Abstract
The present invention relates to a mash extract and a continuous method of producing the mash extract by decoction mashing. The method comprises: (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; (c) subjecting the decoction suspension to a first heat treatment at 60-85° C. and then a second heat treatment at a higher temperature; (d) combining the heated decoction suspension from the second heat treatment with the aqueous malt enzyme suspension to obtain a mash; (e) maintaining the mash at 35-85° C. for a time; and (f) removing spent grain from the heated mash to produce a mash extract.
Claims17
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,
- wherein steps (a)-(g) are performed in a continuous fashion and wherein the viscosity of the decoction suspension during the first and the second heat treatment does not exceed 1 Pa·s.
