在品味咖啡時，花香風味常被視為高品質咖啡的重要特徵之一。然而，許多人在準備或品飲時，卻發現無法感受到咖啡中的花香。這種情況可能與咖啡豆選擇、萃取方式、嗅覺敏感度以及品飲環境有關。以下將詳細探討原因，並提供具體解決方案，幫助更好地體驗咖啡中的花香。
When we drink coffee, floral notes are often regarded as a hallmark of high-quality coffee. However, many people find themselves unable to detect these delicate aromas during preparation or tasting. This can be attributed to factors such as the choice of coffee beans, brewing methods, sensory sensitivity, and the tasting environment. Below, we explore these reasons in detail and provide actionable solutions to help you better experience the floral aromas in coffee.
一、無法感受花香風味的可能原因
Why You Might Be Missing Floral Aromas in Coffee
1. 咖啡豆的特性問題 Characteristics of the Coffee Beans
- 豆子的鮮度不夠
咖啡豆中的花香主要來自揮發性芳香分子。當咖啡豆放置過久或保存不當，這些分子會隨著時間揮發，導致香氣減弱。因此，不夠新鮮或陳舊的豆子通常難以表現出細膩的花香。
Lack of Freshness
Floral aromas come from volatile aromatic compounds in coffee beans. If the beans are stale or improperly stored, these compounds dissipate over time, weakening the fragrance. Therefore, stale or less fresh coffee beans typically struggle to exhibit delicate floral aromas.
- 烘焙程度過深
花香通常在淺焙至淺中焙的咖啡中最為突出。如果豆子烘焙得過深，花香會被更強烈的焦糖味、堅果味或烘焙味掩蓋。
Over-Roasting
Floral notes are most prominent in light to light-medium roasts. Over-roasting the beans can overshadow floral aromas with stronger caramel, nutty, or roasted flavors.
- 豆子品質不佳
並非所有咖啡豆都具有明顯的花香風味。例如，某些產區或品種的豆子偏向於表現堅果、巧克力或水果的風味，而非花香。
Low-Quality Beans
Not all coffee beans naturally exhibit floral aromas. For example, beans from certain regions or varieties might lean towards nutty, chocolaty, or fruity profiles rather than floral ones.
2. 萃取過程的影響 Impact of the Brewing Process
- 水溫過高
花香分子對高溫十分敏感。如果沖煮咖啡的水溫過高(例如超過 95°C)，可能會破壞這些分子，導致香氣消散。
High Water Temperature
Floral compounds are sensitive to heat. Using excessively hot water (above 95°C) during brewing can destroy these delicate molecules, diminishing the aroma.
- 研磨度不合適
如果咖啡粉研磨過粗，萃取不足可能無法釋放咖啡豆中的全部風味；反之，過細的研磨則可能導致過度萃取，掩蓋花香特徵。
Incorrect Grind Size
If the grind size is too coarse, under-extraction may prevent the release of the coffee's full flavors. Conversely, overly fine grinds can lead to over-extraction, masking floral characteristics.
- 比例不平衡
咖啡粉與水的比例過高或過低，可能影響萃取效果，導致花香表現不足。例如，過多的水會稀釋風味，過少則可能讓苦味或酸味過於突出。
Imbalanced Coffee-to-Water Ratio
An incorrect coffee-to-water ratio can affect extraction and cause less floral aroma. Too much water dilutes the flavors, while too little may emphasize bitterness or acidity over floral notes.
3. 嗅覺和味覺感知問題 Sensory Perception Challenges
- 嗅覺疲勞
長時間暴露於強烈的氣味(如香水、食物味)可能導致嗅覺敏感度下降，從而難以捕捉到咖啡中的細膩花香。
Olfactory Fatigue
Prolonged exposure to strong odors (e.g., perfume, food aromas) can reduce olfactory sensitivity, therefore temporarily reduce your ability to perceive subtle scents like floral notes.
- 個人體質
部分人對於某些特定香氣的感知天生較弱，特別是較輕柔的花香特徵。
Individual Sensory Differences
Some people are naturally less sensitive to certain aromas, including the lighter, more subtle floral notes in coffee.
- 品飲習慣
缺乏對花香的認知或練習，可能導致在品飲時忽略這些細節。
Tasting Habits
Without prior experience or training, it can be easy to overlook floral nuances in coffee.
4. 品飲環境干擾 Environmental Distractions
- 環境氣味干擾
在香水、食物味或其他強烈氣味的環境中品飲咖啡，可能掩蓋咖啡的自然香氣，讓花香難以被感知。
Environmental Competing Aromas
Drinking coffee in environments with strong competing smells—like perfume, food, or smoke—can mask its natural aromas.
- 分心或不專注
品飲時未能集中注意力於嗅覺和味覺，可能錯失咖啡中的花香風味。
Lack of Focus
Tasting coffee without paying attention to its aromas and flavors may cause you to miss the subtleties, including floral characteristics.
二、改善方法與具體步驟
How to Enhance Floral Aroma Detection in Coffee
1. 選擇合適的咖啡豆 Choose the Right Coffee Beans
- 花香突出的產區與品種
嘗試選購以花香著稱的咖啡豆，如衣索比亞耶加雪菲(Yirgacheffe)、巴拿馬藝妓咖啡(Geisha)或肯亞咖啡豆等。這些產區的咖啡常帶有茉莉花、玫瑰或各種花香般的香氣。
Opt for Floral-Forward Varieties
Try beans known for their floral characteristics, such as Ethiopia Yirgacheffe, Panama Geisha, or Kenya varieties. These often feature jasmine, rose, or chamomile-like aromas.
- 優先選擇淺焙咖啡
花香在淺焙至淺中焙的豆子中更為突出，因此選擇淺焙咖啡豆能更好地展現其香氣特徵。
Go for Light Roasts
Floral notes are most pronounced in light to light-medium roasts. Choose beans roasted to this level for the best chance of experiencing these aromas.
- 購買新鮮豆子
確保豆子是在烘焙後5~7天開始使用、並在保鮮期內飲用完畢，這時期的咖啡豆通常香氣最佳。
Prioritize Freshness
Use beans that are 5–7 days post-roast and consume them within their shelf life to enjoy peak aroma.
2. 調整萃取方式 Adjust Brewing Techniques
- 控制水溫
將沖煮水溫控制在85-94°C之間，以避免高溫破壞花香分子，也避免水溫過低而萃取不足。
Control Water Temperature
Keep the brewing water temperature between 85–94°C to prevent high heat from destroying floral aroma compounds and to avoid under-extraction caused by low temperatures.
- 調整研磨度
根據萃取方法(如手沖、塞風壺)，調整適合的研磨度，讓萃取均勻且恰到好處。
Refine Grind Size
Match the grind size to your brewing method (e.g., pour-over, siphon) to ensure balanced extraction and optimal aroma release.
- 保持正確比例
建議使用1:15至1:16的咖啡粉與水比例，例如20克咖啡粉對300克水，以獲得咖啡風味的平衡。
Use the Right Ratio
A coffee-to-water ratio of 1:15 or 1:16 is recommended (e.g., 20g of coffee to 300g of water) for balanced flavor and aroma.
3. 提升嗅覺和味覺敏感度 Improve Sensory Sensitivity
- 嗅聞實物花香
日常中多聞茉莉花、玫瑰花、洋甘菊等自然花香，提升對這類氣味的辨識能力。
Practice with Real Floral Scents
Familiarize yourself with natural floral aromas like jasmine, rose, and chamomile to enhance your ability to detect similar notes in coffee.
- 專注品味咖啡
喝咖啡時，先嗅聞咖啡香氣，並嘗試捕捉其中的花香特徵，避免急於飲用。
Focus on Tasting
Before sipping, take a moment to smell the coffee and consciously look for floral notes. Avoid rushing through the tasting process.
- 使用風味輪工具
參考咖啡風味輪，幫助你在品飲時對照記錄，逐步建立風味辨識能力。
Use a Flavor Wheel
Refer to a coffee flavor wheel to identify and record specific floral aromas, building your sensory vocabulary over time.
4. 創造理想的品飲環境 Create an Ideal Tasting Environment
- 保持空氣清新
避免有其他氣味干擾，如香水、油煙或強烈食物味，確保嗅覺感官的純淨。
Keep Fresh Air
Ensure the tasting area is free from strong scents like perfume, smoke or strong food smell to maintain a clean olfactory environment.
- 專注於品飲過程
選擇安靜的環境，讓注意力集中於咖啡的嗅覺與味覺層次。
Stay Focused
Choose a quiet, distraction-free setting to concentrate fully on the coffee’s aromatic and flavor profile.
5. 適當休息與重試 Take a Break and Try Again
- 減少嗅覺疲勞
如果長時間無法感知花香，可以聞聞清新氣味(如冷水、自己的手腕)來重置嗅覺。
Reduce Olfactory Fatigue
If you have difficulty detecting floral aromas over an extended period, reset your sense of smell by inhaling a neutral scent, such as cool water or your own wrist.
- 多次嘗試
如果第一次未能感受到花香，嘗試在不同時間或狀態下再次品飲，可能會有新的發現。
Give It Another Try
If you don’t notice floral notes the first time, retry the coffee at a different time or in a different state of mind—you might discover something new.
6. 進階建議 Advanced Tips
- 參加杯測活動
在專業的杯測活動中，與他人對比品飲有助於理解與感受咖啡的花香風味。
Join Cupping Sessions
Participate in professional coffee cupping sessions to compare your experiences with others and refine your ability to detect floral notes.
- 記錄品飲經驗
每次記錄咖啡的風味特徵和萃取參數，幫助你總結哪些條件最適合突出花香。
Keep a Flavor Journal
Record the flavor characteristics and brewing parameters for each coffee to identify what works best for enhancing floral aromas.
- 嘗試單一產區豆
選擇單一產區的咖啡豆，有助於專注於特定風味，讓花香表現更為明顯。
Try Single-Origin Coffees
Focus on single-origin beans to better appreciate distinct flavor profiles, including floral characteristics.
