1. A method for producing a coffee extract which comprises at least 20% total galactose based on the total weight of soluble coffee solids, comprising the steps:
(a) adding water, an endo-β-1,3-galactanase (EC 3.2.1.181), and a β-mannanase to roasted and ground coffee beans, wherein the endo-β-1,3-galactanase is added at a concentration of at least 0.001 g/kg coffee beans and a β-mannanase is added in an amount to produce an increased yield of solubilised coffee solids in the coffee extract which is greater than additive as compared to the increased yield of solubilised coffee solids obtained by incubation with each enzyme alone;
(b) incubating to make an aqueous coffee extract; and
(c) separating the coffee extract from the coffee beans;
wherein the coffee extract comprises at least 20% total galactose, based on the total weight of soluble coffee solids.
