SPECIAL NATURAL WINES
Proprietors of bonded wineries
and bonded wine cellars:
Purpose. The purpose of this industry circular is to clarify the policy with
respect to the removal of special natural wines produced under formulas
approved on Form 698 Supplemental.
Background. It has come to the attention of the Alcohol and Tobacco Tax
Division that in some instances treatment of such wines (or of the wine-producing material) involves the use of activated carbon or other filtering aids and
devices and that samples of the finished product indicate that color and other
characteristics of the wine may have been removed. We have undertaken to
develop further instructions which will satisfy the requirements of Part 240 and
at the same time will permit industry to produce a commercially acceptable
product. It is expected that we will be able to issue further instructions not
later than November 1, 1957.
Instructions. Winemakers will be permitted to remove from their premises
only such special natural wine, other than vermouth, which has been made from
natural wines produced strictly in accordance with the provisions of sections
240.527-240.530 inclusive, and which has been produced in accordance with
subpart S. If the color is less than 1.000 Lovibond in a 1/2 inch cell we will
call on the winemaker to show that he has complied in all respects with the
regulations. It is imperative that the regulations be observed, even though the
color is deeper than 1.000 on the Lovibond scale.
Determination. A reading of 1.000 Lovibond in a 1/2 inch cell is the
equivalent of an absorbance value (Optical Density) of 0.100 using monochromatic light measured at 430 millimicrons in a cell of 1/2 inch thickness.
Proportionately larger or smaller absorbance values will be required in cells
having other dimensions since the color measurement is a direct function of
sample thickness. Instruments not capable of resolving the spectrum into
approximately monochromatic light will give values slightly higher for the
same color intensity.
Inquiries. Inquiries concerning this industry circular should refer to its
number and be addressed to the office of your assistant regional commissioner
(alcohol and tobacco tax).
