About the Pearl S

Pearl Model S Versions

This article is for the original Pearl Model S, you can find the 2022 version here.


The original Pearl Model S is designed for serious home brewers and the roasters who want to connect with them.

The Model S features a built-in interactive brewing guide. With its accompanying Brewguide app, roasters can input recommended recipes and home brewers can transfer them into the scale. From there, all you need to do is follow the prompts on the scale, no app necessary.

The Pearl Model S has many different built-in modes, and depending on which you prefer, you can customize your scales by including the ones you wish to use. 

Is the Pearl Model S Waterproof?

The Pearl Model S is not waterproof or water-resistant, the same as the Acaia Pearl. While a small amount of water that is spilled on top will deflect, we do not recommend exposing it to any liquid.

Can I use the scale without the Brewguide App?

Yes, you can. Although you will not have access to the amount of customization or be able to upload any brew guide recipe to the scale’s internal firmware without the app.
