Founded in 2013 in the USA, Acaia is the company that manufactures the Acaia Pearl coffee scale. They launched their scale a year after going into business, and it won 2014’s Best New Product Award at the SCAA Expo.

Acaia’s slogan is really badass: OUR WEIGH TO BREW—isn’t that cool?

Acaia was founded with a mission to combine design and technology in the specialty coffee industry.

They are making really good scales for the specialty coffee industry and are one of the best from my experience.

If you visit ten coffee shops, you will find an Acaia scale in nine of them—even here in Romania. And that says a lot about their professionalism and quality.

So, Acaia Pearl is a professional-grade scale—but what makes it that professional?

Well, Acaia Pearl is a professional scale but what makes it that professional? I will talk about my experience as a barista with Acaia Pearl.

The first thing that comes to my mind is that it is very, very precise—like even with 0,0 precise.

When I am working with recipes, the Pearl’s precision helps me get a better consistency. This is really important for developing and perfecting recipes.

The second thing is its durability. We’ve all held our breath when accidentally dropping an expensive piece of equipment like the Pearl. Obviously, it’s better to try to avoid those types of accidents. But this scale is very durable and resistant to shocks.

When it comes to working with a scale as a barista, you need to be careful with the water or the espresso coming from the group.

I have damaged many scales because they got soaked in water, or water was underneath and it goes into the scale.

But with Acaia Pearl, you don’t have to worry because it is water resistant. The scale does a great job, many times the water was underneath the Acaia pearl or it was dripping on the scale and it worked with no problems.

What I love the most about Acaia are the modes that it has. Acaia’s modes help you with espresso extraction and even with coffee brewing, but we will talk later in this article about the modes.
