Endozym® Alphamyl SB1 is a thermostable α-amylase designed to optimise starch liquefaction in brewing, typically added during mashing. Sourced from Bacillus licheniformis, this enzyme facilitates rapid and consistent starch hydrolysis, enabling higher brewhouse yields, lower viscosity, and increased adjunct use without compromising process flow or beer quality. This makes it a valuable tool for modern breweries pursuing cost efficiency, high gravity brewing, or innovative grist formulations.

How It Works: Enzymatic Starch Breakdown

Alpha-amylases break down large, insoluble polysaccharides (amylose and amylopectin) into soluble dextrins and oligosaccharides by hydrolysing internal α-1,4 glycosidic bonds in starch during mashing. This improved liquefaction enhances mixing, heat transfer, and lautering performance, resulting in smoother wort flow and faster runoff, particularly beneficial in high-adjunct or high-gravity brews. By increasing the conversion of starch to soluble fermentable sugars, the enzyme boosts extract efficiency and brewhouse yield while also shortening mash and lautering times, thereby reducing energy, water usage, and overall processing time.

Technical and Operational Benefits

  • Faster mash conversion and improved wort fluidity

  • Reduced need for malt-derived enzymes, especially with adjunct use

  • Improved brewhouse yield, particularly in large-scale or high-efficiency brews

  • Lower mash viscosity, allowing for smoother lautering and higher wort flow rates

  • Shorter mash and lauter times, improving brewhouse throughput

  • Enhanced starch liquefaction, supporting high-adjunct and high-gravity brewing applications

  • Energy and water savings, due to reduced processing time and improved efficiency

Process Integration

Optimising Dosage: Grain Bill Composition Effect

The amount of unmalted or enzymatically deficient grain strongly influences the required dosage. Unmalted grains lack endogenous α-amylase, so higher dosages of Endozym® Alphamyl SB1 are necessary to compensate.

Expected Outcomes: Extract Yield

These estimates do not represent direct measurements of ENDOZYM Alphamyl SB1 in controlled trials. They are based on expected outcomes drawn from peer-reviewed literature describing the typical impact of thermostable α-amylases on extract yield, starch liquefaction, and wort production in adjunct-rich and all-malt brewing conditions. Results may vary based on brewing conditions
