Are coffee beans really divided into male and female? No! These are the Chinese common names for coffee flat beans and round beans. Is it true that round beans must taste better than flat beans on the Internet? The front street of this article will take you to understand what is flat beans and what are round beans.
The difference between flat beans and round beans
Coffee beans are the core part of coffee fruit. Under normal circumstances, there are two independent and curved coffee beans in a fruit, which are close to each other and grow together. Such coffee beans are called flat beans, which is the most common shape of coffee beans.
And some fruits will for some reason, there is only one coffee bean growing inside. Without the space occupied by another bean, the coffee bean has more room to grow and eventually becomes a chubby oval. Such coffee beans will be called round beans (Peaberry/PB), also known as beads. The yield of round beans is low, which is common in the branches of young coffee trees, accounting for 510% of the total yield.
What are the reasons for the formation of round beans?
There are many reasons for the formation of round beans, most of which are caused by climate or insect pests. For example, drought in producing areas leads to delayed flowering; small temperature difference between day and night in producing areas leads to rapid fruit growth; pests in the process of fruit growth and other factors will lead to unsound internal development of fruits and the formation of round beans.
Are round beans really better than flat beans?
There are rumors on the Internet that because round beans absorb the nutrients of two beans, so the overall flavor and taste must be better than flat beans, is that really the case? In order to test this claim, Qianjie specially boiled round beans and AA-grade flat beans, which are also from Sassini Manor in Kenya.
Brewing parameters: 15 grams of coffee beans, medium grindability (78% of Chinese standard No. 20 sieve pass rate), water temperature 90 ℃, powder-water ratio 1:15, three-stage circular water injection.
Cooking technique: the first stage is filled with 30g water, then steamed for 30 seconds. Then carry on the section when the water injection is 125 grams, when the water level is about to expose the powder bed, continue to inject water to 225 grams to stop the water injection, and remove the filter cup when the water level is about to be exposed. The extraction of the two beans ended at 2: 39: 03 "±1 second.
Round bean flavor: at high temperature, the taste is berry juice, the acidity of black plum, the sweetness of honey, the full taste of tomato juice after cooling, the acidity of plums and the aftertaste of almonds.
AA flat bean flavor: the taste of tomato juice is full at high temperature, the acidity of black plum and the sweetness of honey, and then slightly nutty, juice-like taste, sour bright.
From the flavor performance after cooking, the two flavors are very similar, in terms of overall hierarchy, adzuki beans win; in terms of overall plumpness, AA flat beans win. Through the comparison of this cooking, Qianjie believes that the overall flavor and taste of round beans must be better than flat beans, depending on whether the drinkers like layers or fullness.
What do we need to pay attention to when baking green beans?
Since round beans tumble faster in the baking bin than flat beans, it is necessary to reduce the speed of the baking bin when baking. At the same time, the density of round beans is higher than that of flat beans, and the heat penetration rate is slower than that of flat beans. Qianjie suggests that coffee beans should be better heated evenly during the development stage by prolonging the dehydration time when roasting round beans.
