1. High Wines

That which is practically the first product of distillation in which the substances congeneric with ethyl alcohol have not been transformed or their properties otherwise partially eliminated so as to convert them into any form of potable spirits, will be marked "high wines."

2. Alcohol

(a) All forms of distilled spirits from which the substances congeneric with ethyl alcohol have been removed for practical purposes altogether, and which have been heretofore marked as "pure, neutral, or cologne spirits," will be marked "alcohol." (b) That product which has been commercially known as "alcohol" from which these congeneric substances have not been removed will be marked "commercial alcohol."

3. Spirits, "as the Case may be."

Those products of distillation in which, by reason of the original material used and the methods of distillation employed, the characteristic substances congeneric with alcohol have been retained, which differentiate them into various forms of potable spirits - such as whisky, brandy, rum and gin - will be marked with the particular name of such potable spirit, as the case may be, without other description and without the addition of any adjective or descriptive word whatsoever; and the name of such particular spirit will be used even although when any of such spirits may be drawn from the receiving cisterns into casks certain congeneric products of distillation have not been changed by ageing or otherwise, so as to bring them to the potable form in which they are ultimately to be placed upon the market, provided such spirits have, before being drawn into the casks, been diluted to potable proof so as to then constitute a crude form of potable spirits.
