If you’re looking for more out of your morning cup of coffee, there’s actually one simple thing you can do — and it won’t cost you a penny extra.

Scientists have found that there is actually a bit of science to brewing the perfect pot of coffee, and one simple trick includes simply chilling the coffee beans before grinding them, according to a University of Bath statement.

To reach their conclusions, scientists tested how bean temperature affect how beans were ground and therefore the ultimate flavor on coffee. A good grind is critical to a good brew, as beans must be ground fine and uniformly. If scientists can figure out a way to grind beans better, it could lead to more flavor with the same amount of coffee beans.

The researchers found that chilled beans had a better post-grind consistency.

The discovery could a big impact on the industry itself, researchers believe, as it could provide an easy way to boost the flavor in a standard cup of coffee.

“Grinding coffee may seem quite straightforward – break coffee up into a lot of tiny bits so you can dissolve it in water,” Maxwell Colonna-Dashwood, co-owner of Colonna & Smalls, said in the statement. “But like the whole world of coffee the subtleties of the process have a huge impact on the flavour and quality of the cup of coffee. The ability to understand grinding more comprehensively has the dual impact of allowing us to make better tasting coffee and to be more efficient in the way we do that.

“The research suggests that temperature of bean needs to be more constant to help us achieve consistent grinds. It suggests that cooler temperatures will allow us to maximise surface area and utilise more of the coffee. All of this will impact on how we prepare coffee in the industry, I bet we will see the impact of this paper in coffee competitions around the globe, but also in the research and development of new grinding technology for the market place.”
