Clarex 10ml BrewHQ Packed


BREWERS CLARITY is a product containing a highly specific fungal endopeptidase enzyme. This enzyme only cleaves in haze sensitive polypeptides at the carboxyl end of the amino acid proline.


 Prevents chill haze

 No other beer parameters are affected

 Increases production capacity

 Eliminates the cold stabilisation procedure


Chill haze in beer results from precipitation of complexed polyphenol and proteins during cold storage. This precipitation has been shown to result from hydrogen bonding between polyphenols and the proline rich fraction of particular polypeptides. This haze

develops over time and, initially, is reversible (haze disappears when temperature of beer increases). The chill haze can become permanent as the hydrogen bonding gets stronger.

Brewers Clarity prevents precipitation by hydrolysing the sensitive (haze active) polypeptides. It cleaves specifically the sites where such hydrogen bonding occurs. The specificity of the enzyme ensures that no other beer parameters are affected.


Brewer’s clarity can be used with all kinds of malts and other raw materials. The product is added to cooled wort at the beginning of fermentation.

Rates of Use

Check that the product is within its shelf life before use

Experiment with additions to determine the minimum effective rates

Read the Material Safety Data sheet prior to use

Care should be taken to avoid unnecessary skin contact during handling

The required dose rate is determined by:

-the percentage of barley malt, raw barley and /or wheat of the total grist composition

-the specific gravity (plato) of the wort at the beginning if fermentation;

-the shelf-life required (months).
