Less Stress
Smart workflow and ergonomics are the name of the game for the KB90. When a barista is busy pulling shots
and steaming milk hundreds of times per day, the repetitive motions of the job can be taxing on their body
(just look up “barista wrist” and you’ll see what we mean!). That’s where things like the new straight-in
portafilter come in: it’s designed lock in and pull a shot using a more natural and less stressful movement,
eliminating awkward twisting motions and offering a much gentler experience for the barista’s joints. The
portafilter slides into place on rails and locks upward with ease, and removing it post-shot is done with a
press of the thumb on a release tab. This makes for a slightly more complicated group, but relieves a great
deal of stress on the barista’s body.

New Features
The KB90 also comes complete with a suite of new features, including the brand new Pro Touch wands. Unlike
other cool touch steam wands on the market, La Marzocco’s are made of dual wall vacuum insulated steel, which
seal in the heat and keep the wand cool to the touch even after the busiest of lunch rushes. New steam valves
are not only also easier on barista wrists – with a smaller turning radius to engage full steam power – they
are designed to be rebuilt more quickly and easily, allowing a tech to shut off steam at the boiler so they can
swap out o-rings and rebuild the valve without having to shut the machine down entirely.

Auto Brew Ratio
With optional drip tray scales, the KB90 is able to pull shots with Auto Brew Ratio mode. ABR allows the
barista to weigh a dose in the portafilter directly on the shot scale, and the machine will pull a perfect shot
to your desired output ratio. ABR machines can also be run in Mass Mode, so you can instead pull shots to your
desired output weight directly into your cups. And with Drip Prediction, the KB90 is able to predict when to
cut the flow to the shot to make sure your beverages are consistently tasting their best.

Anatomy of Espresso Drinks: A How-To Guide and History of Espresso Drinks
Whether you’re actually sitting at a picturesque Italian cafe or simply visiting your local coffee shop,
espresso does an extraordinary job at blending science and history to form a coffee delicacy capable of
sparking a new found appreciation for the technique and art that goes into coffee, or even at times, if only
for a moment, takes you to the distant land of its origins.

Espresso Machine Maintenance
You and your machine make great espresso; let’s keep it that way. Taking care of your espresso equipment
will ensure that it lives a long life and always does what it should. Here’s your chore list.

Product Maintenance | Gasket Replacement
When it comes to giving your espresso machine a long and happy life on your bar, preventative maintenance is
crucial. Regularly replacing worn out group head gaskets is an important part of that maintenance, since the
gasket creates a tight seal for your portafilter.
