Abstract:
1. A method of producing a mash extract comprising: a. mixing a first malt enzyme source with an aqueous liquid to obtain an aqueous malt enzyme suspension; b. separately, mixing a second enzyme source with one or more starch-containing adjuncts to obtain a decoction suspension while maintaining temperature conditions that do not cause significant gelatinisation of the starch; c. subjecting the decoction suspension to a first heat treatment of at least 1 minute at 60-85° C. to simultaneously partially gelatinise and enzymatically degrade the starch; d. subjecting the decoction suspension to a second heat treatment of at least 1 minute at 85-120° C. to gelatinise the starch at an increased rate and to a higher extent; e. combining the heated decoction suspension obtained from the second heat treatment with the aqueous malt enzyme suspension from step a. to obtain a mash; f. maintaining the mash at 35-85° C. for at least 20 minutes; and g. separating the heated mash into spent grain and mash extract,
