MIDGET BREWERY


All the operations of a modern beer-making plant are carried out in a working model eight feet high and covering an area of less than five square feet, recently completed for Birmingham University, England. Call the world's smallest brewery, the miniature establishment will test hops, barley, and yeast, and carry out experiments in brewing research. The model consists of four independent units, capable of producing one gallon of beer apiece from each brew. Brewing conditions in any given plant may be simulated, and it is possible to duplicate any local variety of beer or ale.


From Popular Science Magazine, February 1936. No doubt we are still benefiting from the noble knowledge gleaned from this miniature establishment.

A CURIOUS SURVIVAL



A curious survival of an old-time institution exists in some remote places in England, viz., the official ale-taster. The ale-taster takes an oath to "try, taste, and assize the beer and ale put on sale" in his district "whether the same be wholesome for man's body." The old ale taster's method of "analyzing" beer for the purpose of detecting the addition of sugar to the liquor was rather primitive. Like most men in those times, he wore leather breeches, and, when he went to test the ale for the presence of sugar, a pint of fluid was spilt on a well-cleaned bench, and the taster sat upon it till it dried. if, on rising, the seat of the breeches stuck to the bench, then sugar was present, but if not the beer was pure.

CONDENSED BEER

Novel containers for beer


A process for condensing beer, recently patented in England, is described as follows in the English Mechanic: Beer or stout is taken at any stage of fermentation, though the process is better applied when it is fit for drinking, and evaporated in a vacuum-pan until it becomes a thick, viscous fluid. The alcohol and water of course pass off in vapor, which, in turn, is condensed in a receiver, and the alcohol recovered by redistilling the liquid. This alcohol may be mixed again with the condensed beer. By this process of condensation, the beer is reduced to one-eight or one-twelfth of its original bulk, and as the fermentation is suspended by the heat employed, the condensed mixture will keep in any climate for any length of time. The process of reconverting the mixture into beer is also a simple one, consisting merely in adding the bulk of water originally abstracted, and setting up fermentation again by the use of a small quantity of yeast or other ferment. Within forty-eight hours the beer may be drawn from the tap for use, or bottled in the ordinary way; or, without using any ferment, the beer may be bottled, and charged with carbonic-acid gas.


From The Popular Science Monthly, December, 1875. This doesn't seem like a very good idea, but I supposed it is encouraging that they knew they'd need to save the alcohol.
