The main goal of this particular article is to present you a comprehensive understanding of life cycle assessment of coffee that includes carbon emissions, total energy, water use, waste and everything that you should do throughout the life cycle.
Life cycle assessment or LCA is the best way to analyze the entire product or service from the very beginning until the very end.
It uses a systematic methodology that will quickly evaluate the life cycle of the entire product, and life cycle includes outputs, inputs as well as energy analysis of all materials that you have used for it.
Let us start from the beginning:
Before you can make your favorite beverage, the process begins with growing and treating the coffee plant. It is essential to understand that the coffee plant tends to start from a bean, which means that you should plant it in soil.
Therefore, in the next four to eight weeks, the seedling will start, and you have to place it in shaded location because it will become sensitive to direct sunlight, so you have to find a site that will protect it until the next step.
You should also remember that seedling requires tending so that it can grow in the next nine to eighteen months, and finally, it will reach two feet of height.
The next step is to place the coffee tree into the ground, which means that it will bear fruit in three years, while in six years it will reach maturity and perfect yield. Finally, after six years it will reach full maturity and yield which will provide you the highest amount of beans.
You should also remember that the coffee tree can produce for the next twenty years at least.
The next step of coffee production requires roasting so that you can enhance the flavor of raw coffee bean, which tends to be green after you pick it up.
During the process of roasting, the chemical reaction will cause it to destabilize and enhance the flavor, which will provide you the enjoyment you have every single morning while drinking your favorite beverage.
The destabilized coffee can easily remain fresh and tasty for the next month, while green or raw coffee can continue much more extended than destabilized one. Have in mind that roasting is the process that manufacturers create so that they can send to end-user who will drink it afterward.
The process of roasting includes sorting the beans from the debris and mixes it all. As soon as you type everything and weight it inside the batch size, the idea is to place it in the roaster that you have.
The process lasts between three and thirty minutes, depending on what you wish to get from it. The temperature tends to range between 180 and 280 degrees C, and the length of roasting will affect the flavor and strength that you wish to achieve.
Remember that less time it is roasted, the color will be lighter and the strength will be weaker. At the same time, the flavor of the light roast is based on raw or original taste, which will provide you similar efficiency as climate and soil in which you grew it in the first place.
Similarly, as a light roast, if you do it longer, the coffee will get dark color because the process of roasting will bring the chemicals and flavor that will increase its overall strength. The darker roasts are shinier than the light one because the process will also extract oils from the inside.
At the same time, the dark roast creates the intense flavor, in which roast is dominant, while you will not be able to enjoy in original character similarly as light roasted coffees.
Have in mind that coffee tends to grow all across the globe and imported for billions of people. The central portion of coffee production emissions and costs come due to the transportation process.
At the manufacturing plant, the transportation starts from the field to it and between processes we have mentioned above. As soon as it leaves the plant, the coffee will be shipped with trucks and boats to the desired location.
Finally, if you wish to make a perfect cup of coffee, you have to ground it to reach the ideal consistency and use boiling water so that you can consume it afterward.
The entire process is called brewing, and through it, the extraction of caffeine, and it will extract the coffee flavor from roasted beans. Have in mind that grounds should not be boiled with water because the process will impair a lousy taste in general.
We can differentiate three methods of brewing coffee: boiled, steeped, and pressurized.
Steeped Coffee - When it comes to steeped coffee, have in mind that it requires a French press machine. We are talking about a device that comes from glass, and that contains a plunger filter that will fit in the glass cylinder. The idea is to place a combination of coffee and hot water within the machine and brew it between five and ten minutes.
After brewing, the idea is to press the plunger down so that you can separate coffee solution with grounds. Therefore, the process will make a stronger cup of coffee since the properties will remain in hot water much longer than before. The longer the water stays in contact with the grounds, the more coffee oils and flavor will be extracted from the grounds in general.
Boiling Coffee - This is the oldest brewing technique, which is traditionally used by placing water into a pot and boiling it, and afterward using coffee grounds so that you can create a perfect cup without any additional problem.
The idea is to boil it for long as you like based on the taste that you prefer. Finally, you should place the liquid inside the cup and consume it with enjoyment. Have in mind that liquid may contain grounds at the bottom of the pot, but the result will still be strong and tasty.
Pressurized Coffee Brewing - This particular type of making coffee includes two sources of pressure such as pressurized water as well as gravity pressure. Gravity pressure is known as drip coffee, which is one of the most popular methods in the USA.
The idea is to fill the filter with grounds while hot water will flow through them. Gravity will cause the water to flow down through them, and liquid will drop out of the filter before you consume everything. On the other hand, pressurized water brewing is known as espresso, and it uses a mechanical device that will pressurize and heat the water while forcing the hot water flow through grounds.
