You can share your coffee brewing experience on social networks.

Coffee And Green Beans Are Not The Same

Colombia or Ethiopia? Water washing or honey treatment? Bourbon or tiebica + kadura hybrid? There are many properties and differences of green beans to be considered. It will not only affect the taste but also affect how you bake the beans.

The following are some key factors to consider:

1. Place Of Origin:

That is, the environment in which the coffee is grown, including climate, humidity, soil, etc., affects the aroma and flavour of the coffee. Gradually narrow down the selection criteria from a broader range. Compare coffee beans from different production regions and countries before comparing differences between batches and farms.

2. Variety:

Coffee can be divided into 'varieties' and 'breeds'. Varieties are listed under varieties, and varietal differences can have a significant impact on the flavour of the coffee. Tasting a Geisha, Yellow Bourbon, or sl-28 can bring a completely different sensory experience.

Do you buy coffee beans to grind fresh coffee grounds, or do you buy pre-ground coffee for daily brewing? No matter which method you use, do you know where these coffee beans are produced?

3. Altitude:

Generally speaking, there will be a lower temperature at a higher altitude, which will slow down the growth of coffee fruit, and then make the fruit develop a higher sweetness. Finally, such coffee will have a richer flavor and sweetness, and the acid quality will be better than that of low altitude beans.

When considering altitude, don't forget that different areas have different temperatures. For example, in Hawaii, it would be too cold to plant coffee at an altitude of more than 600 meters, but Kona in Hawaii is quite famous. However, in the Cologne islands of Ecuador, coffee grown at an altitude of 200 meters can be defined as fine coffee. These should be taken into account when assessing the altitude of coffee cultivation, especially coffee from different producing countries or different continents.

4. Green Bean Treatment Method:

The whole fruit of sun / dry treated coffee will be directly exposed to the sun, and then the outer pulp will be removed, making the coffee beans sweeter and more fruity. The washed / wet treated coffee will remove the pulp before drying, so it will have less sweetness, but at the same time, the flavor is higher and the acidity is brighter. Honey treated coffee will first partially remove the pulp and leave part of the pectin layer for exposure, which makes honey treated coffee sweeter and fuller than washed coffee.

In addition to the three common treatments mentioned above, there may also be treatments such as monsoon treatment, wet stripping treatment, and fermentation test methods, which usually fall into specific areas. For example, monsoon-treated coffee will only be stored in warehouses in India during the rainy season.

How To Find The Right Coffee For You

Before you know what kind of coffee you want, you must taste it first, and taste it in large quantities.

Try different types of coffee, and take notes on each type of coffee. Try to give each cup of coffee a score of 1 to 10, and then add notes on sensory feelings, such as acidity, sweetness, alcohol thickness and taste, and aftertaste. You can also mark the flavor and aroma of the coffee, whether it is your favorite flavor or not. If you can obtain information, you can also write down the basic information such as the production area, variety, altitude, and processing method.

If you're brewing coffee baked by someone else, watch the coffee beans and note the roasting temperature. Is there any oil on the surface of the beans? Do you have a chocolate color?

The roasting degree affects the flavor and aroma of coffee. Generally speaking, the shallower the roasting degree, the easier it is to taste the original special flavor of beans, including fruit aroma and acidity. Because the roasting process will add the flavor of the baked beans, and these flavors can easily cover the natural flavor of the beans. Deep roasting usually has a thick taste, low acid, and rich oil on the surface of beans.

If circumstances permit, you can order a cup of single coffee in a boutique coffee shop, which will give you the opportunity to learn about these coffees with a barista and identify the bean flavor of different production areas.

Practical Points Of Procurement

There are many green bean sellers who can sell green beans online and ship them around the world, but before you place an order, please ensure the final cost, availability of beans, and other practical points.

After all, coffee is a crop and has its harvest period. However, different countries have different harvest periods. Just like fruit and bread, the freshness of the beans affects the quality of the coffee. Most people don't want to buy old beans or beans that are more than a year old.

In addition, some sellers are only willing to sell green coffee beans in bulk. Once you have bought so many green beans, will you want to roast and consume them? Even if you could use them up, do you have enough storage space to properly store the green beans?

You can discuss anything about coffee with other coffee lovers on the forum.

Once You Buy Green Beans

Now that you know more about coffee beans, you find some samples for comparison and make cup test notes. At this time, you finally need to buy some green beans and bake them at home.

You can experiment first, select a production batch of coffee, and use three to five different roasting methods to present this coffee. Then select different batches of coffee and bake these different batches with the same roasting method. Recording and comparing the results of these two groups of experiments will help you understand the application and relevance of roasting degree and different coffee beans. Then repeat these actions: match different coffee beans with different roasting levels until you bake your favorite coffee flavor.

The cup test also allows you to get a lot of information in a short time, by tasting several cups of coffee at the same time and recording the flavor. Learning how to cup test also helps to assess the quality of your roasted coffee.
