Kerry Biofine Clear is a purified colloidal solution of silicic acid, (SiO2), in water that has been specifically formulated for the rapid sedimentation of yeast and other haze forming particles in beer. It is Vegan friendly. Its usage can help clarify the beer and give it a brilliant clarity. Beer will get cloudy for several different reasons. However, Kerry Biofine is helpful for clearing up cloudy beer in most situations. It is used religiously by professional brewers, and now Great Fermentations is proud to bring this to you, the homebrewer!

Normally used at a rate of 1/4 teaspoon (3mL) per 5 gallon batch, it can be used at a rate of up to 2 tablespoons (31mL) per 5 gallon batch if desired, or if more is required. Some beers require more, so it is always a good idea to start with a small dosage, and increase after a day or two until desired clarity is reached. Use after fermentation and disperse well throughout the beer, allow to work for a day or two, then rack the beer off the sediment. Enjoy a new level of clarity with Biofine!

Never used Biofine before, recipe called for it. The packaging stated how to dose it and how much. But I wasn't sure when to use. in boil, primary, secondary, etc. I went for secondary and it seemed to work great.
