Dear Sir: Answering your favor of recent date in regard to the influence of light on the quality of beer, will aay that our observa tions, extending over the last twenty-five years, have convinced' us beyond a doubt that exposure of beer to light has a very detrimental influence on its quality gen erally, but especially upon the flavor of the beer. Not all beer's are alike susceptible to this influenos of light, pale strong hopped beers of the 'Pilsen1 'character, that1 is, the type that is most favored in America, being especially susceptible, and acquiring, when only exposed for a few miputes to the sunlight, a disagreeable odor. We have tested beers repeatedly inA this direction placing the bottles into direct sunlight, and testing the sam after, one, two, three and five minutes exposure, found that the beer with three and five minutes exposure became undrinkable, on account of the peculiar odor developed. upon beer can be successfully counteracted by the employment of brown or dark colored glass bottles, and such bottles are there fore recommendable. Authorities on the subject of the detrimental influence of light on beer are: C. Lintner, Lehrbuch der Bierbrauerei 1875, S. 343 v " Beck, Zeitschrift fur das gesamte I Brauwesen, 1882, S. 370 V. Huth, Der Bierbrauer 1876, S. 127 'Hey., Allg.Zeitschr.f .Bierbr. u. Malz- fabr., 1878, S. 273 The latest and most ' exhaustive 1 series of experiments on this subject are those by the well known scientist J. Brand, in an article entitled '"Tests on the Pro tection afforded by the beer bottle glass against the influence of light." "Zeit schrift fur das gesamte Brauwesen," 1908, page 333.

"In white and green glass bottles the beer is most affected by the action of the light. M i ! Ill btich bottles re, therefore, absolutely inap propriate and should never be employed 'b brewers."

Berlin) 1710. - "Bottles of strong glass should be selected. They should never be of colorless glass, inasmuch , as through the influence of light the beer will not only take on a disagreeable odor and taste, . but will also become turbid.1 ' (Lintner.)

Tenth Edition, Stuttgart, 1900, pagi 6i0 "The beer in the white glass bottle had taken on disagreeable, 6dor and ta .e and was absblutely undrinkable The beer in the dark bottles did not show this peculiar odor and taste."- (G. Beck.) Translation of Extract from Ztitnhrift Jur das Ctiamtt Bramvtstn, 1SS2- page 37. j "It appears that chemical changes are pro duced in the beer, which attains an exceed ingly unpleasant taste and a disagreeable odor.

"While beer quickly deteriorates when it is exposed to direct sunlight, such deterioration Will eventually take place in diffused light." Extract from Proceedings of the Second International Brewers' Congress held la Chicago, October 19-21,, 1911. i "Beer acted upon by light soon takes up " the very disagreeable so-called 'light taste,' ana also a repulsive, skunk-like odor. Beer so affected is offensive to the palate of most consumers."

Schulze (Allgemeine Zeitschriffc fur Brauerei,-1888, p. 593) finds that dark brown bottles offer the Ibest protection against the rays or tne sun. 'K "It is interesting to note the observation that beer in colorless Dottles exposed to diffused light will undergo a change, precipitating a heavy sediment and taking on a disagreeable bcior and taste."

"In recent years the observation has been made that the rays of sunlight effect a chemical change in beer. For this reason the use of beer bottles blown from colorless glass is diminishing, bottles blown from colored glass being chosen: the amber colored bottles, which, when held, towards the light, show the color of light beer, are particularly to be recommended.
