Using the product


How to dilute the product


Alginex must be diluted with water before use, to make a ready for use solution.

Take 1 part Alginex, add 288 parts water and mix thoroughly. The water does not have to be deionised and should be at a temperature of between 5°C and 18°C, preferably between 10°C and 15°C. This ready for use solution can be stored in a closed vessel before use, enabling batches to be made up to cover several rackings over a period of time.


How much of the product to add


Most beers will require an addition of auxiliary finings at a rate between 1ml per 1 litre to 5ml per litre. It is important to note that if auxiliary finings are being used with isinglass, it should be added first before the isinglass.


Where to add auxiliary finings


Auxiliary finings can be added at one of several points:


Into the fermentation vessel


The auxiliary can be added to the fermentation vessel. The addition should be made at the end of fermentation, just as the vessel goes onto chill. The residue fermentation and convection currents on cooling are sufficient to mix the product.


Using auxiliary finings with isinglass


When using auxiliary finings with isinglass, it is important to add it before the isinglass. Otherwise they will not clarify the beer properly. This is because the two products carry opposite charge and will react with each other rather than the hazes on the beer that they are designed to clear.
