You just have to put the White and Whiskey on different lines, so they don't think you're trying to create a new category. They're regulators for the purpose of collecting taxes foremost, you'd be better off creatively designing your labels to comply with current standards than you would trying to teach them something. Just look at a Stranahans bottle, they had to put Colorado and Whiskey on different lines and they probably got more time and money to argue bout it than you or I.
This is to show how they will confuse White in White whiskey with a category, Light whiskey (excerpt from Rev. Ruling 71-188):
"Consideration must be given to the relationship that whisky described as "White" would have to "light whisky." Light whisky has many of the production characteristics of the whisky presently proposed to be subjected to treatment. Production of "light whisky," although barred from bottling until July 1, 1972, began on January 26, 1968. In order that the merits of the present proposal may be recognized without adversely affecting the production, bottling, and designation of "light whisky," it is held that in view of the substantial lack of color, whisky distilled prior to January 26, 1968, at more than 160 degrees of proof, stored in reused cooperage, and subjected to treatment before bottling with activated carbon within the limits described in 27 CFR 5.23(, may be described as "White" provided the treated product has not more than 0.1 color units Lovibond. Further, the adjective "White" must be separated from the designation "whisky" and must appear in smaller type than that used for the designation "whisky.""
