apple ash ; and the water sokible ash shall contain not less than

As stated in Bulletin 151 there is more or less general opinion 

 among some of the manufacturers and large handlers of vine- 

 gars that there are on the market spurious cider vinegars which 

 are sold in competition Avith the genuine article. In order to 

 give this matter a test cjuite a large number of samples of vine- 

 gar coming from large manufacturers, chiefly outside of the 

 State, were given extended examination and at the same time 

 quite an extended study was made of what we were reasonably 

 confident were strictly pure, home made cider vinegars. The re- 

 sults were presented in Bulletin 151 of this Station. The con- 

 clusion was reached in the bulletin that while some vinegars 

 were more or less suspicious there was no greater departure 

 from a normal cider vinegar in case of vinegars coming from 

 the large manufacturers than in the case of home produced 

 cider vinegars. 



Again in 1909 one of the large shippers of vinegar into Maine 

 called the attention of the Station to this matter. They stated 

 that there was a large amount of so-called cider vinegar being 

 distributed throughout Maine which was practically acetic acid 

 and boiled cider flavored with acetic ether. They suggested 

 the names of several wholesale houses where this type of vin- 

 egar could be found. Three samples of these vinegars were 

 obtained, apparently from three entirely dififerent sources. These 

 samples were sent, together with a cider vinegar of known 

 l)urity but marked abnormality, to an "expert" in Boston who 

 had gained a large experience through his "over twenty-five 

 }ears examination of many thousands of samples while in- 

 spector for the City, and analyst for the Mass. State Board of 

 Health." These samples were sen, in similar packages and with 

 no distinguishing marks other than our numbers. His report 

 contained the chemical tests and the conclusion that 'T do not 

 find that any one of them conforms to the requirement of being 

 the legitimate product of pure apple juice, or made exclusively 

 from apple cider." The sample of cider vinegar made from 

 cider from hand pressed Milding and Snow apples, by slow 

 fermentation without addition of any kind, by the Director of 

 the Station and carefully transferred without sediment to glass
