The first question is decided by direct testiii:; with a test-still, but as regards the qualitv of tile spirit much depends upon the af,"'. jiiirity, and fineness of the wine employed. White wines are to be preferred, and all'tin- best varieties of 'â cognac" brandy are distilled from tliese wines. A coarser kind of spirit is prepared from the refuse of the wine-press. This refu-c still contains a certain amount of sugar, and fermentation is allowed to take place in \-ats in which the lees are kept at the bottom by means of sieNes. After fennentatir.,, wiiich takes about hve days, the clear liquor is drawn of^' and distilled, producing a spirit of a rough, odour and tiavour. The actual process of distillation is camel out in large stills, a common form of which lonsists of a boiler containing a series of con- centric cylinders so arranged as to effect the separation of the sj^irituous vapours from tin- steam. The boiler is heated by a brick furnace, and the vapours condensed by means ot an ordinary coil condenser, from which the finished sj)int is collected.
