PROBLEM TO BE SOLVED: To provide a method for producing coffee extraction liquid useful as raw material for a coffee drink having excellent storage stability and also good richness and bitterness while reducing hydroxyhydroquinone.SOLUTION: Provided is a method for producing coffee extraction liquid comprising an extraction process in which the inside of an extraction machine is charged with the following components: (A) first roasted coffee beans having an L value of 14 to 20 (B) second roasted coffee beans having an L value higher than that of the first roasted coffee beans and (C) active carbon in this order from the upstream side in the liquid passing direction, and is fed with an extraction solvent to obtain a coffee extraction liquid. The mass ratio between (A) the first roasted coffee beans and (B) the second roasted coffee beans, [(A)/(B)] is 0.2 to 0.8.SELECTED DRAWING: NoneCOPYRIGHT: (C)2017,JPO&INPIT【課題】ヒドロキシヒドロキノンを低減しつつ、保存安定性に優れ、かつコク及び苦味の良好なコーヒー飲料の原料として有用なコーヒー抽出液の製造方法を提供すること。【解決手段】抽出機内に、通液方向の上流側から次の成分(A)~(C)を、(A)L値が14~20である第1の焙煎コーヒー豆、(B)第1の焙煎コーヒー豆よりもL値の高い第2の焙煎コーヒー豆、及び(C)活性炭の順に仕込み、抽出溶媒を供給してコーヒー抽出液を得る抽出工程を含み、 (A)第1の焙煎コーヒー豆と(B)第2の焙煎コーヒー豆との質量比[(A)/(B)]が0.2~0.8である、コーヒー抽出液の製造方法。【選択図】なし
