Fresh roasted coffee is every coffee drinkers dream. Not every coffee drinker understands the process of how coffee is made, including the roasting process. To understand it a little better lets go through the basics.
Processing
A good coffee always starts with a good bean. This is where coffee starts to differentiate as far as brands are concerned. Some places use processors that will was the beans to remove the fruit of the bean and separate out the different densities of beans. Less dense beans will float to the top where they can be easily removed. Some use a slow dry process. Dry processed beans have a subtle acidity compared to the higher acidity of wet processed beans. The acidity level is what gives coffee its flavor. Without acidity it tastes flat. An important factor of good processing is that it should leave the bean with a good moisture content so that the flavors can develop in the roasting process.
Roasting
Roasting allows the beans to produce levels of acid, aroma and other flavors. The first stage of roasting turns a green bean into a yellow color and creates a smell similar to popcorn. When the next stage is reached, at 338F-392F, the sugar in the beans starts to caramelize. It is important that the sugars caramelize or the coffee will be too sweet once brewed. At 400F the next stage begins and the beans double in size and lighten in weight. The temperature will rise to 428F the bean reduce further in weight and release CO2. At 446F the beans become oily and there is usually a pop sound. This is a critical stage where the beans can be over roasted if the roaster is not careful. The oils and aroma start to boil off and combine with air if this is overdone then the beans will lose flavor and take on a burnt taste. Achieving a balance of bitterness, acidity and other characteristics is the goal in this final stage.
The Perfect Taste
Tasting guides will often use the term body to describe the kinds of proteins and fibers in the final brew of coffee. It refers to how the brew tastes on the roof of the mouth. It is determined by the roasting process. Too light of a roast will be too bitter, while too dark of a roast will take on the aforementioned burnt taste. Neither is considered the perfect roast. It should fall somewhere in the middle with a good balance. The type and brand of espresso maker can make a difference as well.

The best coffee comes form the freshest beans possible. It can be a challenge to get the freshest coffee unless you have a coffee bean field outside your back door. There are ways, though, that you can try to have the freshest coffee possible. When it comes to a good bean, there are a few factors to consider.
Roasting
Roasting is a complex process. It is actually cooking and therefore should be looked at as a complex art. There are right and wrong ways to roast beans. If done improperly the results will be beans that are less than desirable. Roasting beans yourself is something that is a hard task. You would need roasting equipment and even then you would have to know how to do it, which can take along time to learn properly. After roasting beans will stay fresh for quite some time, so buying roasted beans is fine. You should understand, though, that beans are freshest when ground right after roasting and keep that in mind.
Storage
Since you will likely be buying your beans already roasted, storage is very important to maintaining freshness. Beans are the best when ground following roasting. The more time that lapses, the less fresh the coffee will be. However, they can still be fine after a few days. You wan tot store them properly, though. The skin should remain in tact lest useful oils are lost and the bean will go stale. The container used to store the beans should be airtight. A rubber sealed jar is the best choice. It should be left in a cool, dry place without any light or heat which can spoil the beans.
Grinding
You can grind your own beans at home. This is not nearly as difficult as roasting. There are many different ways to grind beans and the different methods produce different tastes. You should learn about grinding before trying it. This will allow you to create the coffee you desire. Ground beans should be used a soon as possible since they can go stale quickly. They should be protected form air and moisture in a tightly sealed container. The oil in the grounds can evaporate leaving behind a stale coffee. It is best to grind only what is needed.
In the never ending saga of the rush to find the perfect cup of coffee, the coffee expert can struggle. Many times that is because their coffee is just not fresh enough. By leaning things about grinding storage and roasting you can be better trained to learn how to go about creating that perfect cup of coffee. In fact, it is only through learning about the science behind coffee that you can truly understand it. You may know about all the differentials when it comes to certain aspects of coffee, but until you truly understand what makes coffee fresh you will never be able to make that perfect cup.
