Rev. Rul. 60-334

The use of Promine-D, a soya bean protein material, to clarify and stabilize wine, in amounts not to exceed one and one-half pounds per 1,000 gallons of wine, is considered as being consistent with good commercial practice within the limitations of section 240.524 of the Federal Wine Regulations, provided the amount of water used in the process does not exceed 0.5 percent of the volume of the wine to be treated. Winemakers desiring to use Promine-D in the clarification and stabilization of wine may receive the approval of the Assistant Regional Commissioner, Alcohol and Tobacco Tax, by the filing of appropriate notice pursuant to section 240.1052 of the regulations.
