Which of the following is NOT a method for clarifying beer?

Clarifying beer involves processes that enhance the visual clarity by removing particles, haze, and other components that can cloud the liquid. Filtration and the use of fining agents are both direct methods aimed at achieving this result.

Filtration physically removes suspended solids, while fining agents, such as gelatin or bentonite, bind with suspended particles, causing them to settle out of the beer. Aging in barrels can also contribute to clarification, as the natural settling of particles can occur over time, along with potential interaction with the barrel that might aid in clarity.

On the other hand, adding artificial color does not serve to clarify beer; rather, it is a method that alters the appearance or flavor profile without addressing any haze or particulate issues. Thus, this choice does not belong in the context of methods intended for clarifying beer.
