This grinder was created using Acaia's weighing technology, which allows for precise and accurate weight-based dosing, as well as the groundbreaking ability to grind by weight directly into a portafilter, which is a first for the home espresso fan! The 270W also has Bluetooth capability for monitoring, logging, and tracking grind sessions, weights, and settings. A tool designed exclusively for the Sette and intended for use by espresso enthusiasts, coffee shops, and baristas. The Sette offers a macro/micro grind size adjustment as well as three preset dosage settings. These qualities when combined provide the user with exceptional repeatability. A built-in convertible holder allows you to grind directly into your portafilter, the provided grounds bin, or most common brewing devices (Hario, Clever, Able Kone, AeroPress) — a feature that sets it apart from other home grinders. The "i" in 270Wi indicates intelligence; when you alter your grind setting, beans, or dose weight, the grinder now calculates and anticipates the stop point promptly. It is no longer necessary to alter the offset.
