Duties on exports are prohibited in Section 9, Clause 5, of Article I: No tax or duty shall be laid on articles exported from any State.
Taxes are levied, not only upon the liquors themselves, but upon the business of brewing and rectifying; of selling by wholesale and by retail; of manufacturing stills; and upon the stills themselves. A list of these taxes may be obtained from the collector of any internal revenue district.
These were exactly like those imposed by Parliament in the Stamp Act of 1765
