La Marzocco GS3 Review

For starters, you should know that the La Marzocco GS3 coffee maker comes in two models; an MP (manual paddle) model and an AV (auto volumetric) model.  These two models differ from one another in the presence of a flow-rate profiling feature.  One thing that they both have in common, though, is that while they are very suitable for use at home, they are also designed to meet the specifications and to withstand the rigors of commercial use.

For one, we should probably state that people who do not believe they would be able to devote much time to their coffee-making should leave this coffee maker out of their plans. This is because the coffee maker is both expensive and hands-on.

Overall performance and functions

La Marzocco GS3 - Does It Really Work as Well as Baristas Say It Does?

In terms of how they function, the two available models of the GS3 could be classified differently. The absence of the flow rate profiling feature in the AV model means it doesn’t possess as much manual control, but it is a fully automatic machine.

The extraction and pre-infusion programs that would have been affected by the absent feature are thus subject to programs that come with the machine. These programs could be utilized as the user sees fit.

On the other hand, the MP model that has flow rate profiling is not fully automatic as a result. Baristas who like to tinker with their recipe might find this a very refreshing feature.

Size and weight

When it comes to size, the GS3 is not the most compact coffee maker available regarding its width, and it takes up quite a bit of counter space, but the stylishness means it doesn’t look out of place. The MP model particularly might not be suitable to slide under cupboards as it’s three inches taller than the AV model. The weight of the machine also doesn’t favor constant movement and transportation. At a relatively heavy 73 lbs., you would most likely be better served to leave this coffee maker in its corner of the kitchen.

Material

The La Marzocco is quite expensive if only the price is being considered, but besides the other features it boasts of, the machine is also built to last. The GS3 leverages the use of commercial-grade components to meet up to its use in a commercial setting, and as a result, its longevity in home settings is quite special.

The coffee maker is made from stainless steel, but this can be customized to suit the style of your kitchen via the addition of woody accents to the sides or a change of color to the sides. Beyond the exterior, the boilers within are also made from stainless steel as well.

Boiler

The GS3 is a dual boiler espresso machine, and it possesses a designated boiler for its brewing and another for its milk steaming. These boilers are made of stainless steel, as expected, and they utilize a PID to control their temperatures. It should be noted that the brew boiler has a 50-ounce capacity while the steam boiler has a 118-ounce capacity.

The steam boiler of the GS3 is recognized among home brewers for the impressive amount of pressure it is capable of producing, and the PID mentioned above helps to ensure the consistency in temperature of the boilers while they are in use.

Reservoir capacity

La Marzocco GS3 - Does It Really Work as Well as Baristas Say It Does?

The brewing capacity of many coffee machines is an extension of the reservoir capacity, and the GS3 is not much different. The reservoir of this machine has a capacity of about 3.5 liters, but it isn’t a necessity to use this. Instead, the reservoir can be disconnected, and the machine could be connected directly to the plumbing.

Portafilter basket

In line with convenience and variety of options, the GS3 comes with five portafilters to better serve the needs of users. As such, you can pull espresso shots of both double and single shots as you may wish or utilize the naked portafilter for the dual satisfaction of a richer crema Trusted Source The Complex Science and Indelible Style of Crema - Fresh Cup Magazine Notoriously difficult to perfect, espresso is a drink that invokes strong opinions. There are those who tout crema for its powerful aroma and body, labeling it a major player in the espresso experience. But more baristas are disputing the accuracy of the notion that crema is an indicator of quality. Still others disregard crema entirely, choosing instead to remove it prior to serving. Crema’s role is controversial, yet indivisible from espresso’s legacy and flavor. As Ken Nye—owner of Ninth Street Espresso in New York—puts it, “It’s a very potent little thing.” www.freshcup.com and watching your espresso stream into your cup.

Maintenance

Only comes to cleaning and maintenance digest three doesn’t require more activity than your regular espresso machine. However, you should note that the flow profiling capacity of the machine increases the likelihood of spills, and attention should be paid to the drip tray because of this.

The side panels of this coffee maker should be removed regularly to allow access to and clean the interior. Regular cleaning and maintenance in this way lend even more longevity to the machine, ensuring that your investment in this coffee maker is a long-term rather than a short-term one.

If the machine develops a fault, the manufacturers have made it so that spare parts are readily available and the design is so popular that expertise could be acquired for repairs easily.

Durability and warranty

The construction of the La Marzocco GS3 is a very durable one, thanks to its stainless steel exterior. The fact that they are designed for use in commercial settings also lends more to their durability when used as a home machine.

Durability, however, doesn’t end with exterior construction, and the manufacturers of this coffee maker took that into consideration by ensuring that the working parts are capable of taking on whatever stress they might be subjected to.

For starters, the machine can work at both half power and full power. While the latter helps to conserve energy, the former ensures the GS3 can keep up with the back-to-back demands of consecutive cycles that may be required in cafes. A 13-month warranty policy further supports the durability of this machine.

Price tag

You would rarely see a machine with all of the functionality possessed by the GS3 that isn’t quoted some eye-bulging figure. It should be noted, though, that in this case, the machine is more than worth the price.

The La Marzocco GS3 has the durability, versatility, and quality to justify its price, but it might not be suitable or valuable to coffee-making beginners. As such, despite boasting very good value for cost, the machine can only really be appreciated by those experienced enough to utilize it to the maximum.

Key features

The fact that the La Marzocco GS3 is designated as capable of meeting the needs of both home use and commercial should indicate just how special this machine is. However, you don’t get this type of special service without special high-end features to support it, and the manufacturers of the GS3 went all out in this regard. Some of the key features of this coffee maker are

  • Flow-rate profiling
  • A performance touch steam wand for steaming and frothing of milk
Pros Cons
It is available as both a fully automatic model and a partially manual model It is quite expensive
