A Sharper, Bolder GB5
The GB5 from La Marzocco cut unique curves into the corners of the straight-forward Linea shell, bringing it into the 21st century under a new name. That was over 15 years ago (2005), though, and style changes, as did the Linea itself with the introduction of the PB line. La Marzocco created the GB5 S to effectively modernize its former nod to Giovanna Bambi, replacing Donatello’s Marzocco lion on the corners with Florence’s fleur de lis, sharpening the lines, and bringing the internals up to date with the cutting-edge Luminaire electronics found on the Linea PB, Strada, and KB90. The S is also bolder than its predecessor, with red accents on the buttons and branding. As with any La Marzocco machine, the materials are premium, including the AISI 316L stainless steel boilers, which, more than other substances, prevent heavy metals from being dissolved into the water.
Classic Meets Contemporary
As expected on a La Marzocco machine, the GB5 S is outfitted with temperature-stabilizing features, such as saturated groups, dual PIDs, re-engineered (more efficient) water pathways, and ruby flow restrictors that resist scale. Some of La Marzocco’s very recent innovations are included, too, such as easy-rebuild steam valves, accessible in seconds, on the vacuum-insulated, double-walled steam wands; easy-access flow restrictors on the brew solenoid; an automatic backflush program; and, on the AV and ABR models, dimmable LED barista lights. The GB5 S provides the barista control over boiler temperature, brewing volume, hot water tap dose, automatic cleaning cycles and more, and, because it is a connected machine, the parameters can be adjusted in the app.
GB5 S AV and AV with ABR
This model, the AV, or auto volumetric, is on the automatic end of the control spectrum. The barista can program up to four shot volumes per grouphead in addition to having the option of a continuous run, or manual shot. With the Auto Brew Ratio, an option on the AV model, the barista can program shots by weight and rely on scales in the drip tray, which are wired into the machine’s electronics. The interface above the groups includes a display that shows all the vitals from the boiler temperatures to shot duration and two manometers, one for the brew boiler and one for steam boiler, to show pressure in real time. The two steam wands, one on either side, are turned on and off by a dial, similar to the Linea, PB, and original GB5. All in all, the S proves a complete overhaul of the software and hardware found on the 2005 model.

Best Alternative Milks for Barista Quality Espresso Drinks
Alt milks are all the rage. Or rather they were all the rage and now they are just a rage, the status quo. In a good way. What first started as a way to accommodate dairy enthusiasts with a lactose allergy, and mainly just with a sugary soy bean beverage that has since fallen out of favor, has escalated into an industry, albeit a small one.
What We Are Brewing: Parlor Coffee
Not surprisingly, the office at Prima is always stocked with coffee. Always. Since we sell coffee equipment, and only that with which we have been able to make consistently tasty cups, we find it necessary to sample coffees from all over the country, at times the world, and, although we prefer lighter roasts, from all over the color spectrum.
Prima's Coffee Gear Preview 2021
2021 is shaping up necessarily to look a lot like 2020. More time at home. More time for contemplation. More stress brought on by screens and moments like this: “You’re on mute.” “Oh.”
