Today, espresso is almost synonymous with petty bourgeoisie, a symbol of white-collar status, but looking back on history, it is not difficult to find that espresso is actually a proletarian drink with strong roots. Its taste is rich and can satisfy the needs of people's taste buds in the shortest time. With the introduction of a large number of coffee machines into the market, the rapid and stable production of espresso, and the fact that practitioners can be employed after a short period of training, these conditions have made the road to commercialization of espresso smooth. On the road to coffee industrialization, La Marzocco has played a major role.
 
La Marzocco produced the world's first horizontal boiler coffee machine, allowing baristas and customers to better communicate face-to-face without having to be separated by a vertical boiler. But the biggest influence on La Marzocco, and also on the development of espresso, was the launch of the double-boiler coffee machine GS in 1970, a series of machines that have been iterated to this day. The advent of dual-boiler coffee machines further improved the efficiency and stability of espresso, laying the foundation for its commercialization, and Starbucks used all commercial semi-automatic coffee machines from La Marzocco in the early days.
 
The basis of espresso is espresso. If the pressure is not enough, the water temperature is too low, the coffee beans are not fully extracted, and the taste of the coffee will be more sour. If the pressure is too high or the temperature is too high, the coffee will be very bitter, and if there is severe overbrewing, there will be some harmful substances in the coffee.
 
Baristas usually think that the ideal extraction pressure for espresso is 9 Bar and the ideal extraction temperature is around 90°C, which will be slightly adjusted depending on the roast depth of the coffee beans and the thickness of the coffee grounds. The closer the pressure and water temperature stability values are to the above values, the better the performance of the machine.
 
In response to these questions, La Marzocco's home semi-automatic coffee machine delivered a high score. Whether it's the GS series or the Linea mini, with a rotary pressure pump and twin boiler designs, and each boiler with PID temperature control technology, the performance of a commercial coffee machine is the perfect choice for coffee lovers in terms of design, performance and sentiment.
 
Rotary pressure pumps are standard on commercial machines and are a rarity in home coffee machines. On the one hand, because it is much more expensive than vibrating pressure pumps, and on the other hand, it is also quite larger than vibrating pressure pumps.
 
In terms of performance, rotary pressure pumps have an absolute advantage. The pressurization principle of the vibrating pressure pump is similar to that of the pump, and the extraction pressure is increased from the normal pressure, so the machines using the vibrating pressure pump are marked with the extraction pressure as 15Bar or even 19Bar, and the values here refer to the highest pressure, trying to use the high pressure at the end of the extraction to make up for the lack of extraction in the early stage. The rotary pressure pump, on the other hand, maintains the ideal pressure at all times.
 
The GS series has the best reputation in the line of home coffee machines, with each generation of product design language consistent with the original GS, and the wider body is well compatible with rotary pressure pumps and two independent boilers. The 1.5L extraction water boiler ensures the continuous cup dispensing capacity of the GS series products, and the water temperature will not drop sharply due to the continuous dispensing, even for stores that do not focus on coffee, GS3 can fully cope with it. In comparison, the Linea Mini's 0.17L extraction boiler is small, making it difficult to cope with a gathering of friends.
 
In terms of design, GS is contrary to the norm of most high-end semi-automatic coffee machines, not directly exposing the stainless steel, but covering it with a matte black coating, and decorating the sides with well-textured wooden boards, the wood texture makes the style of the whole coffee machine rise a lot, giving people a retro and calm feeling. The Linea Mini, on the other hand, is more conventional, with a stainless steel exterior but is available in a variety of colourways.
 
La Marzocco's main business has always been business machines, and there is no e-commerce platform purchase channel in China for the time being. La Marzocco machines are available for sale in some specialty coffee machine stores, and can also be ordered through the official website. The GS3 has a reference price of $7,100, while the Linea Mini has a reference price of $4,900.
 
From the date of purchase, the official provides a 13-month warranty, but normal wear and tear parts such as gaskets and filters are not covered by the warranty. At the same time, if the damage is caused by limescale, it is not covered by the warranty. Therefore, it is best to use purified water, and if you are in a region of northern China where the water quality is harder, then it is important to have a water purifier.
