 same principles that apply to keeping a must uniform from year

 French and German standards, and, as has been already remarked, 

 many vignerons have prepared musts practically identical with 

 those in sugar and acid. It is now assumed amongst the 

 scientific authorities on wine-making that one function of the 

 acids is to contribute to the formation of those ethers (esters) 

 which constitute the bouquet. 



Hitherto only the average must of the whole of Victoria has 

 been under discussion, but interest also attaches to a comparison 

 of the variations of the average must in diflerent parts of the 

 country. In the following table are given the averages for the 

 diffei'ent districts from the individual determinations in Table V.
