軟水硬水 Soft Water and Hard Water

軟水硬水 -水有軟硬之分,是指水中礦物質(鈣、鎂等)的多寡,少則軟、多則硬。一般來說,軟水比較甘甜,而硬水帶點苦澀。以「毫克礦物質/公升水」或ppm來表示水的硬度。

Water can be divided into soft and hard, which refers to the amount of minerals (calcium, magnesium, etc.) in the water. Less minerals is soft water, more is hard. Generally speaking, soft water is sweeter, while hard water is bitter. Water hardness is expressed in "mg of minerals/liter of water" or ppm.

 

而「總溶解物質TDS(Total Dissolve Solids)」是指水中含導電物質的總量,TDS和硬度兩個概念上有部分重合,因為都有涉及水中幾個主要物質鈣、鎂等。

"Total Dissolve Solids (TDS)" refers to the total amount of conductive substances in water. The two concepts of TDS and hardness partially overlap, because they both involve several major substances in water such as calcium and magnesium.

 

如果水中礦物質太多,會導致水沒有足夠的空間留給咖啡的物質,這也是為什麼要用軟水泡茶的原因。

If there are too many minerals in the water, the water will not have enough space for the substances of the coffee, which is also why it is necessary to use soft water to make tea.

 

一般來說,過硬的水質沖煮的咖啡味道易於平淡;這也是為什麼要用軟水泡茶的原因。

In general, coffee brewed with extremely hard water tends to taste bland. This is also why soft water is used to make tea.

 

根據「世界衛生組織」提供之數據,水中鈣、鎂含量在120毫克以下的稱為「軟水」,反之則為「硬水」。

According to the data provided by the "World Health Organization," water with calcium and magnesium content below 120 mg is called "soft water" and vice versa is called "hard water."

 

SCA精品咖啡協會的杯測指南,理想的總溶解物質(TDS)為125-175 ppm,但不應小於100 ppm或大於250 ppm。

The SCA Specialty Coffee Association cupping guidelines ideally have a total dissolved substance (TDS) of 125-175 ppm, but should not be less than 100 ppm or greater than 250 ppm.
