Rave Coffee – Brazilian AI learns to sort coffee beans


Cirencester, Oct. 26, 2022 (GLOBE NEWSWIRE) — Artificial intelligence is becoming more and more prevalent in our daily lives. From the automated algorithms that control our social media feeds to the cars that surround us on the road, AI is infiltrating every aspect of modern life.

Recently, Brazilian researchers tested the use of artificial intelligence to sort coffee beans. Using MSI (multispectral imaging) and machine learning, the Brazilian team classifies coffee beans as standard or specialty, depending on what they score on the Specialty Coffee Association’s 100-point scale.

How is specialty coffee sorted?

“Normally, trained coffee tasters will use SCA standards to manually grade and sort coffee. However, it is a time-consuming task,” says Rob Hodge, manager of Rave Coffee. “While the idea of ​​using AI to sort specialty coffee beans is fantastic, it is important that the quality of these beans does not diminish.

Typically, tasters in Brazil and elsewhere will be trained to identify a specialty bean and a standard bean based on a range of different measurements. However, manual testing requires inspecting, roasting, and tasting coffee samples, which can be an extremely time-consuming process.

Whether AI can be used to sort out specialists green coffee beans from standard coffee beans, this would not only speed up the sorting process, but also ensure that the quality of all organic green coffee is consistent.

How does the AI ​​inspect and rate green coffee beans?

As part of the study, four different machine learning algorithms examine the images of the coffee beans. By looking for the presence and concentration of certain molecules, including caffeine, chlorogenic acids and catechin, the AI ​​system is able to understand what is considered a specialty bean and what is a standard coffee bean.

“To be classified as a specialty green coffee bean, it must score above 80 on the SCA scale,” continued Rob, “which ensures consistent quality among specialty coffee beans, which creates consistent, high-quality taste in the coffee you drink at home.

The AI ​​system is currently able to assign a number to each coffee bean, differentiating between specialty beans and standard beans.

“What’s most impressive,” says Rob, “is how quickly these machines are able to identify quality grain from standard grain. Not only does it eliminate the need for roasting and tasting, but it can process a large number of beans at once, speeding up the entire tasting process, all while adhering to SCA guidelines.

Does Rave Coffee use AI in sorting coffee beans?

Currently, Rave Coffee does not use AI-sorted coffee beans. Although AI seems to be a central part of the production and sorting of coffee beans one day, Rave believes in the competence of highly trained coffee producers and sorters.

“All of our growers and partners around the world sort their green coffee beans by hand. This means that every specialty coffee we supply has been tested and rated by a qualified professional. Let it be part of our coffee subscription serviceor our Nespresso compatible coffee pods.

Although we never say never, at Rave we are committed to providing the best coffee to our customers, without compromising our eco-friendly approach and our long-term support of independent coffee growers around the world.

That said, we are excited to see the long-term results of this technology and hope it proves useful for our growers, whether they are based in Brazil, Papua New Guinea or elsewhere.
