It's almost the annual "Double Eleven" Chopping Day, is your purse ready?
A friend left me a message, let me introduce more about how to buy coffee beans, just close to double eleven, there may be a lot of good discounts in stores, after reading this article, you can rest assured to pick the most affordable beans!
There are currently more than 100 types of coffee in the world, the two most common of which are Arabica and Robusta/Canephora. Both coffees are very different in taste, composition, and growing conditions, and we will compare the differences between the two.
Arabica: Expensive, supple, low in caffeine
Coffee advertisements often emphasize that they use 100% Arabica coffee. Yes, Arabica is indeed more advanced in terms of price alone, and the price of Arabica coffee beans is generally twice that of Robusta.
In terms of ingredients, Arabica has a low caffeine content (0.9-1.2%), 60% more fat content than Robusta, and twice the sugar content, so the taste of Arabica is sweeter, softer and with a bit of plum-like sourness.
In addition, Arabica's chlorogenic acid is lower (5.5-8%), and chlorogenic acid in addition to antioxidant, is also an important component of resistance to pests, so Arabica is more susceptible to pests, but also susceptible to climate influence, generally planted at higher altitudes, the fruit is less and slower. The fruit is oval in shape.
At present, the largest grower of Arabica is Brazil, while Colombia produces only Arabica coffee.
In addition, we can also see in a lot of coffee information: Bourbon (Bourbon/Bourbon), yellow bourbon (yellow bourbon), Caturra (Kadura), Catuai (Kaduai), Typica (Tin Pickup) and so on, in fact, these are different varieties of Arabica coffee.
Robusta: Cheap, bitter, caffeinated
In contrast, Robusta, which is higher in caffeine (1.6-2.4%), lower in fat and sugar, has a bitterer and stronger taste, and some people even unceremoniously say that it has a rubbery taste.
Robusta has a high content of chlorogenic acid (7-10%), is not susceptible to pests and climate, is generally grown at a lower altitude, and bears a lot of fruit and is very fast. The fruit is round.
Currently the largest grower of Robusta is Vietnam, which is also produced in Africa and India.
The more common treatment methods are: sunning, washing, honey treatment and barrel fermentation, which has been popular for more than a year.
Sun exposure: Coffee beans are rich in fruit, sweet aftertaste and high mellowness.
Washed: Coffee beans with a fruity or floral aroma, moderate acidity, low alcohol.
Honey treatment: The coffee beans have a sweeter aftertaste, a delicate fruit aroma and a high mellowness.
Barrel fermentation: coffee beans, and the corresponding aroma has a certain connection, such as brandy, whiskey, etc., moderate alcohol, low acidity.
The treatment method is related to the local natural conditions, if the local sunshine is abundant, the water shortage sun treatment method will be more, on the contrary, the washing treatment method is more.
The purpose of coffee bean grading is to provide a rough benchmark for transactions. There is currently no world-wide method for grading coffee beans. The name and basis of the classification are actually determined by each country of origin.
Identification criteria: Take 300g of green beans and screen through a metal screen with different hole sizes to screen. The basic unit is 1/64 inch, called "mesh", and the net used to screen coffee beans is between 8–20 mesh, that is, 8/64–20/64 inches (about equal to 3–8 mm), and the smaller the number, the larger the hole. Usually less than 14 purposes, there is no chance to become a boutique. In the process of screening, of course, there will be fish that slip through the net, and the tolerance value of the error depends on the standard used.
Let's talk about the grading method of coffee beans commonly found on the market
Ethiopian grading begins with G, a total of 5 + 1 classification system is the most common (Z is the new number of new grades that have just appeared in recent years), the smaller the better, mainly look at the defect rate, based on "the number of defective beans per 300 grams of raw beans, can be allowed" as the benchmark, listed as follows:
Colombia is distinguished by the size of the bean grain, Excelso, Supremo are considered to be large beans, but the latter is a little larger than the former. Colombia is often used as an example: compared to the size of the bean grain, it would be helpful to know the quality if the origin of the region could be known.
Starting from highest to lowest, they are Stictly Soft, Soft, Softish, Hard, Riada, Rio, Rio Zona, hard, including lower grades, which are considered commercial beans.
Brazil is one of the world's top coffee producers, from cheap instant coffee to premium grade estate beans. Due to its natural environment, Brazil's coffee grows at a lower height than its neighbors, at an altitude of about 600–1200 meters, so it has developed its own ranking. Soft in the name does not refer to the softness and hardness of the beans, but to the mild and supple performance of the flavor.
Think the same, and so on. In fact, the growth height referred to is not the same from country to country. In Ecuador, for example, the SHG is over 1300 meters and the HG is 1220–1300 meters; in Honduras, the SHG is over 1200 meters and the HG is 1000–1200 meters.
Kenyan beans are loved by many people, not only because they are delicious, but also because they are "so big"! Usually Kenyan beans, divided into 9 grades
Commonly seen AA+, AA++, AA Top, AB+, are traders' own ratings, not in the official Kenyan system. Different traders have different definitions, so please refer to it.
Nowadays, many friends mostly buy coffee beans online or in physical stores. However, you can only see the product introduction or the packaging of the coffee, so how to understand the packaging of coffee has become an important condition for choosing coffee. Here's how to teach you how to read coffee packaging.
Let's take a specialty coffee bean as an example:

In addition, at present, when buying coffee beans online, many professional stores generally contain several contents in the information of coffee
1. The degree of roasting of coffee beans
2. Cupping information of coffee
Through professional coffee testing, you can get a very metaphysical coffee experience such as flavor information, aroma, texture, acidity, and afterglow of coffee.
Coffee beans can be selected based on the overall description and flavor information.
3. Brewing recommendations
Brewing recommendations give the brewing ratios of several common brewing utensils. If you are a newcomer, you can refer to this parameter for brewing. According to the final result, the parameters are adjusted. Find your favorite flavor.
1. Do not buy ground coffee / Do not grind coffee beans. It is recommended to buy coffee beans and grind them when they are drunk. Ensure the preservation of coffee grease, aroma and flavor.
2. Please buy freshly roasted coffee beans, preferably within 3 days. If the coffee beans are too long, please do not buy them.
3. Do not buy a large number of coffee beans at one time, please buy a small amount frequently to ensure the freshness of coffee beans.
