哥倫比亞蔗糖處理低因咖啡（Colombia EA Decaf Washed）採用了特殊的去咖啡因方法，稱為蔗糖處理法或EA處理法（Ethyl Acetate），這種方法利用甘蔗發酵產生的天然乙酸乙酯作為溶劑來萃取咖啡因。
This Colombia Sugar Cane Decaf Coffee(Colombia EA Decaf Washed) uses a special decaffeination method called the Sugar Cane Process or EA Process (Ethyl Acetate). This method uses natural ethyl acetate produced by fermenting sugar cane as a solvent to extract the caffeine.

咖啡豆資訊 / Coffee Bean Information
  • 產地 / Origin：哥倫比亞薇拉省 (Huila / Huila Department)
  • 品種 / Variety：Typica / Bourbon / Caturra
  • 海拔 / Altitude：1300–1800m
  • 等級 / Grade：Excelso
  • 處理方式 / Process：水洗 (Washed)，並使用天然乙酸乙酯 (EA / Ethyl Acetate) 進行去咖啡因處理 (decaffeinated)
  • 風味 香料、莓果、蜂蜜、乾淨。Spice, Berry, Honey, Clean.
  • 烘焙度 ：中深

處理流程 / Processing Steps
此過程利用甘蔗糖蜜的副產品發酵生成的天然乙醇，再與醋酸結合形成乙酸乙酯 (EA)。
This process uses natural ethanol produced by fermenting a by-product of sugar cane molasses, which is then combined with acetic acid to form ethyl acetate (EA).
  1. 預處理 / Pre-treatment：生咖啡豆先以低壓蒸汽蒸煮，使其膨脹軟化並打開毛孔。
    • Green coffee beans are first steamed at low pressure to expand, soften, and open up their pores.
  2. 萃取 / Extraction：將咖啡豆浸泡在水和天然乙酸乙酯的溶液中，EA 會選擇性地與咖啡因分子結合並將其移除。
    • The beans are soaked in a solution of water and natural ethyl acetate; the EA selectively binds with caffeine molecules and removes them.
  3. 移除 / Removal：達到所需的低咖啡因水平（通常去除至少 97% 的咖啡因）後，再次用蒸汽處理咖啡豆，以去除任何殘留的 EA 痕跡。
    • Once the desired low caffeine level is reached (usually at least 97% of the caffeine is removed), the beans are steamed again to eliminate any residual traces of EA.
  4. 乾燥 / Drying：最後將咖啡豆真空乾燥至適當的水分含量（約 11-12%），準備進行烘焙。
    • Finally, the coffee beans are vacuum-dried to the appropriate moisture content (approx. 11-12%), ready for roasting.

風味特色 / Flavor Profile
這種處理法因避免了高溫高壓，能更好地保留咖啡豆的原有風味和甜感。杯測風味描述為：香料、莓果、蜂蜜、乾淨。
Because this process avoids high heat and pressure, it better preserves the original flavor and sweetness of the coffee beans. The cupping notes are described as: Spice, Berry, Honey, Clean.
