The roasting of coffee is realized in three stages.

Soft, silky Colombia coffee, unique aroma, slightly sour blue mountain coffee, syrup and chocolate flavor, balanced aroma of Indonesian coffee... More than 50 countries around the world produce more than 3000 kinds of coffee beans every year, so, if the origin of the standard, in many choices to choose the most suitable coffee is really not easy. Some experts believe that the roasting of coffee beans has a more direct impact on the taste of coffee. Understanding the different tastes and flavors that different types of roasting bring to coffee is undoubtedly a "shortcut" to choosing your ideal coffee.

Coffee roasting is accomplished in three stages. In the light baking stage, when the beans emit the first soft sound, the volume expands and the color changes to cinnamon. Acidity dominates the flavor of light baked beans, texture and taste are not fully developed. At the medium roast stage, 10 to 11 minutes into the roast, the beans take on an elegant brown color. This method of baking is also called city roast. Medium roasting preserves the original flavor of coffee beans and releases aroma moderately. Deep roast, coffee fat began to surface, beans were burned by the fire to a bright dark brown, the darker the color of coffee beans, the sweeter the flavor, then the fat has become caramel, bitter to sweet, endless aftertaste.

Starbucks coffee roasting master Doug Langworthy introduced, and in the past simply from the origin to distinguish products, according to the depth of baking to distinguish products, can let consumers more "at a glance" to choose their favorite taste. "Different baking methods will bring very different feelings, consumers can easily choose more suitable products according to their own preferences."

Different baking methods create personality

"Light baked, mellow, light in flavor, subtle and rounded. Medium-roast coffee is medium-bodied, balanced and smooth in flavor; deep-roast coffee is rich and thick in purity, rich and intense in flavor." The effect of different roasting methods on coffee flavor is particularly evident.

Light fried coffee beans are usually light brown, will have a strong smell, very crisp, with a slight alcohol, high acidity is the main flavor. Medium-fried coffee beans are light brown in color and have a strong alcohol content, while retaining most of the acidity. Deep-fried coffee beans have turned dark brown, often with a layer of shiny oil on the surface, acidity replaced by a slight burnt bitterness to produce a spicy taste. Some of the extra deep-fried coffee beans even contain a bitter taste of charcoal ash, which is significantly reduced in alcohol.

"Different roasting methods can make very well-balanced and excellent coffee." Doug Langworthy said that in fact, different roasting methods can only represent different personalities and styles of coffee, just like different personalities of people, but there is no difference between good and bad. Doug Langworthy himself has a soft spot for Starbucks 'light-roasted "golden roast coffee." "I like that kind of soft touch. Professional coffee roasting is a personal expression of the master."

Find your favorite by smelling, inhaling and tasting

Just as wine requires certain skills and methods, coffee requires various necessary steps. To know how to choose the type of baking that suits you, you first need to know how to "taste" to distinguish the different feelings brought by different baking types.

The first step is "smell." Smell and taste are actually directly interlinked, and when people judge whether food is delicious, they often start with smell. At the same time, differences in taste can already be detected among different types of roast coffee. Light roast coffee, aroma soft with a sweet and balanced feeling; medium roast coffee taste the most "coffee" feeling, mellow and layered. At the deep roast, the smell is rich and there is a distinct "sweet" and "slightly burnt" feeling.

After getting an initial impression of the different types of baking from the smell, you can move on to the second step of the tasting: sucking. This is also the full use of nasal and taste buds, so that smell and taste work together. Take a big sip of coffee and let the flavor rush straight into your nose. You can directly and strongly feel the aroma of this roasting method and further verify the feeling of the first step of "smelling". Through this "smell" and "suck", the three types of coffee must have a fresh outline and personality in your mind.

Of course, knowing what you really like has to start in more detail. So, the third step is the sipping phase. Put the coffee into your lips and sip it carefully. Let the coffee flow slowly from the inside of your lips to the tip of your tongue and then slowly to the middle of your tongue. Let the taste buds in different parts feel the fine layers of coffee. At this point, if your tongue is sensitive enough, you can distinguish some berry aromas and sweetness that may appear in light baking, chocolate and cinnamon that may appear in medium baking, caramel flavor that may appear in deep baking, spice flavor and a little bitter... Of course, these details vary greatly, but through the three-step tasting, you can more clearly find the type of taste you want.
