A coffee roaster creates an amazing chemical transformation – the Maillard reaction – that transforms over 800 compounds in raw beans into delectable flavours.
During the Maillard reaction, the sugars, starches and fats inside the bean undergo a series of minuscule changes.
These alterations influence how your cup tastes. As a rule, lighter roasts tend to be less acidic and have more body than dark roasts.
Light Roast
Light roast coffee beans are roasted for a shorter time than dark roasted beans. These roasts usually occur at a temperature of around 385-400 degrees Fahrenheit and are just long enough to pass what is known as the first crack, or the stage where moisture evaporates from the surface of the bean.
The result is bright, fruity, acidic notes, a light brown color, and a dry, rather than oily, texture. This type of roasting stops before some chemical changes occur inside the bean, which helps preserve flavor and quality.
A light roast can have a slightly higher caffeine content than other roasts, however. This is due to the fact that the beans are a little more dense than dark roasted ones.
Generally, light roasted beans taste more delicate than their darker counterparts, so it is important to use high-quality beans. The best light roasts are typically African beans from Ethiopia, Tanzania, or Kenya.
This type of coffee is suited to slow brew methods like drip, French press, and pour over. Cold brew is also a good choice, since it can bring out the sweeter, fruity notes in the coffee.
Medium Roast
Before คั่ว กาแฟ, coffee beans are green and soft. The roasting process transforms these flavorless beans into the rich, aromatic cup of coffee we all know and love.
Coffee is roasted in a variety of ways, depending on the type of coffee bean it is made from and the desired taste. The roasting process is one of the most important factors in determining a coffee’s taste.
The color of a roasted coffee bean is the most commonly used indicator to determine its level of roasting. Light roasts are typically a light brown color with little or no oil on their surface, while dark roasts are usually a deep brown to black with an oily sheen on their surface.
Medium roasted coffees are usually darker in color than light roasts and look richer. They are also a bit thicker than light roasts and start to show more of the coffee’s oils on their surface.
In terms of taste, medium roasted coffees are sweeter and more balanced than dark roasts, with a fuller body and a smoother flavor. They are also less acidic than dark roasted coffees and contain a lower amount of caffeine.
A coffee brewed with medium roasted beans can be served in a wide range of brew methods, from cold brew to hot double-strength pourover. It will taste its best when brewed using a filter and allowed to steep for four minutes or more.
Dark Roast
When you roast your coffee beans, there are different types of roasting that give your coffee a specific taste. Whether you’re a lover of coffee or just looking for a new drink, understanding the different types of roasting will help you choose the perfect type of coffee for your taste preferences.
Light roasts are the type of roasting that you typically see in single origin and milder coffees. They are roasted for a shorter time so that the coffee beans can release their caramelized sugars and retain their natural flavor.
Medium roasts are the next step in the roasting process after light roasts. These beans have been roasted for a little longer. They enter the cooling sieve right before the second crack and are a bit darker than lightly roasted beans.
They’re slightly less acidic and have a slight amount of caffeine but they also have a richer, more complex flavor than dark roasted beans. You’ll find that this type of roast is often more appealing to people who like a more full-bodied cup of coffee.
There’s a popular misconception that dark roast has more caffeine than light roast, but this is a myth. This is because it’s not the roast level that determines caffeine content.
