TTB Updates Regulations and Guidance on Authorized Wine Treating Materials
We have updated the Wine Treating Materials page at TTB.gov to reflect recent changes in TTB regulations. In T.D. TTB-185, published and effective August 24, 2022, we amended our regulations to incorporate materials and processes that had previously been administratively approved, that is, preliminarily approved by TTB pending rulemaking to propose and then finalize changes to the regulations.
We list administratively approved materials and processes at TTB.gov (see Wine Treating Materials). With certain exceptions noted below, we have removed from this list those materials and processes addressed in T.D. TTB-185, which are now contained in TTB regulations.
In the case of certain materials we had previously approved as “yeast nutrients,” or fermentation aids for use in facilitating the fermentation of juice and wine, the regulations have been amended to include these materials at specific usage rates, consistent with those originally proposed for public comment in Notice No. 164.
However, usage rates of “good commercial practice” had previously been administratively approved for these materials, rather than the specific limitations that were ultimately incorporated into the regulations.
As explained in T.D. TTB-185, we intend to propose regulations regarding the usage rates for these materials. In the interim, we will continue to allow, under an administrative approval pending additional rulemaking, the use of biotin, calcium pantothenate, folic acid, inositol, magnesium sulfate, niacin, and pyridoxine hydrochloride at levels consistent with good commercial practice, only for the purpose of providing nutrients to the yeast, rather than to fortify the wine, and thus where the level of any remaining nutrient in the wine is de minimis.
