Getting ready in the morning for work can be a challenge, especially if you have kids. For most, brewing fresh coffee is an essential part of the morning routine. So the question remains, can I freeze coffee beans to preserve a better taste? The answer is yes, as long as you prepare for a slight change in taste.
From high-tech coffee machines to percolators and French presses, there is not much that people haven’t tried in pursuit of great coffee. A few studies have revealed techniques for achieving better coffee flavor.
You can freeze the roasted coffee beans…
Time for a physics lesson. When coffee beans are ground cold, the resulting grains are much finer. Finer grains allow more surface area of the coffee bean to be exposed to the water. This can provide a deeper and more rich flavor.
Grinding coffee beans to very fine consistencies is a well-known technique. Large coffee mills have grain-size adjustments, and they are often adjusted for the best results. Since home coffee mills do not have settings that allow for very fine grinding, freezing the roasted beans can help you achieve finer grounds.
Roasted Coffee Beans in the Freezer
For the scenario above, the roasted coffee beans were only left in the frozen state for a couple of hours. At home, a batch of roasted coffee beans is more likely to be left in the freezer for a week or more. The length of time frozen can make all the difference.
Deep freezers work best…
Coffee beans treated to fluctuating temperatures tend to lose their flavor. Try storing roasted coffee beans in a freezer that is not opened routinely throughout the day.
The Frozen Coffee Bean Taste
Some coffee experts believe that very finely ground coffee tends to taste more acidic than coffee that is more coarse. Whatever the case, freezing roasted coffee beans is a practice used by many coffee experts. Find what works best for your morning routine, and at the same time, satisfies your desire for your morning coffee.
