Overview

La Marzocco's GS3 Espresso Machine is designed for the passionate espresso enthusiast who knows the only way to be satisfied is to invest in one of the best machines available. The GS3 is pricey, but its commercial-grade features more than balance the cost: Dual stainless steel boilers, powerful steaming functionality, PID temperature control, volumetric pump and variable hot water temperature regulation to name a few.

Features and Functionality

  • Dual Stainless Steel Boilers - A 3.5 liter steam boiler produces strong, dry and sustained steam, easily producing latte microfoam. This is complemented by the separate 1.5 liter brew boiler, which allows for excellent temperature consistency and regulation for both operations.
  • Large Internal Reservoir - 3.5 liter reservoir loads from the bottom, resting behind the drip tray, and features an opening for easy refill without removing the entire unit.
  • Convertible Water Source - Use the internal reservoir or set the machine up to directly connect to your location's plumbing.
  • Sophisticated PID Control - Tailoring your brew temperature to achieve the best extract is simple with this digital-displayed PID that utilizes multifunction keypads.
  • No Burn Wands - Double wall insulated stainless steel hot water and steam wands offer easier handling and cleaning.
  • Internal Volumetric Pump - Also known as a rotary vane pump, this quieter pump is designed to maintain a specific volume capacity that is consistently maintained.
  • Saturated Brew Group - Water is distributed evenly across the brew group, resulting in an more consistent pre-infusion and extraction rate, reducing the possibility of channeling.
  • Hot Water Tweaking - Easily select how much cold water you want incorporated into the hot water pulled from the boiler, tailoring your teas or Americanos to your preferred temperature.
  • Monster Drip Tray - If you don't setup the draining kit, no worries -- the huge capacity of the GS/3's drip tray means you won't have to empty it very often.
Pros
  • Temperature Control - With the PID interface, you can select your ideal brewing temperature based on the coffee you're using.
  • Steam Power - The GS/3 makes tons of dry steam that quickly and easily creates silky microfoam.
  • Build Quality - The commercial-grade build quality makes this machine a must for your home or cafe.
Cons
  • Price - This is one of the most expensive machines that's designed for home espresso. A good workman never blames his tools. You won't regret it :)
  • Size - The GS/3's large size takes up prime countertop real estate. If you've got it, flaunt it! Park that baby front and center.
  • Aesthetics - The GS/3 is much more utilitarian in its design and style and is not quite as sexy as some of the other machines that are available on the market.
How Does it Compare? 2017 Update! La Marzocco has made some recent changes to the GS/3 MP version. The new GS/3 MP sports a redesigned conical valve (a common repair point in earlier models), a new brew pressure manometer at the brew head, and a modified pump switch that allows for pre-infusion and manual pressure control when using the reservoir. Both AV and MP configurations now feature a new cool touch steam wand that replaces the teflon inner lining with a double wall stainless steel design.

What is the quality of the new black and white finish options for this machine? Are these coatings that are scratch and chip resistant, or is the stainless still a more durable option?

Best Answer: Both machines allow a great deal of adjustment to get exactly the kind of espresso you want, so I think a competent barista could easily dial in both machines to produce identical espresso. The important question then is which machine is more consistent, and I have to say I've been very happy with the consistency of my Linea Mini. Another question is how many shots each machine can handle in a given period of time, but that's only important if you're serving lots of customers (which I am not).

What it is the difference between the automatic and manual models? Which do you recommend?jb
Jay B on Feb 3, 2015
Best Answer: I bought the automatic for home use. I was worried about paddle repairs, and the less than ideal preinfusion with the paddle if not plumbed, and liked the idea of having that automatic cleaning feature. After a year with the machine, these are my thoughts: 1) being able to set a preinfusion has the appearance of speeding things up in the morning... though I don't know how true that is. 2) I like having the automatic cleaning run. 3) I probably should have bought the paddle. I think I would enjoy it more... and in some ways it would be easier, since, other than the preinfusion, I hit the button to shut it off... hence using it like a paddle, but a little more awkwardly... since I squeeze my hand between the group and the hot water tap to reach the shut off button... and have to look at what I'm doing to hit the right button. Yeah, having the paddle would be easier, and more fun. 4) As for the preinfusion not being as ideal if using the reservoir with the paddle (not plumbed), I read the new ones have improved this aspect. As mentioned, it's a personal decision. But if I had to do it over again, I would buy the MP for my style of use.

Enough durability for catering use? I cater out to businesses and parties and would be pulling anywhere from 35-70 shots a gig, working three-four times a week.
A shopper on Mar 11, 2013
Best Answer: I bought the GS/3 strictly for home use. I wanted a professional/commercial level machine because I got tired of pulling multiple shots with long breaks in between to allow the machine to "catch up." I also wanted a straight forward machine with limited automaticity, i.e. less to go wrong or break. Kapow! The GS/3.

From the research and reviews I did before the purchase, this is every bit as durable as the larger machines La Marzocco makes. I would have no fears about quality... 110% here. Pulling 70 shots will take some time, only because it is a single group machine, but with double boilers it will keep up. The limiting factor will be how quickly you clean your filter, refill and tamp. If you have other catering duties, you may fall behind compared to using a multi-group machine. If you have a barista helping you out, this shouldn't be TOO big a problem though.

One of the nicest features IMHO is the auto-on programmability. I have it set to come on every morning for a couple of hours. That way it is hot everyday. If I want to pull a shot, great, it's ready to roll. If not, it goes back to bed. If I want coffee a couple of hours after it falls asleep, I manually wake it up and it's usually still warm enough to be ready in 15 minutes. I don't know if this would be a factor for catering, but I really enjoy it.

I have not experimented with the PID, but you can change the brewing temperature manually to adjust for your different bean profiles. I don't know how much you would be changing beans, but this is a great feature for the perfectionist.

Bottom line, I think this machine really will handle anything the larger ones can handle aside group numbers. Plus, you can throw it in the trunk and take it with you on your next outing! I love mine.

If you select the manual version, can you alternate between using manual and auto? (In other words, if I purchase the manual version so that I can experiment and control the water manually, is there a way to switch it over to "auto" mode for when volume consistency is needed with pulling a lot of shots at once?)
DaveB on Jan 28, 2016
Best Answer: I have the manual version, and the auto buttons do nothing at all. In fact it adds to the confusion of the menus considerably as most of the buttons are useless. Fortunately the only time I need to navigate the menus is to change the boiler temp or the wake/sleep time, both of which I do rarely so it's manageable.
I still prefer the manual version because I shoot for consistent shot weight in and out, and don't want to constantly adjust the grinder throughout the day for consistent time. It's easier to just wait until desired output weight (or volume if I'm lazy) is hit and stop the pour manually. I note the shot time on the clock when done and only adjust grind if way off.

I have a "ECM Technika Profi IV" and am considering to replace it with the "La Marzocco GS3".
Is this recommendable?
Bruce O on Dec 6, 2016
Best Answer: That's about the biggest jump in quality you can get as far as home machines go! Your ECM is a simple, elegant heat exchange design, while the GS/3 is a full-fledged saturated group double boiler machine.

Depending on your usage and the model of GS/3 you're interested in, you'll likely see improved heat stability and workflow (with the automatic version). If you're looking to get more control over your shot extraction, the MP (manual paddle) version gives you manual control over pre-infusion.

It is worth noting that the GS3 will be nearly 2x the width of your ECM. If space is an issue, I'd recommend something like the Rocket R58, which will be a very similar design as your ECM but with a double boiler layout instead of a heat exchanger.

I know perhaps no one would really be able to answer this dumb question but still, I'm looking for a good home use commercial espresso machine and have just returned a Jura Micro 1 (automatic, I know). Will this $7,000 baby last my whole life (40 years)? Thanks in advance.
amanda on Feb 26, 2015
Best Answer: While we certainly can't estimate that it will, it is a very sturdy and reliable machine. I haven't heard of anyone getting quite that many years out of a machine like that, but I think comfortably, if you're properly maintaining the machine including descaling and backflushing regularly, you could see 10-15 years from it.

To fully utilize the Pre-infusion does the machine have to be plumbed?
A shopper on Jul 2, 2013
Best Answer: No, you can move the paddle of the La Marzocco GS/3 to the middle position in order to allow water to flow from the brewhead for your pre-infusion even when the machine is not plumbed into your house water supply, and instead using the tank.

Using reverse osmosis water, I would like to know how the GS/3 deals with low water signal from the tank ? The Rocket R58 does not perform well with this type of water.

Had this machine for three years and now is sputtering. Only pulled about 2 shots per day. Now I cannot get it fixed. La Marzocco does not provide service. There are no techs willing to make house calls. Techs only service commercial establishments. Called La Marzocco tech support but they could not help. Also they recommended that the machine be serviced once a year by a professional. (Posted on 5/2/2017)

Very expensive, high quality and extremely consistent performer. We made the decision to purchase this machine due to the excellent espresso quality it produces even by a novice barista using all the tools provided by the PID. Justification to spend this much came down to an expected long life time of enjoyment. After several weeks of morning lattes and occasional espressos the time saving features and ready to use nature of this machine really stand out and add to our daily pleasure.

The powerful steam means I can steam milk and be finished before the shot is done, of course this makes for a small window to get it just right for latte art, however even during the learning process the results were never far off. (Posted on 4/28/2014)
La Marzocco GS3 MP thoughts after a few weeksReview by mac12563
Price
Quality
Value
The GS3 is solidly built and control of the variables on the machine make tweaking your shot a breeze. The controls are well thought out and easily accessible. I think the toggle switch for the steam works much better than a screw valve or having a lever control on the far left of the machine.

The machine is designed very well for placement in the average kitchen. Fitting under cabinets without issue. Overall the machine is designed to fit well in a home environment without sacrificing the technology to make a fantastic coffee.

I upgraded from an Isomac Millennium which was a great machine, and I have made many memorable coffees with it. The GS3 gives me more flexibility and ease to dial in and replicate consistent shots every time. I roast my own coffee so slight differences in the roast are not an issue because of the ease of adjustments on the GS3.

The GS3 is a tool to make fantastic coffee so knowing the tool is everything. Expectations that buying this machine alone will produce great coffee is foolish. The GS3 though makes getting there easy and simple.

I am extremely happy with the GS3 and though expensive the build and quality justify the price. I am able to produce coffee that meets and many times exceeds coffee produced on commercial machines. I recently had a coffee at Intelligentsia and though the shot was very good and pulled on a Synesso Cyncra, it was not as good as I have been able to produce at home. This illustrates that the human variable is the key to great coffee and having a great machine is not enough, but having a great machine can simplify the process without question.

Pros: Good ergonomics, exceeds design requirements for home user, great technology, great fit and finish, great brewing characteristics.

Cons: N/A (Posted on 10/2/2012)
LM GS/3 Paddle after 3 weeksReview by Marshal
Price
Quality

Make sure that you buy the double, Strada portafilter basket, and the LM bottomless portafilter. You'll be glad that you did.
Why? The standard LM basket is ridged near the top. That prevents proper tamping unless the basket is filled with 19 or more grams of grounds. The Strada is smooth-sided. The holes are also more uniform in size. That seems to provide a better tasting extraction. The bottomless portafilter seems to provide a better coffee taste. That may or may not be the case. What it definitely does do is allow one to see the coffee extraction. Water channeling and water spraying, which indicate an uneven tamp, are obvious by looking at the bottom of the basket during extraction. So is the coffee's delightful tiger-striped coffee vortex for which LM coffee is noted.

Pros:
Great Taste, Easy To Use, Commercial Grade, Quick Brewing, Easy To Clean, Quiet, Large Water Container

Cons:

* How you use the product -- to prepare espresso; hot chocolate; tea. All good!
* Things that are great about it -- quick to heat; two boilers means no waiting. Froth milk or brew coffee when you wish; turns itself on/off; adjustable in more ways than I know.
* Things that aren't so great about it -- flawed portafilter basket design. There is a ridge that blocks proper tamping when using less than 19 grams of coffee grounds in the double basket. As a result, your espresso grind will be all over the map in attempts to correct what turns out to be a tamp issue. Buy an LM ridgeless basket and chuck the stock unit.

SpecialtyReview by Eric

The GS3 is amazing with lots of coffees, but this is truly a machine designed for specialty coffee. I've worked with commerical La Marzoccos, Synessos, and Simonellis, and this little GS3 delivers nearly identical exceptional quality. At home, I use a Rocket from Seattle Coffee Gear. But I also do training and consulting for a small Espresso Bar in New Orleans that uses the La Marzocco GS3, and this machine is simply amazing in quality and consistency. EVERYTHING is commercial grade yet designed for a smaller setting.

The built-in PID allows for precise temperature control and experimentation (if you are adventurous and like single origin espresso, especially). Manual pre-infusion (which locks in fines and results in a more even extraction) is possible due to the mechanical paddle. Also, the interface shows you the time of your shots in seconds (no need to scramble for your timer). The shots are GORGEOUS when dialed in correctly. Tiger striping is easily visible and this portafilter is one of the few pro-sumer types where the espresso rolls out of the spouts in a more inward direction, falling perfectly into your demi (this is something usually only seen with large, commercial machines).

The water reservoir and drip tray are very large. The double boiler allows one to easily brew and steam simultaneously, and the steam wand is capable of commercial grade micro-foam for latte art.

Finally, the portafilter and double basket that La Marzocco issues (either VST or regular basket) are professional grade and easily allow for the type of up-dosing that is commonly used in specialty cafes today (18-21 grams). This is rare among other pro-sumer machines with smaller baskets (unless you go bottomless and switch to a larger basket). Simply put, if you want your shot to taste the way it does in your favorite specialty cafe, this is one of the only machines that will get you there consistently. Seems pricey, but offers so much more than any other machine can in its class.

Pros:
Easy To Use, Commercial Grade, Quick Brewing, Easy To Clean, Great Taste, Large Water Container

Cons:
