a^Z On the Preparation of Anther Varnijh, 



this precaution, the laft fpirit of wine that paffes over would 



be rendered impure by more or lefs water. 



In common, corn fpirit has an unplcafant fmell and tafte, 



the primary caufe of which is careicfs management of the fire 



during the firft diflillation as well as during the reftification ; 



as by thefe means, in the firll diflillation in particular, the 



grains readily become burnt, and confequently communicate 



that tafte and fmell to the diftllled liquor. The decompofition 



of the jrelatinous matter of the grain feems alfo to contri- 

 te & 



bute to this defeft. The addition of lixivious falts, chalk, 

 or charcoal, during the redlification, is the bed means to 

 improve fpirits which have been hurt in this manner. 



I am however of opinion, that it is poffible to preferve 

 the corn fpirit in a perfc£l flate during the firft diftillation. 

 The fault generally lies in the fermentation of the wafli being 

 too long continued.- In general, the diftillation is not begun 

 till the fermenting liquor throws up no more bubbles, and 

 fliows itfelf perfe&ly tranfparent under the fcum : but it has 

 been confirmed by fc.veral experiments, that the corn fpirit 

 is obtained ftrongeft, and in the greateft abundance, when 

 the mixture is fubjecled to diftillation in its higheft degree of 

 fermentation. If the fermentation be fuffered to obtain its 

 utmoft term completely, a quantity of vinegar will be formed, 

 ■which not only contributes a great deal to give the liquor an 

 impleafant tafte, but aftuallv occafions a confiderable lofs of 

 the faccharine matter ncccflary for the produftion of fpirit of 

 wine.
