Three weeks with the GS3
I have had the GS3 for almost four weeks now. Time really has gone quickly. So how are things? How is the GS3?
I have to say that I am impressed. My coffee has gotten and keeps on getting better. The feedback given by the machine is certainly a large part of this. For example, the combination of the Chronos -function (essentially an elapsed shot time display) and the brew pressure gauge immediately gives me an indication on how close my parameters are to the ideal.
The shot was too slow? Ok, adjust the grind. Shot time, volume and brew pressure were spot on and the shot also looked nice, but tasted bitter? Ok, just dial down the brew temp a notch or two. This is just so easy to do with the GS3 and it also turned out to be a very useful feature over the last couple of weeks when I have been trying seven different blends of varying roast degrees. Great!
However, I have noted that at least with the current pre-infusion settings I have, the GS3 is a tad less forgiving of sloppy distribution technique than my Andreja. I will keep on trying different settings here, but I think that this machine also reveals the small distribution issues that the Mazzer Mini-E grinder has (the particles of different sizes are not spread equally into the filter basket). So, one just has to take a bit more care in his/her barista technique, which is not a bad thing. Having said this, I have been researching grinder upgrades for quite some time now and I am closing in on a decision. It's not that the Mazzer Mini is a bad grinder, but I want something that is of the same caliber as the GS3...
I reported earlier that I have had some problems in steaming milk. I hear that La Marzocco is addressing this issue and I am keenly awaiting news on this front. My latte art still isn't as good as it was with the Andreja, but I am not yet sure if it is a wet steam issue or just down to me needing more practice (it took me a good few months to get it right with the Andreja).
In the meantime, Kaffecentralen in Finland kindly sent me a selection of steam tips that I could try and it turns out that a couple of them actually do a very good job. Of the tips pictured the three and five holes ones in the bottom row are the ones that currently work best for me. I like the five hole tip because it is easier to keep clean, but the three hole tip produces slightly better microfoam. I'm hoping to get one of the LM three hole steam tips soon.
So in short, I am already very happy with the GS3. I hear that the last minor niggles are in the process of being sorted out in the near future, in which case I believe the GS3 will live up with the very high expectations that people have put upon it. Thank you La Marzocco for building the GS3 and thank you Risteriet for getting me my machine!
By the way, La Marzocco has updated the GS3 product pages, which now look pretty impressive. Also added is a Q&A section that will help other thick amateurs like me to setup their machine : )

He Teme! That 5-hole steam tips looks like the one that Reneka ships with it's machines. I like it very much, but I'm quite biased as that's the only one I ever used in the long-term. But it works in the shop and it works at home :)
Hi Lukas!
That is a very sharp observation. The 5-hole tip is indeed a Reneka tip (or a clone manufactured by Ascaso). I agree that it is very nice.
La Marzocco is also sending me their new 3-hole tip, which I am very much looking forward to.

Hi Teme,
Great review. Keep up the update! It's invaluable to many potential GS/3 buyers.
Question... How do you find the intra-shot consistency? I am especially interested in the wake-up shots and its relation w/ subsequent shots (as well as w/ other wake-up shots).
Thanks!
Ben
Teme - you mentioned the GS3 may be less forgiving in distribution/tamp technique than the Andrea: isn't the Andrea vibration pump powered and the GS3 rotary? I've heard similar observations from people who've moved onto rotary pump machine from vibes, even of the same model machine such as the Bricoletta. Sudden ramp up from the rotary versus gradual from the vibe.
Or has this been considered and addressed in the GS3 with pre-infusion?
Hi Ben,
I have not yet had the time to make thorough evaluations on that. It is also difficult to make comparisons to the Andreja, since I have just recently bought my Scace and meter.
I will have to comment on this later.
Br,
Teme
Hi Kareem,
You are right. I think the forgiveness factor is down to the slower pressure rampup of a vibe pump. Having said that, the GS3 has flow restrictors that make the rampup less sudden on the GS3 than on most rotary pump machines.
I look forward to the availability of the paddle group, which would allow for even more control over the pre-infusion...
Br,
Teme
Teme, thanks for the updates on the tips here and on CG. When you say the GS3 has a flow restrictor, do you mean something other than the gicleur?
Hey Teeme,
Now that you have gone dual-boiler, I think that it's time for you to relinquish e61hx.com ;P
Cheers,
Luca
Hi Teme,
no recent news on the GS/3 delivery
yet, we have to remain patient. May I ask you sth.? When was your GS/3 build? Serial 002 was build in 01/07.
Kind Regards,
- Malte
Hi Jeff,
I mean the gicleur. I think it si 0,6mm on the GS3.

Hi Luca,
I have been phasing out the e61hx.com domain for a while now and try and encourage everyone to use the espresso-passione.com url instead. At some stage I will make the e61hx.com an empty page with a link to the new url...
I would also be interested in hearing where the old url still pops up...

Hi Malte,
My GS3 was built on February 1st 2007.
I hear that the next batch of machines is on their way...

Hi Teme,
You want a coffee grinder that is of the same caliber as the GS3.. Have you ever thought of an Eureka coffee grinder from Italy!
Thanks,
Eric
Hi Eric,
If you are referring to the large conical Eureka / Conti Valerio that is also sold with the La Marzocco brand, yes, I did consider it. However, with its glass hopper (which cannot be easily chopped down) it is too tall for me.
Nevertheless, I have made my decision(s) regarding the grinder(s). More on that soon...
Br,
Teme
Can't wait any longer!
I'm wondering if your Casadio and Compak have arrived yet. If so, I would be fascinated to hear your thoughts on them. I am pondering a grinder upgrade and arrived at a very similar choice.
Thanks, Giles.
Hi Giles,
I am afraid that I still have not received the grinders. However, I hear that the Casadio is already in Denmark and it should be delivered tomorrow (Monday the 7th of May).
Unfortunately I will have another busy week with a lot of traveling and I will probably not have much time to play around with the Casadio before next weekend...
Br,
Teme
Teme,
Thanks for being a GS3 pioneer. I just received GS3 three days ago: S/N # 0054. Your early observations with accompanying pictures made my set up of the machine straight forward. I didn't take apart the front of the machine as much as you, but still managed to tighten the expansion valve using soft-jawed pliers. Would it be possible for LM to stamp a hex key slot inside the expansion valve hole? Adjusting the valve would then be a breeze. I have found the immediate feedback from the chronos countdown and the metered-shot flow very helpful, like you.
I have experienced a few minor annoyances. As mentioned by others, in pour-over mode, refill tank message appears even when the tank is full. Positioning of the tank is picky. Switching over to plumbed-in will solve this problem, but I want to be able to take the GS3 with me on some of my travels, so I will have to deal with the pickiness. I understand that a new reservoir with a removable lid that allows cleaning is coming. Maybe it will connect with the sensor-system more consistently. I also have found that when I pour a shot, the rotary pump causes the tray and grill to vibrate, resulting in my shot glass or cup to dance forward. I have placed anti-slide material (used in tool boxes) under the cup and the cup stays in one place now. While set up the machine & running the machine, I found stainless steel fines collected in the group screen and in the cup I was pouring into. I flushed the machine about 20 times before the fines were completely cleared. My machine did not come with a paddle. I assume that this will be a retro-fit sometime in the future. I also tried to register my machine on the LM site yesterday. There is no GS3 on the pull-down menu and the site expects everyone to be a business. I spoke with Mary Diamond of LM and she has notified the webmaster of the problems.
Lastly, and most importantly, I have roasted and brewed five single-origin beans, so far. The aroma and flavor of very one of them have been astonishing. Every day is a new adventure. Thank you, thank you, La Marzocco! Thanks, again, Teme!
Ron
Hi Ron,
Congratulations on your new machine! And thank you for your kind words.
I have not had the vibration issues, at least not to the extent that you appear to be experiencing. I sometimes get a viration that rattles the drip tray cover, but I managed to fix that by applying some electrical tape on the drip tray so as to make the fit of the cover tighter as well as softer.
Also, I have not seen any stainless steel or other undesirable material in my brew water or in the group screen. What I have noticed that the grouphead does appear to collect coffee grounds and oils under the shower screen slightly more than an E61 does. But this does really matter at all since taking the shower sreen off and doing the cleaning is a breeze with the GS3 and this ease of cleaning is one of the things I did miss with my previous machine.
Congrats again,
Teme
Thanks, Teme.
On the grinder front, I have ordered a Versalab M3. Laura of Versalab said my VISA would be charged once the order was received by the machining company. As this has happened, I am assuming that the M3 should be arriving in a few weeks. I will let you know how it compares with my Mazzer-Mini Electronic B.
Cheers,
Ron
Hi Ron,
Congrats on your grinder of choice. I have always been intrigued by the M3. I hope it works out well for you and I would certainly be interested in hearing your experiences...

Hi Folks,
I am enjoying and learning a lot from your blog. I am opening a large restaurant with 100+ seats and want to serve fine coffee and espresso. We estimate less than 50 cups per day, so we are looking at the GS3. Can anyone comment about that use? Also, we are looking at the Versalab packer and grinder. Would these work in a restaurant environment? Will a server with moderate training be able to draw a great cup? are there better ways to go for our purposes?
And what about regular American coffee?
Thanks for any help you can provide,
Chris
Hi Chris,
For a restaurant with a 100+ seats, you expect less than 50 cups per day?
Anyway, I use the GS3 as my home machine. I think it is great for this purpose albeit probably overkill. I think the GS3 is also great as for example a reference machine at a roaster, but for a coffee shop or restaurant I would always go for at least 2-group machine.
With regards to the Versalab grinder and packer, I honestly think that you would not want them in a commercial setting such as yours (because of both capacity as well as potential reliability issues).
Br,
Teme
Hey Teme,
I just received my GS3 and am blown away. I've used a Silvia for many years and had a short departure to the world of a Jura super auto as I was travelling a lot and my wife enjoys convenience.
My machine vibrates enough to cause the cups to shift a bit. It isn't a huge problem but I'll look for a way (like your electrical tape) to deal with it.
My first two day frustration is with the water reservoir sensor. Despite having the new clear reservoir, I have to fight the drip tray placement to get the Fill Reservoir message to stop. One thing I found is that by quickly powering off and on stops the messages quite reliably.
Already, the espresso and cappuccino that I've produced is better than anything done in-house. Milk steaming is going to take me a while and I'm curious about your comments re the different steam heads.
What an amazing machine and I've already doubled my daily caffeine intake.
My serial number is 0091 and has a build date of 06 07 fwiw.
And I just checked that mine came with the 3-hole tip.
Hi there,
If you get a lot of vibration of the drip tray and you are also having trouble with the reservoir sensor, are you sure that the drip tray is properly in place? When new it really can be quite tight...
I am happy to hear that you are pleased with our machine. I certainly appreciate mine even more now than I did when I received it :)
Br,
Teme
It turns out that I needed to pull the two metal flaps at the back of the water reservoir - they were pushed too flat and were not making contact with the sensor, even when the drip tray was properly seated.
I also used your electrical tape trick and now there is no vibration and the GS3 is much more quiet when the shots are pulled.
I'm now trying to learn all of this new equipment - I'm trying to figure out what the right coffee dose is for each of the portafilter baskets. I assume that the smaller ridged one is a double (Mazzer Mini Electronic default measure). Is the larger one a triple or quad?
Thanks for your blog to help me get more comfortable for this remarkable machine!
The machine comes with single and double filter baskets.
Br,
Teme
Thanks. I was confused because I didn't realize the the double-dose from my new Mazzer Mini E was so short by default (at least for the bean I've been using). Too many new variables at once I suppose, and too little experience from the operator ;-)
