A complete guide to coffee bean roasting: from bean selection to roasting, everything is covered!

Bean Selection

Choosing the right coffee beans is the first step in roasting. When choosing coffee beans, we can consider the following aspects.

First, consider the origin of the coffee. Coffee beans from different origins have different flavor characteristics. For example, coffee produced in Brazil has lower acidity and stronger bitterness, while coffee produced in Colombia has higher acidity and a softer taste. Choose the right origin according to your preferences.

Secondly, pay attention to the processing method of coffee beans. Dry processing and wet processing will affect the flavor characteristics of the final roasted coffee. Dry processing will make the coffee more fruity, while wet processing will be more refreshing and soft.

Grinding

Before grinding the beans, you need to determine the required coarseness according to the equipment and brewing method. For brewing methods such as hand brewing or drip brewing that require a longer contact with water, you need to choose a relatively coarse grind; while for quick brewing methods such as espresso or Turkish brew, you need to choose a finer grind.

In addition, the grinding time also needs to be controlled. Generally speaking, freshly ground coffee beans are fresher, so it is recommended to grind them before brewing. And be careful to avoid over-grinding, so as not to produce too much fine powder and affect the taste.

Ratio

When making coffee ratios, you can determine it based on personal taste and brewing equipment. Generally speaking, using about 10 grams of coffee powder for every 150 ml of water is a common starting point.

In addition, other factors can be considered when adjusting the ratio. For example, if you want to increase the acidity and freshness, you can increase the amount of coffee appropriately; if you like a strong taste, you can reduce the amount or increase the extraction time.

Preheat

Before you start using your coffee machine or device, it is very important to preheat it. This will ensure a stable temperature and improve the extraction effect.

For home coffee machines, put in an appropriate amount of boiling water to preheat before use. For hand-brew equipment, you can rinse the device with hot water before proceeding to the next step.

extraction

Extraction is one of the key steps in coffee roasting. When performing extraction, you need to pay attention to the following points.

First, you need to control the water temperature and time. Generally speaking, the appropriate water temperature is between 90℃ and 96℃. Too high or too low will affect the flavor of the coffee. The time is determined according to personal taste and ratio.

Secondly, pour the water evenly and slowly, and maintain a steady speed. This allows the coffee powder to be fully soaked and promotes the full extraction of the aroma and flavor substances in the coffee.

taste

The last step is tasting! When tasting, please pay attention to the following points:

First of all, we should pay attention to the aroma, taste and aftertaste of coffee. Different origins, processing methods and grinding degrees will bring different flavor experiences.

Secondly, it is best to rinse your mouth with clean water before tasting to prevent other flavors from affecting the taste of the coffee.

Finally, you can record your tasting experience for subsequent adjustments and improvements.

Summarize

The above is the main content of the complete guide to coffee bean roasting. Bean selection, bean grinding, proportioning, preheating, extraction and tasting are the key links that need to be paid attention to in the whole process. Through continuous practice and adjustment, I believe you can master a set of roasting techniques that suit your taste!
