Green Coffee Beans To Roast

By Elnora McCullough


Roasting your own cup of joe can be a fun and easy experience or something challenging and technical. Some accomplish the task with simple tools like a cast iron skillet while others buy expensive commercial roasters that automatically stop at the desired darkness of the bean. No matter how you set out to do the task, you will need to purchase green coffee beans to roast.

Roasting time is relatively short but dependent on the method selected and the darkness one wants. Using a converted popcorn popper, most consumers prefer about 8-12 minutes. In the frying pan or roasting in the oven takes 14-18 minutes. Once finished, the product should be cooled quickly, allowed to sit for a day to degas.

In order to select the appropriate roasting method, one should consider the amount of the product that will be used and the money he or she is willing to spend. Roasting in the oven or frying pan is the cheapest, but may result in uneven roasting. The converted air popper works well, but it is getting hard to find the right popper. Commercially built machines are the most expensive.

Coffees have different flavors depending on the regions where they grow. In addition, the time in the roaster affects the flavor as well. It can sometimes take some trial and error to determine the region one prefers.

Roasting hobbyists will want to understand the process of roasting to find the flavor they desire. In the first few minutes under heat, the color will begin developing into a pale yellow. The smell is much like grass. As temperatures steam starts to escape as water begins to evaporate.

As the process continues, it is common to hear a cracking or popping sound known as first crack. The noise is due to the expansion of the bean due to caramelizing of sugars and escaping water. Oils also start to be released.

Once the product reaches the first crack state, the individual may consider the product done according to his preference. One can use sounds, smells and sight to determine the right time. For those desiring a mild flavor, roasting should stop at immediately after the first crack.

Heating further causes additional caramelization and volatile oils to move to the surface. Each bean starts to expand and grow darker. Most consumers prefer their brew from beans somewhere between the first and second crack. Stopping just before the second crack leads to a full bodied drink.

The second crack stage can be much more volatile and may cause flying particles from the product. After the second crack, the product it at the Vienna state. This dark blend will begin to express some smoky flavor.

Continuing to heat results in a much stronger smoke as the sugars burn more completely and the vegetable matter breaks down more. This is the French product. It is very bold and Smokey.

Green coffee beans to roast offer a flavorful brew at one's home. The product is often better than anything that can be bought in a store. Remember, each bean begins to oxidize as soon as it cools.
