<strong>Beerzym</strong><br />
<strong>RAPID</strong><br />
Special enzyme for rapid<br />
taste harmonization during<br />
green beer maturation<br />
Product Description<br />
<strong>Beerzym</strong> <strong>RAPID</strong> is a special enzyme for rapid taste harmonization during green beer maturation. The main enzyme activity<br />
is based on an alpha-acetolactate decarboxylase, in short ALDC (alpha-acetolactate decarboxylase: EC.4.1.1.5).<br />
The enzyme is produced by a genetically modified host strain of the species Bacillus (host), the ALDC coding gene was<br />
transferred by a specially selected donor strain of the species Bacillus (donor).<br />
<strong>Beerzym</strong> <strong>RAPID</strong> is proved for purity and quality by specialized laboratories.<br />
Aim of Treatment<br />
Rapid taste harmonization during green beer ripening by direct conversion of α-acetolactate into acetoin already at fermentation<br />
start and during fermentation.<br />
Product and Effect<br />
<strong>Beerzym</strong> <strong>RAPID</strong> is a liquid, slightly cloudy enzyme suspension. The enzyme is applied in brewing, if ripening times for<br />
taste harmonization of the green beer cannot be kept, or if the capacity of the cylindro-conical fermenters is insufficient.<br />
<strong>Beerzym</strong> <strong>RAPID</strong> is an alpha-acetolactate decarboxylase, active at low temperatures, which is added to the cold wort in<br />
the cylindro-conical fermenter and which already at fermentation onset and during fermentation directly converts αacetolactate<br />
to acetoin and thus prevents the formation of diacetyl. <strong>Beerzym</strong> <strong>RAPID</strong> therefore leads to a quicker taste<br />
harmonization during green beer maturation and the entire maturation period is considerably shortened.<br />
Dosage<br />
The enzyme dosage of <strong>Beerzym</strong> <strong>RAPID</strong> depends on the temperature during application and on the brewing technology.<br />
guide value: 80-100 mL/100 hectolitres cold wort<br />
The enzyme is added as first component into the cylindro-conical fermenter.<br />
Application<br />
Shake <strong>Beerzym</strong> <strong>RAPID</strong> well before use (in the jerrycan, canister, etc.) to evenly distribute enzyme-active suspended<br />
matter which could have settled. Then dilute the homogeneous enzyme suspension with cold water and add to the cylindro-conical<br />
fermenter as first component.<br />
Storage<br />
<strong>Beerzym</strong> <strong>RAPID</strong> keeps its declared activity up to 36 months if stored optimally (0-10 °C/32-50 °F). Higher storage temperatures<br />
result in a shorter shelf life. Temperatures above 25 °C (77 °F) are to be avoided. Reseal opened packagings<br />
tightly and use up as soon as possible.<br />
