Method for producing coffee extract

Abstract

A method for manufacturing a coffee extract is provided which method enables flavor ingredients of coffee to be extracted separately from bitter ingredients. A coffee extract is obtained by a method including a) a step of placing coffee granules in a granule container part substantially sealed by a restraining member, b) a step of guiding an extraction solvent from a first direction into the granule container part for extraction, and c) a step of retrieving, from the first direction, a coffee extract stored in the granule container part.

1 . A method for manufacturing a coffee extract, the method comprising:
 a) a step of placing coffee granules in a granule container part substantially sealed by a restraining member;   b) a step of guiding an extraction solvent from a first direction into the granule container part for extraction; and   c) a step of retrieving, from the first direction, a coffee extract stored in the granule container part.   
     
     
         2 . The method according to  claim 1 , wherein, in step c), the coffee extract is retrieved by guiding water from a second direction opposite to the first direction. 
     
     
         3 . The method according to  claim 1 , wherein, in step c), the coffee extract is retrieved in such a manner that an extraction rate is 20% or less. 
     
     
         4 . The method according to  claim 1 , wherein the restraining member is a mesh member. 
     
     
         5 . The method according to  claim 1 , wherein the coffee granules are accommodated so as to accumulate in such a manner that the coffee granules have a substantially rectangular cross-sectional shape in a direction along an axis. 
     
     
         6 . The method according to  claim 1 , wherein the restraining member is positioned in abutting contact with or in close proximity to a surface of deposited layers of the coffee granules which is opposite to the first direction. 
     
     
         7 . The method according to  claim 1 , wherein the first direction is on a lower side of the deposited layers of the coffee granules. 
     
     
         8 . The method according to  claim 1 , wherein, in step b), the extraction solvent is injected up to a position substantially aligning with a top surface of the deposited layers of coffee granules.
