We all love freshly brewed coffee. Don’t we?
However the freshness and the aroma of the coffee does depend on all of the factors starting from the plantation, roasting, storing, grinding to the brewing of the coffee. Although, we cannot control the factors related to the plantation, we can be sure that if the beans are sourced from a good company, quality is always assured.
But as we see here rest all the steps to produce that great cup of coffee depends a lot on us. However, the proper storage of the coffee beans affects the aroma and quality of the brewed coffee a lot, and hence today we are going to limit our discussion in the best way to store roasted coffee beans in home.
Transformation of Green Coffee Beans to Roasted Coffee beans.
The green coffee beans when plucked from the shrubs are non aromatic hard and flavorless beans and most of the transformations take place during the roasting process. And also the roasting technique can generate different variety of flavors as the chemical reactions starts and stops depending on the temperature, duration and other factors.
The green or raw coffee beans consist of several organic compounds like carbohydrate, lipids, proteins, poly-phenols, caffeine and several others. These by themselves are not aromatic and are not directly responsible for the flavor.
However these same chemicals turn into heavenly aromatic flavor when they are craftily roasted at high temperature and pressure for certain duration. Resulting in volatile organic compounds like 3-isobutyl-2-methoxypyrazine and many more under the Maillard Reaction.
During the reaction a lot of transformation takes place inside the beans and as a result the beans releases a lot of carbon-dioxide(CO2). Maximum of the CO2 is released during the first 48 hours and it slowly decreases over a period of seven days.
As a matter of fact, this carbon dioxide both helps to keep the coffee fresh by creating a barrier between the beans and the atmospheric Oxygen, and also producing a thick crema. And hence you will always find freshly roasted and grounded coffee will always produce a lot of crema.
How To Store Roasted Coffee Beans?
During our day to day life we require easy and hand solution for our problems, and so we are going to see the best way to store coffee beans and the elements we should protect them from.
The storage unit should have the below mentioned properties to keep either coffee beans or grounded coffee fresh:
- Protection from Light: The coffee beans needs to be protected from light pretty well as light catalyze the decomposition reaction.
- Protection from Moisture: Moisture degrades the quality of the coffee and gets the entire aroma swamped. Hence both beans and the grounded coffee should be protected from moisture.
- Protection from Heat: Coffee is sensitive to heat once it has been roasted, keeping on constant high heat for long duration degrades the quality of coffee and hence it should be protected from heat. However, that does not mean we should keep the coffee beans or the grounded coffee in refrigerator, as that increases the chances of letting the moisture in. Keeping in normal cupboard is fine enough to keep the coffee cool.
- Should have one way Ventilation: As we mentioned above, newly roasted coffee releases CO2, and it’s good for the coffee. But this CO2, needs to be vented out from time to time, or simply put the coffee should be able to breathe.
- Should have air tight seal: The storage container should have an air tight seal, to keep the Oxygen out and hence prevent the oxidation.
Considering the facts that you will need only a few storage places or jars for several years, we are giving the best way or options to store roasted or whole coffee beans.
