The use of sodium carbonate to reduce the excess natural acidity in wine is considered as being consistent with good commercial practice within the limitations of section 240.524 and section 240.529 of the Federal Wine Regulations, provided the natural or fixed acids are not reduced below five parts per thousand. Winemakers desiring to use sodium carbonate in the cellar treatment of wine may receive the approval of the Assistant Regional Commissioner, Alcohol and Tobacco Tax, by the filing of appropriate notice pursuant to section 240.530 of the regulations.
