Acaia Pearl S with AeroPress

Built For Everyone

Acaia's newest addition to their scale lineup boasts a solid set of new features, as well as new internal hardware - including a brighter dot matrix display and a longer-lasting battery with up to 40 hours of operating life. Core to the new Pearl S experience are Brewguides, recipes which can be loaded onto the scale using the companion app that brew along with you step-by-step. Recipes can be crafted by anyone with the app, including roasters, pro baristas, and home enthusiasts, so making and sharing your best recipes couldn't be easier. Each recipe can include steps that work directly with the scale, including weighing grinds and pours, waiting for a bloom to finish, and allowing for a quick stir of the slurry.

Flow Rate Indicator

Options For Every Application

By default, the scale includes the following modes enabled:

  • Weight mode: Displays the weight in grams.
  • Timer mode: Displays the weight in grams and a timer up to 9:59.
  • Portafilter mode: Auto-tares the weight of a portafilter, then displays grams when the portafilter is returned to the scale.
  • Espresso mode: Auto-tares the weight of a cup placed on the scale, then auto-starts a timer when the flow of espresso into the cup is detected. Stops the timer and displays the final weight when the cup is removed.
  • Flow rate mode: Displays a timer, weight in grams, and flow rate in grams/second.
  • Flow rate practice mode: Displays flow rate in grams/second and a visual graph that represents the flow rate displayed.
  • Brewguide mode: Hold the T button for one second at any time to begin brewing with the most recent store brew recipe. Double tap the Power button to exit.

The Brewguide App

Acaia's Brewguide app is designed as a companion to the Pearl S brewing scale. Available on both iOS and Android mobile devices, it connects to your Pearl S scale via Bluetooth to manage your favorite brewing recipes and customize your scale experience. From the app, you can search, create, and share brew recipes, as well as send the recipe directly to your scale to brew step-by-step. You can also customize your scale features, by enabling or disabling brewing modes, setting the screen brightness and auto-off timer, setting your desired display units, and even creating your own welcome message for when the scale is turned on.
