The ale or beer is allowed to remain in these vessels for a longer or shorter time according to the fancy of the brewer or storehouse-man. It is during this period imbibing oxygen from the atmosphere, and sometimes is allowed to remain there until acidification has distinctly commenced, as indicated by white spots appearing on the surface, and by an increase of temperature. The brewer who adopts this practice, thinks the beer is so much flattened as to prevent its fretting in the vat. It will be found, however, that although the beer, from some little decrease in temperature
