Out of all of the types of coffee in the world – espressos might be the one that people are least fussy about. After all, it’s basically just a shot of highly concentrated black coffee.
An espresso isn’t exactly something the average person will savor. You’re just supposed to down the tiny drink, like a shot, get a quick boost of energy, and carry on with your day.
But what if we told you there were actually a lot of people out there who care deeply about the quality of their espresso? Not only that, but many have obsessed about the perfect way to prepare it.
Now, a team of scientists have made a pretty huge claim – they have found the secret to a perfect espresso.
What’s the Secret?
Researchers have stated that if you add just a dash of water to the coffee beans before you start the grinding process – then the end result will be far tastier and more consistent.
It sounds incredibly simple, but it’s a technique that many coffee aficionados just aren’t that familiar with.
Why Does Water Make Such a Huge Difference?
Apparently, when the grinding process starts, electricity is created from the friction in the beans. However, when water is added to the process, there is actually less electricity, and as a result, the flavor is stronger.
These findings were published in the journal “Matter” after a collaboration was struck between researchers and, surprisingly, volcanic experts.
According to electrical and computer engineering assistant professor, Joshua Mendez Harper, magma breaks down into smaller particles after a volcanic eruption. Then, lightning is produced after the particles rub against each other.
“In a simplistic way, it’s similar to grinding coffee,” he says. “Where you’re taking these beans and reducing them to fine powder.”
What’s Next on Their List?
According to chemistry professor Christopher Hendon, these researchers want to work out what is the secret to the perfect cup of coffee.
We’d recommend watching that “Breaking Bad” episode when Walter White’s lab partner creates what he believes is the greatest coffee he’s ever tasted. In our opinion, that would be a good place to start.
