the grapes as they are brought from the vuieyard. The jitice 

 would be received in a vat, where it might be left to fpon-i- 

 taneous ferineutatioii. By this method alone the movement 

 of decompofition would be excrcifed on the whole mafs in 

 an equal manner; the fermentation would be uniform and 

 iiaiuhaneous in regard to all the parts; and the figns which 

 announce, accompany, or folh)w it, would not be difturbed 

 or obfcured by particular movements. The muii^, freed from 

 llie rtalks and huflcs, would no doubt produce wine lefs co- 

 k)ured) more delicate, and more difficult to be prefcrved ; but 

 if the inconveniences of this method exceeded the advantages, 

 k wouM be eafy to prevent them by mixing the exprefled 

 refufc with the muiL 



In confcquence of thefe principles, care oucht to be taken 

 to fill tire vat in twenty-four hours. In Burgundy the vintage 

 is terminated in four or (ive days. Too long time would be 

 attended with the difagrceablc inconvenience of a fucceflive 

 feiies of fermentations, which, on that account alone, would 

 be all imperfecl ; a portion of the mafs would be already fer- 

 mented, while the fermentation would be fcarcely begim in 

 another. The wine thence refulting would then be a real 

 mixture of feveral wines more or lefs fermented. The in- 

 telligent agriculturifi:, therefoie, anxious for the quality of his 

 produces, ought to determine the number of the vintagers ac- 

 cording to the known capacity of his vat; and when unex- 

 pe6led rain makes him fufpend the labour of collecting the 

 grapes, he ought to leave to ferment feparatelv the juice of 

 thofc already colle6led and placed in the vat, rather than run 

 the hazard of expoling himfelf Ibme days after to the danger 

 of interrupting its movements and altering its nature by the 

 addition of frelh and aqueous muft.
