沖泡方式

美式咖啡壺:

1. 先將研磨好的咖啡粉倒在濾紙上
2. 加入少量的熱開水約30
3. 再依正常方式煮咖啡即可。

關於使用咖啡機研磨咖啡豆的細度,喜好濃口感者--建議使用2.5細度;喜好合宜口感者,建議使用3~3.5細度。


虹吸式咖啡壺:
 
1. 待水上升至八分滿時,開始倒入咖啡粉
2. 第一次攪拌約810
3. 約待25秒後再攪拌第二次
4. 再約待30秒後攪拌熄火。
5. 可用濕布來回擦拭下座(夏天可用冰水濕布),使上座咖啡加速降至下座,然後倒入預洗溫       熱過的咖啡杯。 

 * 清洗方法:使用完畢後請立即清洗以免殘留,以清水清洗即可。
 *注意事項:
  1.下座一定要擦乾後才可點火,以免爆裂。
  2.切勿將咖啡粉直接放入上座以免咖啡粉浸濕。
  3.切勿將上座插入滾沸的下座,以免熱水噴出,可在下座水尚未滾開前,先將上座側放             不置入。


滴漏式咖啡手沖:


1. 先將濾紙浸溼
2. 將咖啡粉倒入濾杯後鋪平
3. 手沖壺對準濾杯手把以細水柱注入悶蒸
4. 開始第一次注水,採注水字繞法注水,水上至濾杯中間停止注水約停5秒後開始注水。 5. 第二次注水一樣採字繞水注慢慢加大到停水處停水,等到手沖壺內水滴完後,即完成一杯香醇咖啡。


咖啡英文生字

Animal-likeThis odour descriptor is somewhat reminiscent of the smell of animals.  It is not a fragrant aroma like musk but has the characteristic odour of wet fur, sweat, leather, hides or urine.  It is not necessarily considered as a negative attribute but is generally used to describe strong notes.
Ashy
This odour descriptor is similar to that of an ashtray, the odour of smokers' fingers or the smell one gets when cleaning out a fireplace.  It is not used as a negative attribute.  Generally speaking this descriptor is used by the tasters to indicate the degree of roast.
Burnt/Smokey
This odour and flavour descriptor is similar to that found in burnt food.  The odour is associated with smoke produced when burning wood.  This descriptor is frequently used to indicate the degree of roast commonly found by tasters in dark-roasted or oven-roasted coffees.
Chemical/Medicinal
This odour descriptor is reminiscent of chemicals, medicines and the smell of hospitals.  This term is used to describe coffees having aromas such as rio flavour, chemical residues or highly aromatic coffees which produce large amounts of volatiles.
Chocolate-like
This aroma descriptor is reminiscent of the aroma and flavour of cocoa powder and chocolate (including dark chocolate and milk chocolate).  It is an aroma that is sometimes referred to as sweet.
Caramel
This aroma descriptor is reminiscent of the odour and flavour produced when caramelizing sugar without burning it.  Tasters should be cautioned not to use this attribute to describe a burning note.
Cereal/Malty/Toast-like
This descriptor includes aromas characteristic of cereal, malt and toast.  It includes scents such as the aroma and flavour of uncooked or roasted grain (including roasted corn, barley or wheat), malt extract and the aroma and flavour of freshly baked bread and freshly made toast.  This descriptor has a common denominator, a grain-type aroma.  The aromas in this descriptor were grouped together since tasters used these terms interchangeably when evaluating standards of each one.
EarthyThe characteristic odour of fresh earth, wet soil or humus.  Sometimes associated with moulds and reminiscent of raw potato flavour, considered as an undesirable flavour when perceived in coffee.
FloralThis aroma descriptor is similar to the fragrance of flowers.  It is associated with the slight scent of different types of flowers including honeysuckle, jasmine, dandelion and nettles.  It is mainly found when an intense fruity or green aroma is perceived but rarely found having a high intensity by itself.
Fruity/Citrus
This aroma is reminiscent of the odour and taste of fruit.  The natural aroma of berries is highly associated with this attribute.  The perception of high acidity in some coffees is correlated with the citrus characteristic.  Tasters should be cautioned not to use this attribute to describe the aroma of unripe or overripe fruit.
Grassy/Green/Herbal
This aroma descriptor includes three terms which are associated with odours reminiscent of a freshly mowed lawn, fresh green grass or herbs, green foliage, green beans or unripe fruit.
NuttyThis aroma is reminiscent of the odour and flavour of fresh nuts (distinct from rancid nuts) and not of bitter almonds.
Rancid/RottenThis aroma descriptor includes two terms which are associated with odours reminiscent of deterioration and oxidation of several products.  Rancid as the main indicator of fat oxidation mainly refers to rancid nuts and rotten is used as an indicator of deteriorated vegetables or non-oily products.  Tasters should be cautioned not to apply these descriptors to coffees that have strong notes but no signs of deterioration.
Rubber-likeThis odour descriptor is characteristic of the smell of hot tyres, rubber bands and rubber stoppers.  It is not considered a negative attribute but has a characteristic strong note highly recognisable in some coffees.
Spicy
This aroma descriptor is typical of the odour of sweet spices such as cloves, cinnamon and allspice.  Tasters are cautioned not to use this term to describe the aroma of savoury spices such as pepper, oregano and Indian spices.
TobaccoThis aroma descriptor is reminiscent of the odour and taste of tobacco but should not be used for burnt tobacco.
WineyThis terms is used to describe the combined sensation of smell, taste and mouthfeel experiences when drinking wine.  It is generally perceived when a strong acidic or fruity note is found.  Tasters should be cautioned not to apply this term to a sour or fermented flavour.
Woody
This aroma descriptor is reminiscent of the smell of dry wood, an oak barrel, dead wood or cardboard paper.
TASTES
AcidityA basic taste characterised by the solution of an organic acid.  A desirable sharp and pleasing taste particularly strong with certain origins as opposed to an over-fermented sour taste.
Bitterness
A primary taste characterised by the solution of caffeine, quinine and certain alkaloids.  This taste is considered desirable up to a certain level and is affected by the degree of roast brewing procedures.
Sweetness
This is a basic taste descriptor characterised by solutions of sucrose or fructose which are commonly associated with sweet aroma descriptors such as fruity, chocolate and caramel.  It is generally used for describing coffees which are free from off-flavours.
SaltinessA primary taste characterised by a solution of sodium chloride or other salts.
Sourness
This basic taste descriptor refers to an excessively sharp, biting and unpleasant flavour (such as vinegar or acetic acid).  It is sometimes associated with the aroma of fermented coffee.  Tasters should be cautious not to confuse this term with acidity which is generally considered a pleasant and desirable taste in coffee.
MOUTHFEEL
BodyThis attribute descriptor is used to describe the physical properties of the beverage.  A strong but pleasant full mouthfeel characteristic as opposed to being thin.
Astringency
This attribute is characteristic of an after-taste sensation consistent  with a dry feeling in the mouth, undesirable in coffee.

咖啡豆成分


1.      蛋白質
蛋白質是卡路里的主要來源,所佔比例並不高。咖啡粉的蛋白質在煮咖啡時,多半不會溶出來,所以攝取到的有限。

2.     
咖啡生豆所含的糖分約8%,烘焙後糖分大部分會轉化成焦糖,使咖啡形成褐色,和丹寧酸互相結合,便會產生甜味。

3.      咖啡因
適量咖啡因會刺激大腦皮質、促進感覺、判斷、記憶,讓心臟機能變得較活躍,血管擴張血液循環增強,並提高新陳代謝功能。咖啡因亦可減輕肌肉疲勞,促進消化液分泌。除此由於它會促進腎臟機能,幫助體內將多餘的鈉離子排出體外,所以在利尿作用下,約2個小時左右,咖啡因便會被排泄掉。且咖啡風味中的苦味,就是咖啡因所造成的。

4.      脂肪
脂肪在咖啡風味上,佔極為重要角色,而其中最主要的大概要算酸性脂肪和揮發性脂肪。所謂的酸性脂肪即脂肪中含有酸,其強弱會因咖啡種類不同而異。揮發性脂肪是咖啡香氣主要來源,它是一種會散發出約四十種芳香物質,極複雜又微妙的東西。
5.      丹寧酸
經提煉後丹寧酸會變成淡黃色粉末,容易融入水中,一經煮沸,它會分解而產生焦梧酸,若沖泡過久會使咖啡的味道變差。

6.      纖維
生豆的纖維烘焙後會炭化,和焦糖互相結便形成咖啡的色調。

7.      礦物質
有石灰、鐵質、磷、炭酸鈉等,但因所佔的比率極少,影響咖啡的品質以及咖啡的風味不大。

咖啡樹


咖啡樹的特質之一是它的果實一年之內可以結果好幾次,另一特點是花和果實(又稱之為櫻桃)在成熟期不同階段同時並存。整個咖啡業的風格被大自然的變化無常所左右。如果果子長的過熟,裡面的豆子就會爛掉。如果不夠熟,採下來的豆子不會自己變熟。所以採豆工人要經常回到同一棵樹數次以尋找成熟的果子--費盡力氣來回數趟也只不過採到2磅青綠咖啡豆,通常一棵樹一年平均產量即為2磅。下次買咖啡時要牢牢記住這點。
  生產低級咖啡豆的咖啡農喜歡使用節省人工的方法採豆子,但如此一來,因為品質不純正,減損了咖啡風味,降低咖啡等級。非洲有些地區採咖啡豆的方法是搖晃咖啡樹,把果實搖落地面,在果實受傷爛掉之前從地上撿起。巴西大部分地區生產次級咖啡,這些地區採咖啡的方法是一次將枝幹上所有葉子、花朵、過熱與青澀果子統統摘下,被如此殘害的咖啡樹需要兩年的時間才能恢復正常。
  咖啡樹開出嬌弱白花是少見的壯觀景象,其香味彷若香橙和茉莉。有時只是一棵樹獨自開花;如年輕的新娘,有時是整個咖啡園白花怒放,望去有如一片白色花海,美麗醉人但花期稍縱即逝。兩三天之內花瓣隨風散去,只留餘香在空氣中多打轉一下。
  沒多久,小小的果子成堆出現,起先是綠色,然後轉成黃色,再變為紅色和絳紅色,當他們幾乎變黑時就可採收了 在牙買加,果子成熟與否蝙蝠最先知道,他們在晚上吸吮咖啡果漿,就是告訴農人果子成熟了,可以開始採收了。橢圓的果子圍繞著枝幹緊密的聚在一起,修長光滑的墨綠色牙狀葉子對生在枝幹兩邊。向陽一面的葉面較硬 背面則較柔軟蒼白,邊緣形成扇狀。枝幹也是從主幹對生出來。
  長青樹通常在苗圃育種,長成樹苗,一年之後才移到咖啡莊園種植,完全遵照富初阿拉伯人種植培養咖啡樹的方法。咖啡樹生長的最初四、五年會不斷向下扎根,向上發育樹幹,並發展枝幹成一傘狀,以便日後結出豐厚果實。

咖啡樹在商業上主要有三種品種,這三種品種之下又各自有不同分類。阿拉比卡種(arabica)咖啡是最重要,且品質最好的咖啡豆,源自依索匹亞,是目前最被廣泛種植的咖啡。力柏瑞塔種咖啡(liberica)源自賴比瑞亞 諾巴司塔(robusta)源自剛果。後者的名字顯示它粗壯,能夠抵抗惡劣氣候,抗拒疾病侵害;整地、除草、剪枝時不需大多人工照顧,可以任其在林地野外生長。雖然味道比阿拉比卡苦澀,品質也比阿拉比卡遜色甚多。大部分非洲人都是喝諾巴司塔咖啡。因為產量大,所以用來製造即溶咖啡。阿拉比卡咖啡適於生長在海拔2000~6500英尺的高山--海拔愈高,品質愈好;力柏瑞塔和諾巴司塔則最好種植在海拔2000英尺以下。

咖啡樹只能生長在熱帶和亞熱帶地區,咖啡樹在”咖啡帶”範圍內的不同氣候、土壤、海拔高度、降雨量中部能生長。在非洲高溫潮濕的峽谷和森林雨林,咖啡樹長得欣欣向榮;在低溫多霧多風的中美洲它依然結出高品質的咖啡豆;在氣候多變,一會兒旱災,一會兒狂風豪雨的加勒比海區,它仍然開花結果。這些因素就是咖啡豆有不同風味,種類繁多的秘密。

理想的生長環境是溫度在華氏65度與75度之間,適當的海拔高度和年雨量(年雨量在40到120吋之間)。降雨的時間非常重要,成熟期間最好大雨和強烈陽光間歇出現,採收時則需要一段乾旱的天氣。任何形式的土壤都適合,但最好的土壤是分解的火山土、腐植土和透氣滲透性土壤的混合。

一天當中日照時間不用很長,幾小時就夠了。山坡地是理想地點,因為山坡地目照時間短,而且排水良好。咖啡樹下喜歡根部潮濕,高大多葉的樹間植在咖啡園中,一方面擋風,一方面遮陰。

至於咖啡樹的災害方面,霜害和樹葉疾病是最常見的殺手。

咖啡英文"COFFEE"名稱的由來


'咖啡'這詞,於阿拉伯國家的意思是'友善',自從人類發現咖啡豆的用途,咖啡對人日常生活的影響已超越國家、種族外的層面,如今除了茶,咖啡已是世界性最普及的飲料,不再局限古老的藥用傳說,成為現代文明一部分,更轉形成休閒、有品味的象徵! 各式各樣有個性的咖啡店出現,加上咖啡獨有芳香,整合了人的視、聽及嗅覺等味覺,無形間逐漸擴大人類生活層次,形成一股咖啡新文化!

傳說中咖啡名稱由來說法有很多,比較可信的有以下兩種:

1.     語音時代演變說法:
Coffee係英文,法文為Cafe,意大利文Caffe,荷蘭文Koffie,德文則為Kaffee。發音來自阿拉伯文的Qahwah意即植物飲料,以及土耳其文的kahveh

2.     起源地說法:
衣索比亞(當時為Abyssinia,現為Ethiopia,即埃塞俄比亞)有個村落名為Kaffa,有人認為這就係Coffee的語源。

英文著作中最早出現Coffee的字,是在於1601Sherley's Travel這本書。隨後,1610Sir GeorgeSandy的著作Travels 1627年的Francis Bacon1632Burton所著的Anatomy of Melancholy書中,都分別提到有關coffa這種飲料製作,對大腦同心臟、消化系統有益處。 除此以外,1582Rowwolf'sTravel一書中,Rowwolf醫生兼植物學家曾經到古代Levant(地中海的東部及島嶼群)旅行,當時他叫咖啡為chaube。古時候阿拉伯人稱咖啡豆及咖啡樹為bunn,其飲料被稱為bunchum1587年阿拉伯的古書,Sheik Abd-al-kadir中收錄,當時為於阿拉伯首都的Badgad有間醫院,醫院院長Rhazes曾經記述bunchum是治療胃腸病的良藥。

咖啡豆的分類


咖啡豆的分類

咖啡豆的原分為ArabicaRobustaLiberica大類
可細分為數十品種。咖啡豆會因品種、產地、品牌不同而有各自特性。

1.     Arabica   
原自非洲伊索比亞(埃塞俄比亞),目前的咖啡樹,絕大部份係由也門移植到爪哇島栽培成功的種,Arabica適應力強,橢圓型豆形狀,多於高原裁種,其香味同品質係三種之中最好,但因各地土壤、氣候、天然與人為因素不同而風味各異。而且最好的Arabica種中,咖啡因含量比Robusta種少一倍,Arabica種約佔全球產豆量76%

2.      Robusta    
多於非洲熱帶區域栽種,19世紀開始試種時,發現佢對害蟲抵抗力強,適合種於低窪地區,於是大量栽植,但其品質、風味較Arabica差,味道苦、不酸,香味一般,較適合制成混合咖啡,通常用來沖凍咖啡、即溶咖啡同罐裝咖啡。約佔全球產豆量18%

3.      Liberica
原產於非洲西岸,漸漸傳入東方各地,移植爪哇後在短期間內即大受歡迎,然而有一段時間由於遭到蟲害侵蝕,幾乎被滅種。現仍有利比亞、象牙海岸、安哥拉、印尼等國少量栽種,咖啡豆品質為三種中最差,大部分出口到歐洲,約佔全球產豆量6%
