在精品咖啡的世界中，法式濾壓壺(French Press)與手沖咖啡(Pour Over)是兩種常見的家用萃取方式，兩者雖然都能帶出風味豐富的咖啡，但在萃取原理、風味表現、研磨度與操作手法上各有千秋，也因應不同豆種有不同的應用策略。
In the world of specialty coffee, the French Press and Pour Over are two popular home-brewing methods. Both are capable of bringing out complex flavors from coffee beans, but they differ in their extraction principles, flavor profiles, grind size, and techniques. Depending on the bean type, each method has its own optimal application strategy.
一、萃取原理與風味走向
Extraction Principles and Flavor Profiles
法式濾壓壺屬於全浸泡式萃取工具。將粗研磨的咖啡粉與熱水靜置浸泡，通常4分鐘左右，最後透過金屬濾網壓下粉層，即可倒出咖啡。金屬濾網不會過濾油脂與微粒，因此能保留咖啡的天然油脂與部分懸浮細粉，使得整體口感飽滿、滑順，風味較厚重。
The French Press uses a full-immersion extraction method. Coarsely ground coffee is steeped in hot water for around 4 minutes, separated using a metal mesh plunger, then you can pour out coffee. Since the metal filter doesn't remove oils or fine particles, this method preserves the coffee's natural oils and micro-grounds, resulting in a full-bodied, smooth, and rich flavor.
相對地，手沖咖啡採用滴濾式萃取原理，透過控制水流速度與方向，讓熱水均勻地穿過中研磨的咖啡粉層，經過紙濾後流入下方容器。此過程更強調流速控制與分段注水技巧，能展現更清晰的風味層次，酸甜明亮、尾韻乾淨。
In contrast, the Pour Over method uses a drip-brewing principle. Hot water is poured in a controlled flow over medium-ground coffee in a paper filter, allowing it to pass through the grounds and drip into a lower container. This technique focuses more on flow rate control and pulse pouring, yielding cleaner, brighter flavors with a crisp, sweet finish.
二、法壓與手沖的操作比較
Operation Comparison: French Press vs. Pour Over
三、法壓與虹吸壺的結構比較
French Press vs. Siphon Brewer: Structural Differences
許多人會將法式濾壓壺與虹吸壺（Siphon）歸為同一類型，因為它們都屬於全浸泡式萃取工具。實際上，它們在操作邏輯和萃取動力上存在顯著差異。
Many people group the French Press and Siphon (vacuum pot) together because both use full-immersion brewing. However, they differ significantly in terms of brewing logic and extraction dynamics.
雖然都讓咖啡粉與熱水完整接觸，但虹吸壺因其氣壓驅動的動態對流設計，常被認為結合了浸泡的飽滿與濾滴的乾淨表現。若將三者並列，虹吸壺風味上更趨近於介於法壓的厚重與手沖的清爽之間，適合追求平衡口感與香氣層次的咖啡愛好者。
While both methods fully immerse the coffee grounds, the siphon brewer introduces dynamic convection driven by vapor pressure. It's often seen as combining the richness of immersion with the cleanliness of filtration. In terms of flavor, siphon brews usually sit between the French Press’s heaviness and the Pour Over’s clarity—making it an ideal choice for those seeking balance and complexity in aroma and taste.
四、悶蒸與預處理：相通之處
Blooming and Pre-Processing: Shared Concepts
手沖咖啡中有一個關鍵步驟：「悶蒸（blooming）」，通常在萃取初期注入少量熱水，讓咖啡粉膨脹、釋放二氧化碳並均勻濕潤粉層，促進均一萃取與香氣釋放。
A crucial step in Pour Over brewing is “blooming”—adding a small amount of hot water at the beginning of extraction to allow the coffee to swell, release CO₂, and evenly saturate the grounds. This helps promote even extraction and enhances aroma release.
法壓中雖無正式悶蒸概念，但多會在注水初期進行10～15秒攪拌，目的相同。進階做法可採「兩段式注水」：先注40g靜置，再注滿水並攪拌，這樣能模擬悶蒸效果，展現更清爽、乾淨的風味。
While the French Press doesn't have a formal blooming phase, it often includes a 10–15 second stir shortly after water is added, achieving a similar effect. A more advanced method uses a two-phase pour: first pour 40g of water and let it sit briefly before filling up and stirring. This approach mimics blooming and results in a cleaner, more vibrant cup.
五、衣索比亞水洗淺焙的兩種應用配方
Two Contrasting Recipes Using Ethiopian Washed Light Roast
針對淺焙花香調的衣索比亞水洗豆，我們可設計出兩種極具對比性的配方：
For a floral, light-roasted Ethiopian washed bean, two very different recipes can be crafted:
小編試沖：衣索比亞 谷吉 罕貝拉 布穀阿貝兒 芭絲特處理站 藝妓 G1 水洗
杯測風味：牡丹花 紫羅蘭 葡萄 柑橘糖果 檸檬 尾韻甜柚 口感飽滿滑順
Test Brew: Ethiopia Guji Hambela Buku Abel Baste Station Gesha G1 Washed
Tasting Notes: Peony, violet, grape, citrus candy, lemon, sweet pomelo finish. Mouthfeel: full and smooth.
手沖（乾淨明亮）
20g 粉 / 320g 水，90°C，中偏細研磨
分三段注水，總時間 2:30
呈現乾淨明亮，花香高揚、果酸立體，甜柚般尾韻
Pour Over (Clean and Bright)
20g coffee / 320g water, 90°C, medium-fine grind
Pour in 3 stages, total brew time: 2:30
Flavor: Bright and clean with prominent floral notes and juicy acidity; sweet pomelo-like aftertaste.
法壓（花蜜茶感）
20g 粉 / 320g 水，92°C，粗研磨
注水後靜置4分鐘，攪拌後立即壓出
呈現滑順飽滿、香氣融合，像喝溫熱的花蜜茶感
French Press (Floral Honey Tea Profile)
20g coffee / 320g water, 92°C, coarse grind
Steep for 4 minutes, stir and plunge immediately
Flavor: Smooth, rich body with integrated aromas, reminiscent of warm floral honey tea.
法式濾壓壺、手沖與虹吸壺三者代表了不同的萃取哲學。若你想展現豆子的清香與層次，手沖是理想選擇；若偏好融合感與油脂包覆口感，法壓壺值得嘗試；若追求香氣立體、口感平衡，虹吸壺則兼具藝術與風味，適合進階玩家探索。
The French Press, Pour Over, and Siphon each represent a unique extraction philosophy. For clarity and layered flavors, Pour Over is the ideal choice. For a rich, rounded body with oil-coated mouthfeel, try the French Press. For a balance of aromatic complexity and artistic flair, the Siphon is perfect for adventurous brewers.
