Roasting coffee beans in a popcorn popper steps
We put the fresh coffee beans in the Popcorn Machine and when it starts to heat you will see that the cuticle that wraps around the coffee bean, gently peels off and the color changes from light green to yellow, assuming different colors to dark brown.
#2 The Coffee begins to steam and crackle
As with popcorn, when coffee is roasted it inflates and doubles its volume. When the coffee begins to steam and crackle like popcorn, it is a sign that the roasting begins after about three minutes. At this point, we can decide the level of roasting, and then continue to work the coffee until we achieve a burnish that we consider more appropriate, according to the taste. Never fill the popcorn machine more than halfway through its level.
When it is roasted, we put the coffee beans in a container and let it cool down to room temperature, they are placed on a tray and after checking that there are no pebbles and that all the beans are perfect, we cover it with a sheet of transparent film and let it rest in the freezer for about 15 minutes
You can put the coffee beans in hermetically sealed bags, preferably vacuum-sealed, or in an airtight jar and leave it in the refrigerator for at least 5-6 days before grinding and consumption.
Once ground, you can brew the best cup of coffee and taste the intense and enveloping flavor. for a good cup of coffee, we need before that a good preparation
The main transform on the coffee beans during Roasting
Green coffee beans are seeds with dense and compact structures. But when you put them in the roaster, their original shape changes completely. Let’s see what physical changes occur.
The Color of coffee beans
Perhaps the most obvious change that occurs during roasting is that of color. Before roasting, the coffee beans are bluish-green. They then turn brown. There are molecules called polymers. these molecules are formed when sugars and amino acids are mixed with the application of heat. Besides, during roasting, the husk or silver film will be removed, that is, the external layer of the coffee bean that looks like paper.
Roasters and consumers use the degree of coloration as a parameter of quality
Humidity and Mass
Green beans that have been dried and processed are composed of approximately 10 to 12% water, but roasting decreases this amount to about 2.5%. In addition to the water already present in the green beans, chemical reactions generate additional water. However, this water evaporates during roasting.
The decrease in humidity and the transformation of some parts of dry matter into gases are the reason why the beans have a lower overall mass after roasting. On average, grains lose between 12 and 20% of their weight. Roasters often monitor the percentage weight loss so that they can identify which lots should be examined more carefully for quality assurance.
Different roasting profiles will have an impact when dehydration occurs. Changes in water activity at different points in the roast can mean a difference in chemical reactions and this could affect the final profile.
Types of coffee roast, Light Roast vs. Medium Roast vs. Dark Roast Coffee
The type of roasting will vary according to the time the grain is in the toaster.
As time passes, the grain darkens, and to simplify, we will have 3 main types of toasting: low, medium, and Dark roast coffee
Low or light roasting
Cinnamon colored, very acidic, and with a lot of caffeine.
Medium Roast or American roast
Generally, for the filter, it is the most traditional for its taste and aroma. It has medium acidity and caffeine.
Dark roast coffee
The French roast is a high, dark brown, fat textured roast for full-bodied coffees.
The Italian Roast, is one of the very high coffee roasts, with maple aroma for many the preferred ones to make espresso.
It is preferable to roast in a space that is not closed and that is protected from the wind. There may be a lot of smoke.
If you don’t want to use epoxy, measure the width of the popcorn machine’s chamber. Look in the foreign food section of the supermarket. Many cans come in different sizes. Popcorn machines have a slight tilt in the bottom. The can should stick out about eight inches. So a can that is 10 or 12 inches long and the width of the popcorn machine will slide into the narrow area and hold in place.
Keep an eye on the process at all times. Be extremely careful when handling hot items.
Do not roast more than you can use in a few days. Coffee tastes best from 3 to 8 days after roasting.
