PROBLEM TO BE SOLVED: To provide: a method for manufacturing an extraction liquid which achieves efficient manufacturing a method for manufacturing a coffee with reduced bitterness a method for manufacturing a tea and a method for manufacturing an extraction liquid containing pyrazines.SOLUTION: A method for manufacturing a tea includes extracting an extraction liquid by pouring a processing liquid of 90-150°C onto a barley tea material, 20 wt% or more of which has a grain size of less than 1700 μm, under condition of 0.03 MPa or more, in addition to ambient pressure. A method for manufacturing an extraction liquid containing pyrazines includes extracting an extraction liquid from barley under temperature condition of 100°C or above and under pressurized condition.SELECTED DRAWING: Figure 1COPYRIGHT: (C)2017,JPO&INPIT【課題】効率的に製造可能な抽出液の製造方法、苦みを抑えたコーヒーの製造方法、茶の製造方法及びピラジン類を含む抽出液の製造方法の提供。【解決手段】大気圧に加えて0.03MPa以上の条件下で、麦茶原料の20重量%以上が粒度1700μm未満である麦茶原料に、90~150℃の処理液を注ぎ、抽出液を抽出する、茶の製造方法。100℃以上の温度条件下、加圧条件下で大麦から抽出液を抽出する、ピラジン類を含む抽出液の製造方法。【選択図】図1
