Baratza Sette 270WI The "i" in 270Wi stands for intelligence - the grinder now quickly calculates and predicts the stop point when you change your grind setting, beans, or dose weight. This eliminates the need to adjust the offset. The new 270Wi maximizes its built-in Acaia high precision scale by filtering unpredicted vibrations that could affect dosing accuracy, such as door closures, footsteps, unsteady surfaces. A "quick burst" feature allows you to add small increments of coffee to your final dose after the grinder has stopped. In the event of a software update, it can be installed wirelessly via the integrated Bluetooth using Apple phone or tablet. Recent versions of the Sette 270W are upward compatible to the Sette 270Wi, by purchasing and installing the new 270Wi Display panel and then updating the software via an Acaia App. GRINDING MECHANISM The Sette Series has, at its core, a revolutionary grinding mechanism that produces game-changing performance. Key aspects of this innovative mechanism include: Straight-thru vertical grinding of the beans (highly efficient and results in minimal residual coffee in the system). Rotation of the outer ring burr (with twice the surface area of the cone burr) along with proprietary tooth geometry, produces grinding thru-put that is two to three times that of others in its class. Proprietary gear box (planetary + crown gear) that maximizes efficiency of torque transfer, resulting in lower power consumption and much less heat. Powerful DC motor for maximum starting torque and efficiency, resulting in cooler operation. BURRS & BREWING METHODS Manufactured by Etzinger in Liechtenstein, the Sette 270Wi is built with 40mm conical AP (all-purpose) burrs, which produce weight-based espresso grind, as well as grinding for manual brewing requiring a finer grind range (e.g.weight-based Aeropress and Hario V60). They grind coffee at 3.5g to 5.5 g/sec. depending on the roast and the setting. The burrs are durable and will remain sharp for many years. The clever design of the Sette Series burr assembly offers you, the user, the ability to exchange the cone burr in less than a minute with no tools and no recalibration.

CONVERTIBLE DEVICE HOLDER & GROUNDS BIN A built-in convertible holder, unique to the Sette Series, allows you to grind directly into your portafilter, the supplied grounds bin, or most of the popular brewing devices (V60, Clever, Kalita, etc.). The rubber sleeves on the arms are fully rotational allowing you the option to position them in a way that best suits the tool/brew-method you are using. The arms can accommodate portafilters from sizes 49mm to 58mm and the holder includes an integrated hook for stability. The Sette’s grounds bin is made from an anti-static plastic, with a molded spout for easy pouring into your preferred brewing device. It has a usable capacity of 160g (Med Roast). ACAIA - (WEIGHT-BASED DOSING) This grinder was designed with a built-in scale using the weighing technology of Acaia, giving precise and accurate weight-based dosing, and a 10th of a gram sensitivity. The 270Wi has the revolutionary ability to grind by weight directly into a portafilter - a breakthrough in grinding technology! This unique grinder design responds to the Specialty Coffee user trend of using specific weight based recipes for coffee preparation. HOPPER The hopper holds approximately 300-400g of coffee. An innovative bean shutoff feature in the collar permits no-mess, no-fuss hopper removal for changing out beans. DIGITAL CONTROL PANEL A user-friendly front mounted control panel has an easy to read backlit LED display. Three programmable buttons allow for grind weight setting within 0.1 gram. Simply press the start button and the Sette automatically delivers precise dosing. GRIND ADJUSTMENT The Sette has a macro adjust of 30 steps, grinding from espresso to manual brew. A step-less micro adjust with 9 in
