If your only quest in making Coors Light is looking for a recipe and ingredients only, I think you will have disappointing results. What you need to focus on is the processes used to make Coors Light. If your serious go out and find a Diatomaceous Earth filter somewhere. Most homebrewers don't have the funds, space, and desire to to filter out protien and yeast to make a lesser tasting beer.

Filtration
Individual diatom cell walls often maintain their shape even in commercially processed filter media, such as this one for swimming poolsThe most common use (68%)[citation needed] of diatomaceous earth is as a filter medium, especially for swimming pools. It has a high porosity, because it is composed of microscopically-small, coffin-like, hollow particles. It is used in chemistry under the brand name Celatom or Celite as a filtration aid, to filter very fine particles that would otherwise pass through or clog filter paper. It is also used to filter water, particularly in the drinking water treatment process and in fish tanks, and other liquids, such as beer and wine. It can also filter syrups and sugar. Other industries such as paper, paints, ceramics, soap and detergents use it as a fulling material.
