烘焙度造就不同的咖啡風味，解答淺焙咖啡迷思 Roasting Level Contributes to Different Coffee Flavors, Dispelling Myths about Light Roast Coffee
淺焙咖啡以保留咖啡產地風味為特色，呈現清新的口感和複雜的花果香氣。酸感較高，類似水果的清爽風味使其獨樹一幟；淺棕色的外觀，與深焙咖啡形成鮮明對比。這種獨特風味吸引著愈來愈多咖啡愛好者，然而，有一些淺焙咖啡的迷思可能需要澄清：
Light roast coffee is known for preserving the flavor of coffee origins, presenting a fresh taste and complex floral and fruity aromas. With a higher acidity, it stands out with a refreshing fruit-like flavor. Its light brown appearance contrasts sharply with dark roast coffee. This unique flavor attracts an increasing number of coffee enthusiasts. However, there are some myths about light roast coffee that may need clarification:
1. 淺焙咖啡一定口感酸澀？
雖然淺焙咖啡通常會帶有明亮的酸感，但不是一定只有酸澀感。淺焙咖啡同樣可以具有平衡的口感，當咖啡本身帶有足夠多的甜度，並經由烘焙後最大化地保留下來，可展現出豐富的風味層次，例如水果、花香或甜香風味等，在酸甜平衡下，可以帶出淺焙咖啡最大的特色。
1. Is light roast coffee always sour?
Although light roast coffee often has a bright acidity, it doesn't always taste sour. Light roast coffee can also have a balanced flavor profile when the coffee itself has enough sweetness and is maximally retained through roasting. It can showcase rich flavor structures, such as fruitiness, floral notes, or sweetness. Under a balance of acidity and sweetness, light roast coffee can reveal its distinctive characteristics.
2. 淺焙咖啡沒有深焙咖啡的濃郁？
淺焙咖啡和深焙咖啡各有其獨特的風味特點。淺焙咖啡更突顯咖啡豆本身的原始風味，呈現清新的酸質和風味複雜度；相比之下，深焙咖啡可能更重，味道更濃烈，但同時可能掩蓋了豆子的天然風味。好的咖啡豆在淺焙下，具有豐富風味，那份花香與果香的濃郁度，是深焙所無法比擬的；然而大部份的深焙咖啡的確具有較重、較濃郁的口感，但不是花果香的濃郁感，而是帶有焦糖香的濃郁感。
2. Does light roast coffee lack the richness of dark roast coffee?
Light roast coffee and dark roast coffee each have their unique flavor characteristics. Light roast coffee highlights the original flavor of the coffee beans, presenting a fresh acidity and flavor complexity; in contrast, dark roast coffee may be heavier and have a stronger taste but may also mask the natural flavor of the beans. Good coffee beans, when lightly roasted, possess rich flavors, such as floral and fruity notes, that are unmatched by dark roast; however, most dark roast coffees indeed have a heavier, richer taste, not the richness of floral and fruity notes but rather a caramel-like richness.
3. 淺焙咖啡因含量高？
咖啡因主要存在於咖啡豆的生豆階段，而不會因烘焙過程而增減，咖啡因的熔點是235°C~238°C，一般最深焙的咖啡不會到達此溫度。咖啡因含量主要取決於咖啡豆的品種，一般來說阿拉比卡咖啡的咖啡因含量(每克咖啡含約12毫克)也比羅布斯塔咖啡(每克咖啡含約24毫克)低。咖啡因是水溶性，所以萃取咖啡時間越長，會萃取到越多的咖啡因；此外，烘焙越深，咖啡失重越多，深焙咖啡會比淺焙咖啡在相同重量下有比較多數量；因此，在萃取沖煮條件相同下，深焙的咖啡因反而會較多。
3. Does light roast coffee have higher caffeine content?
Caffeine primarily exists in coffee beans during the green bean stage and is not affected by the roasting process. The melting point of caffeine is 235°C~238°C, which generally isn't reached in the darkest roasts. Caffeine content mainly depends on the coffee bean variety. In general, Arabica coffee has a lower caffeine content (about 12 mg per gram of coffee) compared to Robusta coffee (about 24 mg per gram of coffee). Caffeine is soluble in water, so the longer the coffee extraction time, the more caffeine will be extracted. Additionally, darker roasts lose more weight during roasting, resulting in more caffeine per unit weight. Therefore, under the same brewing conditions, dark roast coffee may have more caffeine.

4. 淺焙咖啡不適合做濃縮咖啡？
淺焙咖啡同樣適合做濃縮咖啡，只是比較不容易施作成功。濃縮咖啡要有一層濃郁的油脂crema，具有該支咖啡的風味精華。深焙咖啡經烘焙已將咖啡豆本身的油脂帶出來，經過洽當的濃縮咖啡機萃取後，可以取得crema；但淺焙咖啡相較之下比較沒有油脂感，需要在萃取上想辦法增加萃取率，在洽當的時間下，也是可以獲得那層crema。而且淺焙豆的高酸度和清晰風味在這種製作方式下表現得會更加突出，將產地風味特色放大。
4. Is light roast coffee not suitable for making espresso?
Light roast coffee is also suitable for making espresso, but it's just a bit more challenging to do successfully. Espresso requires a layer of rich oil crema, containing the essence of the coffee's flavor. Dark roast coffee has already brought out the natural oils of the coffee beans through roasting, making it easier to achieve crema after proper extraction; however, light roast coffee, in comparison, may lack the crema and requires methods to increase the extraction rate, but with proper timing, it's still possible to achieve crema. Moreover, the high acidity and clear flavors of light roast beans are more pronounced in this method, amplifying the origin flavor characteristics.

5. 淺焙咖啡比較傷胃？
淺焙咖啡通常有更多的酸感，有些人認為淺焙咖啡較容易引起胃部不適，但這取決於個人的身體狀況。然而最主要是咖啡豆的甜感，如果咖啡豆本質很好、具有豐富的甜感，當酸甜平衡時，反而不會剌激胃部不適。然而這並非對所有人都成立，如果您有胃部不適的問題，除了建議喝淺中焙的咖啡之外，儘量避免空腹喝咖啡，才能好好享受咖啡。
5. Does light roast coffee cause more stomach discomfort?
Light roast coffee typically has more acidity, and some people believe it's more likely to cause stomach discomfort; however, this depends on individual body conditions. The main factor is the sweetness of the coffee beans. If the coffee beans have a good natural sweetness and a balanced acidity, it won't cause discomfort. However, this isn't true for everyone. If you experience stomach discomfort, besides recommending drinking light to medium roast coffee, it's also advisable to avoid drinking coffee on an empty stomach to fully enjoy it.
