La Marzocco GB 5

La Marzocco GB5: Elegant engineering with superior temperature control

The GB5 espresso machine from La Marzocco is a high-end machine that is designed for superior temperature control. It features a number of innovative technologies, including:

  • Saturated groups: The GB5 uses saturated groups, which means that the water never leaves the boiler during the brewing process. This ensures unsurpassed thermal stability, shot after shot.
  • Dual boiler system: The GB5 has a dual boiler system, with separate boilers for espresso brewing and steam production. This allows the barista to optimize the temperature for each process, resulting in better espresso and steamed milk.
  • Dual PID (coffee and steam): The GB5 has two PID controllers, one for the coffee boiler and one for the steam boiler. This allows the barista to electronically control the temperature of each boiler, ensuring precise and consistent results.
  • Insulated boilers: The GB5’s boilers are insulated, which helps to reduce energy consumption and contribute to temperature stability.
  • Ruby flow restrictors: The GB5 has synthetic ruby flow restrictors, which resist scale formation and erosion. This helps to keep the machine clean and in good working order.
  • Pre-heating system: The GB5 has a pre-heating system, which pre-heats the water before it enters the coffee boiler. This increases productivity and helps to ensure that the espresso is extracted evenly.
  • Stainless steel portafilters & precision baskets: The GB5 comes with stainless steel portafilters and precision baskets. These are designed to improve the quality and consistency of the espresso that is produced.
  • Digital display: The GB5 has a digital display that shows the temperature of the coffee and steam boilers, as well as the shot timer. This helps the barista to produce consistent results.
  • Hot water economizer: The GB5 has a hot water economizer, which allows the barista to fine tune the temperature of the hot water spout. This is useful for making drinks such as tea and americanos.
  • Tall cups: The GB5 can accommodate tall cups, up to 2.5cm /1in. in height. This is ideal for coffee shops that serve to-go drinks.
  • Auto back-flush program: The GB5 has an automatic back-flush program. This helps to keep the machine clean and free of scale, which can improve the taste of the espresso.

The GB5 is a high-performance espresso machine that is built to last. It is made with high-quality materials and components, and it is backed by a one-year warranty. If you are looking for an espresso machine that will produce consistently great results, then the GB5 is a great option.

La Marzocco: Pioneers of Temperature Stability and Dual Boiler Innovation

Founded in Florence in 1927 by Giuseppe and Bruno Bambi, La Marzocco has been a longstanding Italian manufacturer of high-end professional espresso coffee machines. Widely recognized as a top-tier brand, La Marzocco has revolutionized the industry with their groundbreaking innovations. 

One of their notable contributions was the introduction of the first espresso machine with a horizontal boiler. This departure from the traditional vertical structure allowed for the efficient organisation of brew groups in a horizontal fashion, providing both baristas and customers with improved interaction opportunities.

However, it was the launch of their dual-boiler GS series in 1970 that solidified La Marzocco’s reputation as an industry leader. This innovation fundamentally transformed the way baristas approached coffee brewing and continues to influence modern practices. By incorporating two separate boilers—one for brewing coffee and the other for steaming milk—the GS series enabled simultaneous operations, eliminating the need to juggle between boiling steam and coffee brewing. 

The introduction of the dual boiler system not only streamlined the brewing process but also addressed the critical issue of temperature stability. Maintaining a consistent temperature during the brewing process is essential for producing high-quality espresso. Fluctuations in temperature can significantly impact the flavour profile of the final product. La Marzocco’s dual boiler system provided baristas with greater control over the temperature, allowing them to fine-tune the flavour characteristics of each cup.

Another significant improvement came with the saturated group head (gruppo saturo) design. By integrating the group head directly into the boiler, La Marzocco’s saturated group ensured exceptional temperature stability and consistency. This advancement in engineering set the stage for modern cafes, where baristas can achieve remarkable precision and control over the brewing process.

The advantages of dual boilers are still highly relevant today. Owning a coffee machine with two separate boilers enables baristas to deliver fresher and more consistent drinks, with minimal delays or concerns about temperature fluctuations. The ability to texture milk while brewing coffee simultaneously provides a practical solution for those seeking efficiency and speed.

In conclusion, La Marzocco’s commitment to temperature stability and dual boiler innovation has redefined the coffee industry. Their machines empower baristas to unlock the full potential of their coffee beans, resulting in exceptional espresso beverages. With a La Marzocco coffee machine, you can experience the perfect harmony of precision, consistency, and flavour, elevating your coffee brewing to new heights.
