其實咖啡豆不只是有酸味和苦味，還有其他的甜味、花果味、堅果味、巧克力味等風味。一般來說，烘焙程度越淺，咖啡豆的酸味月明顯，苦味越輕。烘焙程度越深，咖啡豆的酸味越輕，甚至沒有酸味。反之，苦味越重。不同國家、產區、品種、海拔、土壤、處理方式所帶來風味上都會有所不同。每人口味不同，所以沒有好壞之分，多作嘗試，便可找到屬於自己口味的咖啡。
 

In fact, coffee beans not only have acidity and bitterness, but also other flavors such as sweetness, floral and fruity, nutty and chocolate. Generally speaking, the lighter the roast, the more pronounced the acidity of the coffee beans and the lighter the bitterness. The deeper the roast, the lighter the acidity of the coffee beans, or even no acidity. Conversely, the heavier the bitterness. Different countries, production regions, varieties, altitudes, soils, and processing methods will bring different flavors. Each person has different tastes, so there is no good or bad, so try more and you will find your own taste.
