Brewing Application sheet
Cost-effective cereal cooking
For high-gelatinizing adjuncts, a separate cooking step during mashing is required to secure sufficient gelatinization and liquefaction. Due to lower stability of malt α-amylases at the gelatinization temperatures of corn, rice and sorghum starch, a liquefaction step that uses only malt enzymes can lead to inconsistent starch degradation. This can result in several process and quality issues such as lower yields, less efficient wort separation and a haze increase in the final product.
BeerCo Alpha Amylase products are heat-stable amylases that offer easy and consistent liquefaction at high temperatures, providing many benefits and preserving full malt enzyme potential for the main mashing process.
● Faster and more consistent liquefaction
● Lower mash viscosity, resulting in easier wort production
● No risk of resistant or retrograded starch formations, or insufficient saccharification
● Reduced processing costs through more efficient liquefaction, increased yield of up to 1%
● Improved flexibility of use of various cereal grain adjuncts
● Reduced energy consumption due to lower temperatures when handling decoction mashes
The amount of Termamyl® added during mashing-in depends on adjunct material and quality.

Rules of Thumb for Dosage Guidance
kg/ton = g/kg
Typical density of enzyme is 1.15 g/ml
Using the above, the 0.15 – 0.25 kg/t recommended dosage becomes 0.13 - 0.22 ml/kg grist
Using higher amounts of adjuncts (>20%) may result in worts with insufficient free amino nitrogen (FAN). This can be counteracted by using a protease such as Neutrase® 0.8 L in the malt mash to extract more nitrogenous compounds from the malt.
BeerCo Alpha Amylase can be deactivated during a typical wort boil.
