brew at 9 bars?
It's actually brew from 12-15bars depend on which year you bought the machine. If you have the opportunity to, I would really recommend you either buy an OPV springs kit from Shades of Coffee or do a DIY.
@QT_HomeCafe but why does it brew at 11-15 bars? There must be some engineers who have designed it this way? Maybe it’s better in this machine, since they made it like this?
@@DonQuixotec There's 2 type of baskets that came in the box, pressurized and non-pressurized. Pressurized basket (a basket with a single hole in the middle of the basket) is a basket where you can use E.S.E or pre ground coffee to get a "fake" version of espresso. It requires higher pressure to brew in the pressurized basket hence the 12-15bars. Non-pressurized basket is a basket where it produces a true cafe espresso. It requires a lot more to make it a tasty shot but it will produce a much much better shot. The ideal brewing pressure for a non-pressurized basket is around 9bar. If you do use 12-15 bars to brew non-pressurized, it can create more bad shots than good shots and that's not ideal.
@@QTHomeCafe Thanks for clearing that up with me! :)
@@DonQuixotec no problem! Are you currently using Gaggia and Sette 270?
Where did you buy OPV?
I got it from Shades of Coffee 😀
@@QTHomeCafe Hello have you tried the 6.5 bar from Shades of Coffee? I guess it comes in the same bundle.
You can adjust brew pressure simply rotating clockwise the brass conector wich contains the spring inside, I don't know why everybody are cutting or ordening another spring when all the opvs contains one spring like that and they get adjusted simply loosen or tighten that spring, like in rancilio Silvia, this gaggia pro OPV is the same! That bolt don't get to much pressure wich could produce leak's and in that case you you'd simply apply some teflon and that's it!
@@eduardocereceres2949 I actually have heard that too but unfortunately that only applies to Gaggia Classic (pre 2018 model) and NOT Gaggia Classic Pro (after 2018 model). Thank you for sharing your tip though!
@@QTHomeCafe hi days ago I adjusted my gaggia classic pro that way and it is 2020
Thanks for this. I just did this on my new GCP. Cut off three turns of the spring. Now it's time to start over dialing in the beans I've got.
No problem! How was the result after you cut off the OPV spring? It's definitely one of the most needed mod for Gaggia.
Great! 18 grams in and 38 out in 28 seconds! It always ran too fast before.
@@danjv that’s very nice! How’s the espresso? Did it improve the taste?
Tastes much better but I'm still searching for the right temperature.
It’s hard to be consistent without a PID but it’s doable. If you wanna minimize that guessing game then you should look into installing a PID 🙂
I’m first
haha I appreciate it! :)
