The Pearl Model S from Acaia has been designed to be a link between coffee roasters and serious home brewers. Featuring a built-in interactive brewing guide, the Acaia Pearl Model S is an easy way for roasters and home brewers to connect and share their favourite recipes. Using the accompanying Brewguide app., home brewers can transfer recommended recipes onto the Model S scale, and then use the prompts on the scale to brew, without using the app. The Brewguide app. makes sharing recipes super easy - even if other brewers don't have the app or a Model S scale, recipes can be shared via a link or a QR code, which takes them to the recipe on a website.

New Features:

- LED Display: Now shows a dot matrix to support the three different font sizes and an alphanumeric display.
- Capacity: Increased to a 3kg capacity.
- Internal Components: The support structure inside the scale has changed from plastic to metal, creating a more reinforced top and a slightly heavier scale.
- Brightness Levels: There are four different brightness level options; low, medium, high, and bright.


- Brewguide: Using the Brewguide app, you can easily transfer recipes from the app to the Pearl S and browse through verified recipes from roasters. Through the app you can update some settings on the scale, including turning the scale on/off, adjusting modes, units, temperature, and the auto-off timer.
