Polyvinylpyrrolidone As A Clarifying Agent In Wine Production
Proprietors of bonded wine cellars
and others concerned:
An ATF Ruling regarding the use of polyvinylpyrrolidone (PVP) as a clarifying
agent in the production of wine will appear in the first issue of the ATF Bulletin
which is scheduled for publication in the near future. The ruling will read as
The Bureau of Alcohol, Tobacco and Firearms has been asked
whether polyvinylpyrrolidone (PVP) may be used as a clarifying agent
in the production of wine.
The use of PVP as a clarifying agent in the production of wine
is considered as being consistent with good commercial practice
within the provisions of 26 CFR 240.524. The use of such material
shall be limited so that the residual level of PVP in the finished
wine will not exceed 60 ppm.
Winemakers desiring to use polyvinylpyrrolidone in the treatment of wine may obtain approval of the Regional Director, Bureau of
Alcohol, Tobacco and Firearms by filing a notice pursuant to the
provisions of 26 CFR 240.1052.
At the time Part 240 is next amended, 26 CFR 240.1051 will be revised to reflect
the addition of polyvinylpyrrolidone to the list of materials authorized for the treatment of wine.
Inquiries concerning this circular should refer to its number and be addressed
to your Regional Director, Bureau of Alcohol, Tobacco and Firearms.
