REMOVING EXCESS COLOR FROM WHITE WINES
Proprietors of bonded wineries and bonded wine cellars
Purpose. The purpose of this industry circular is to announce
the extension of the experimental study for removing excess color
from white wines, other than vermouth, and the conditions to be met
by winemakers desiring to participate.
Background. Refer to Industry Circular No. 58-20 dated August 19,
1958, and 26 CFR 240.527.
Continuation of Experimental Study. In order for additional
data to be obtained respecting the removal of excess color from white
wines, the experimental study is continued through June 30, 1960,
under the procedure and conditions prescribed herein.
Procedure. Where a proprietor is presently participating in the
experimental study he may continue his participation without further
application; however, he should forward to the assistant regional
commissioner (alcohol and tobacco tax) an attachment for his original
application, supplying the information described in "item 1" below as
to future participation. However, any other proprietor intending to
participate in the experimental study must file with his assistant
regional commissioner, in duplicate, an application for continuing
authority to use activated carbon under 26 CFR 240.527. Such application should contain all of the information required by 26 CFR 240.527
1. Color of the expressed juice before treatment with any
material, such as S0 and carbon.
2. Amount of carbon to be used (specify the number of pounds
per 1,000 gallons) and the length of time it will be in
contact with the juice and/or wine.
3. Approximate temperature of the juice or wine during treatment.
4. Describe or explain any unusual factors of the treatment.
A separate application for each batch of juice or wine to be treated
will not be required.
Samples. During the experimental study, samples of the treated
juice and/or wine will be taken as needed by the Government officer
and submitted to the regional laboratory. The dates on which the
samples were taken and analyzed and the kind of grapes from which
the juice was pressed will be shown in the chemist's and regional office's report. The analysis will include the color, and acid
content of the juice and/or wine. It is important that the sampling
of the juice continue throughout the crushing season in order that
data on the change in color, as the season advances, may be obtained.
Samples of wine before and after the addition of wine spirits
will also be taken and submitted to the regional laboratory. The
report of analysis will show the dates the samples were taken and
analyzed, the color, acids, and alcohol content of such wine.
Conditions. Proprietors participating in this experimental study
shall conform with the following conditions:
1. Nine pounds of activated carbon per 1,000 gallons of wine,
including any activated carbon used in the basic wineproducing material, is the absolute maximum which may be used.
2. Wine treated with activated carbon must have a color of
not less than 0.6 Lovibond in a one-half inch cell; however, if a proprietor can achieve in regular production of
wine a color of less than 0.6 Lovibond scale, without the
use of carbon, such procedure may be properly followed.
3. The 0.6 Lovibond restriction applies whenever carbon is
used on bonded winery premises.
4. The proprietor must keep commercial records which shall
show for each batch of wine or basic wine-producing
material treated with carbon the exact details of such
treatment including the kind of juice, by grape variety,
and the kind of carbon used. The records should show
the complete cellar treatment given the finished wine,
such as the use of SO the amount of carbon used, and
time of contact with the wine.
5. Where wine is treated under this experiment and is later
transferred in bond, a notation will be made on Form 703
by the consignor and in the records of the consignee as
to the quantity of activated carbon used for the treatment
prior to shipment. A second treatment may be made if the
total use of activated carbon does not exceed 9 pounds
per 1,000 gallons of wine, i. e., if 5 pounds of activated
carbon per 1,000 gallons were used in the first treatment,
not more than 4 pounds of activated carbon per 1,000 gallons
could be used in the second treatment.
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).
