This thesis summarizes a feasibility study focused on filtering American whiskey, matured in new toasted and charred casks, at 25 ºF in order to remove haze which forms when product is diluted from cask strength (62% ABV) to bottling strength (40 – 50% ABV). Chill filtration is a process already implemented in the brown spirits industry in order to guarantee the stability of products at different ethyl alcohol concentrations. The filtration trials and cellulose-pad performance were evaluated in terms of economics, turbidity reduction, test time, throughput, color reduction, and shelf life stability. Those trials with satisfactory overall color and stability …
