Coffee bean production guide: from purchasing to roasting, step by step to teach you how to become a coffee master

Buy coffee beans

Choosing coffee beans is the first step to becoming a coffee master. When choosing coffee beans, we need to consider the following factors:

1. Coffee Origin: Coffee beans from different origins have unique flavor characteristics. Common origins include Brazil, Colombia, Ethiopia, etc.

2. Coffee varieties: Arabica and Robusta are the two main coffee varieties. The former has a more delicate and soft taste, while the latter is richer and stronger.

3. Roasting degree: Choose the roasting degree that suits you according to your personal taste preference, such as light roast, medium roast or dark roast.

Preservation and grinding

Once you purchase fresh coffee beans, proper storage and timely grinding are key to ensuring the best taste:

1. Storage method: Place the unopened packaged coffee beans in a dry, light-proof and well-sealed container. Avoid exposure to direct sunlight to avoid affecting the freshness of the coffee beans.

2. Grind the coffee beans: Choose the appropriate grind size based on your brewing method. Generally speaking, a coarse grind is suitable for a longer brewing time like a drip or French press, while a fine grind is suitable for a shorter brewing time like espresso.

Brewing tips

Mastering the correct brewing technique can perfectly transform coffee beans into delicious drinks:

1. Proportion: Usually, you need to use about 10 grams of coffee powder for every 150 ml of water. Adjust the ratio according to your personal taste.

2. Water temperature control: If the water temperature is too high, the coffee will be over-extracted and produce a bitter taste, while if the water temperature is too low, the coffee aroma and flavor cannot be fully extracted. Generally speaking, 92-96 degrees Celsius is the best range.

3. Cold brew and hand brewing: In addition to traditional drip and espresso methods, you can also try different brewing methods such as cold brew and hand brewing to discover more coffee flavors.

Baking process

If you want to become a true coffee master, understanding the roasting process is essential:

1. Green bean processing: Peel and pulp the freshly picked coffee berries to obtain unroasted green coffee beans.

2. Hot air roasting: The green coffee beans are placed in a professional furnace for heating. Under high temperature, the water gradually evaporates and produces a chemical reaction, which produces aroma and flavor inside the coffee beans.

3. Cooling and storage: After the ideal processing is completed, the temperature of the coffee beans needs to be quickly lowered and stored in a ventilated and dry place. This can maintain its freshness and taste.

Tasting and evaluation

The final step is to taste the delicious coffee you made and evaluate it:

1. Tasting tips: Stir the coffee gently with a spoon, take a sip after inhaling some of the aroma. Pay attention to the feeling when chewing, including acidity, sweetness, bitterness and aroma.

2. Evaluation criteria: Evaluate the flavor characteristics of coffee based on personal preferences and professional knowledge. You can refer to aspects such as acidity, sweetness, taste and aftertaste.

3. Keep trying: To become a true coffee master, you need to constantly try coffee beans from different origins, varieties and roasting degrees, and improve your skills through tasting and evaluation.

Summarize

From purchasing to roasting, learning to make delicious coffee step by step requires time and patience. By understanding the characteristics of different origins and varieties, correctly storing and grinding beans, mastering brewing techniques and understanding the roasting process, we can eventually become masters who truly appreciate and make high-quality coffee!
