In what may be the biggest DIY cannabis extracts innovation since rosin tech, researchers in Spain have discovered a way to make quality concentrates using an espresso machine and a common solvent.

The study, done at the University of Valencia in Spain, is called “Fast extraction of cannabinoids in marijuana samples by using hard-cap espresso machines.” It will soon be published in The International Journal of Pure and Applied Analytical Chemistry, but we learned about it from The Marijuana Times.

Their method was relatively simple, but groundbreaking. The research team used cannabis which had been confiscated by authorities and put it into their espresso machine along with the laboratory solvent 2-propanol.

Researchers reported that the cannabis concentrate they produced was similar in quality to that achieved through more common extraction methods. However, their method took much less time and was a lot less costly.

Traditional extraction setups can cost upwards of thousands of dollars, but the researcher’s espresso machine only cost about $300. They used it to manufacture THC, CBD, and CBN extracts.

“It has been evidenced that the developed method for the major cannabinoids extraction is a really encouraging example of the wide range of possibilities that a conventional and low cost hard cap espresso assisted extraction could offer in analytical laboratories,” the study reads.

As The Marijuana Times pointed out, that doesn’t mean that every Dick and Debbie Dabber out there should run out and grab an espresso machine to make their own concentrates. “The extraction method is safe and effective for use in a laboratory setting by professionals who know what they’re doing, but … more studies and experimentation need to be done in order to determine if an espresso machine extraction method can be replicated and utilized in various other settings outside of the lab,” the publication wrote.

Interestingly, this is not the first innovative use of the hard-cap espresso machine. As Science Daily has reported, chemists have been using it for years as an inexpensive technique to conduct complex experiments such as testing for harmful compounds in the environment.
