Coffee is one of the most popular drink choices, and it has different versions around the world. The roast is the key to some of the many different brews and flavors. How the coffee beans are processed changes the taste, the smell, the caffeine content, and what types of drinks it is best used for.
Roast refers to how long they are roasted and the color they are when they are finished. When coffee beans are picked, they are raw green coffee beans, and roasting them is how the flavor and aroma from within are released and prepared for brewing. The coffee beans are heated quickly, and once they have reached their intended roast, it is stopped, and they are cooled as soon as they are heated. By quickly making the temperature changes, there is improved control over the final results.
Usually, the roasted coffee beans suppliers provide the roasted beans in four categories – light roast, medium roast, medium-dark roast, and dark roast. These will have their own versions and flavors within, and many businesses and even individuals will perfect their own perfect roast.
Within the light, roasts are different roast levels:
- A light city roast that offers the shortest roasting point.
- A half city that is slightly darker.
These roasts can be used on any variety of coffee beans, and the taste of each will vary depending upon where the coffee bean is grown and which variety it is.
Medium roasts can be further broken down into a city roast, American, and breakfast. Popular at Bun Coffee beans in Sydney, all across Australia, and throughout the USA, the American roast is widely used and can be found in many different coffee-based beverages and espressos. However, the medium-dark roast that is most often created is a full city roast and offers a balanced taste that is the choice of many.
Dark roasts are those that are roasted the longest and will have the least caffeine. It is offered in many different selections with the strongest taste and a touch of the bitter taste. Popular dark roasts include high, continental, New Orleans, European, espresso, Viennese, Italian, and French.
The caffeine content in each coffee bean will vary not only depending on the roast used but also on how the coffee is measured. When coffee is roasted, it loses weight and becomes less dense as the water content is depleted. Therefore, the caffeine that remains is found within the ground coffee and will be higher when more grounds are used for the brew than when smaller amounts are used. This makes the way in which the coffee is measured, volume versus weight, the key factor in determining the caffeine content in each cup of coffee.
Sometimes the best way to determine a personal preference is to try different versions and see which you prefer. Coffee is one of these items, and various sources, roasts, and brews will all taste and smell differently, making it both enjoyable and necessary to try a few in order to determine which is the best fit.
