Beer is free from Infection as it leaves the sheet filter, and a system for maintaining it in this condition until final bottling is outlined. The chief potential source of infection occurs in the bright beer plant, and results are given of bacteriological tests on various sections of this plant using a quaternary ammonium compound as a sterilizing agent. Results are quoted of observations on the shelf life of samples representative of a year's production in the two bottling stores where the system is operated. These unpasteurized samples are stored at 70° F., and the results obtained are satisfactory for all normal requirements, the tests being confirmed by an absence of complaints in the trade.
