(a) Ingredient information.

1. (1) For each formula you must list each separate ingredient and the specific quantity used, or a range of quantities used. You may include optional ingredients in a formula if they do not impact the labeling or identity of the finished product.
2. (2) For fermented products containing flavorings you must list for each formula: The name of the flavor; the product number or TTB drawback number and approval date of the flavor; the name and location (city and State) of the flavor manufacturer; the alcohol content of the flavor; and the point of production at which the flavor was added (that is, before, during, or after fermentation).

3. (3) For formulas that include the use of flavors and other nonbeverage ingredients containing alcohol, you must explicitly indicate:

   1. (i) The volume and alcohol content of the beer base;
   2. (ii) The maximum volumes of the flavors and other nonbeverage ingredients containing alcohol to be used;
   3. (iii) The alcoholic strength of the flavors and other nonbeverage ingredients containing alcohol;
   4. (iv) The overall alcohol contribution to the finished product provided by the addition of any flavors or other nonbeverage ingredients containing alcohol. You are not required to list the alcohol contribution of individual flavors and other nonbeverage ingredients containing alcohol. You may state the total alcohol contribution from these ingredients to the finished product; and
   5. (v) The final volume and alcohol content of the finished product.

(e) Additional information. The appropriate TTB officer may at any time require you to file additional information concerning a fermented product, ingredients, or processes, in order to determine whether a formula should be approved or disapproved or whether the approval of a formula should be continued.
