The dosing rate for Kerry Biofine is typically between 500 to 2,000 mL per hectoliter (hL) or 425 to 1,700 mL per barrel (BBL) of beer. However, it is important to note that the optimal dose rate may vary depending on the specific beer and desired clarity. To determine the best dose rate, it is advisable to perform a fining trial.
In my experience as a sommelier and brewer, conducting fining trials has been an essential step in achieving the desired clarity and stability of beer. These trials involve adding different doses of fining agents, such as Kerry Biofine, to small samples of beer and evaluating the results. By observing the clarity and sedimentation of the samples, brewers can identify the most effective dose rate for their particular beer.
When using Kerry Biofine, it is crucial to ensure effective mixing with the beer. This can be achieved by adding the solution in a manner that allows for thorough and uniform distribution throughout the beer. Depending on the size of the brewing vessel, this may involve using an appropriate mixing or agitation method.
To provide further clarity, let me break down the dosing rate range:
– The lower end of the range, 500 mL per hL or 425 mL per BBL, is suitable for beers that require minimal fining. These are beers that are already relatively clear and may only require a slight improvement in clarity.
– On the other hand, the higher end of the range, 2,000 mL per hL or 1,700 mL per BBL, is more appropriate for beers that are hazier or have higher levels of suspended solids. These beers may need a more significant dose of Kerry Biofine to achieve desired clarity.
It is important to note that the optimal dose rate may also depend on the specific characteristics of the beer, such as its style, ingredients, and brewing process. Some beers may require a higher dose rate to effectively remove haze-causing compounds, while others may achieve satisfactory results with a lower dose.
The dosing rate for Kerry Biofine typically ranges from 500 to 2,000 mL per hL or 425 to 1,700 mL per BBL of beer. However, it is recommended to perform fining trials to determine the most effective dose rate for a particular beer. The solution should be added in a manner that allows for thorough mixing with the beer, ensuring uniform distribution of the fining agent.
