什麼是圓豆咖啡(PB)?它有什麼特別的?

什麼是圓豆咖啡(PB)

Coffee starts it’s life as a fruit, the coffee cherry. The cherry has fruit (mucilage) on the outside and typically two seeds facing each other in the center (much like other fruits we eat). These two seeds have flat surfaces facing each other, and rounded surfaces facing the rest of the fruit. Peaberry is a genetic deformity when, instead of two seeds, a cherry has just one seed, with no flat surface, just rounded on both sides.

咖啡是一種果實,而咖啡果實的外層有果肉(果膠層),中間通常由兩顆種子面對面組成(就如一般我們所吃的水果一樣),這兩顆種子的平面向內相對,圓面則面向外層果肉。圓豆是一種遺傳性的畸形,果實裡只有一顆而非兩顆種子,而這顆種子沒有平面,兩側都是圓面。




The coffee bean on the right is a peaberry, while the one on the left is a regular coffee bean. Notice how the peaberry is rounded on all sides while the regular bean has one flat side. 

上圖兩顆咖啡豆的右側是圓豆,左側則是正常的咖啡豆,可以看到圓豆每一側都是圓形,而正常咖啡豆有一側是平面。






Why do they exist?
為什麼會有圓豆?
Nobody knows this for sure. There hasn’t been enough scientific study done to understand peaberries. 5-10% of all cherries are peaberries!
沒有人能確定,至今也沒有足夠科學研究說明圓豆的由來,而咖啡果實中的種子有5-10%是圓豆。




How are peaberry seeds sorted?
如何篩選出圓豆?
You could find peaberry seeds in any coffee, and they can be found in any coffee growing country. Coffee that’s called “Peaberry” indicates that the peaberries have been manually hand-picked from lots during coffee processing.
每一種咖啡裡面都可能找到圓豆,也可以在任何咖啡產國找到。咖啡圓豆是由於在咖啡處理過程,完全是手挑作業才能區別與篩選這些圓豆。

Peaberry coffees are usually found in countries like Tanzania, Kenya & Brazil since these countries have the infrastructure setup to sort the peaberries.
圓豆常會在坦尚尼亞、肯亞與巴西出現,因為這些國家有設置專門篩選圓豆的建設。



What’s special about the taste?
圓豆喝起來有什麼特別?
 This is a debatable topic – some claim that it produces a more flavorful cup, slightly brighter & light-bodied cup compared to the same lot with normal berries. However, this hasn’t been consistently proven. You can brew a peaberry coffee just like you normally would brew any other coffee. And as you drink that delicious cup, definitely appreciate the extra work that has gone into picking these special beans!
關於這部分具有爭議,一些人認為圓豆風味更佳,相較同樣批次的正常豆,圓豆的風味稍微明亮而醇厚度較低。然而這一直沒有被證實,沖煮圓豆就像沖煮其他一般的豆子,而當你享用用圓豆沖出來的咖啡時,一定會將咖啡好喝歸因於這些挑選出來的特別豆。
