Enzyme preparation which has been developed to increase the complexity of the hop aroma and flavour profile in beer.

The enzyme beta-glucosidase is capable of hydrolysing the glycosidic bonds, liberating monoterpene alcohol compounds and glucose. The glucose is fermented by the yeast while the terpenes (linalool) adds to the aromatic expression of the hops. This process of biotransformation also occurs naturally during a normal fermentation process as yeast secretes some β-glucosidase, although the levels of secreted enzymes are strain-dependent.

Increases the diversity of hop flavors and aroma by changing the ratio of specific terpene compounds
Enhances the beer mouthfeel and drinkability by reducing unpleasant harsh bitterness
Slightly increases wort fermentability
Expresses more character from less sophisticated hop varieties
The recommended dosage is 1 g per 20 liters (5 g / hL) at a temperature between 15 - 65 °C. Dilute the enzyme in an adequate amount (avg. 1:10) of water to allow an even distribution in the fermenting wort.

β-glucosidase activity in biotransformation is a complex process. There are many factors that will have impact on the final product. The selection of the yeast strain, hop variety, timing of hop additions and timing of enzyme addition will all have a direct influence on the final result. Dry-hopping early in fermentation will result in greater extraction of terpene glycosides. Add the enzyme mid-fermentation to allow time for the enzyme to break down glycosides and the actively fermenting yeast to consume the glucose released from the reaction, while minimizing volatile loss from CO2 stripping. It is recommended to perform trials with Aromazyme in order to optimise recipe and process details.

Aromazyme is derived from a selected strain of non-GMO Aspergillus niger.
