I have been looking through the TTB chapters and I am curious about something. If one was to do as @bluestar mentions, what would the liquor be classified as according to the TTB definitions?
Based on the class and type designation, would it be a Flavored Brandy with XX% wine added? This is based on the following quote from https://www.ttb.gov/spirits/bam/chapter4.pdf.
"Wine may be added up to 15% by volume of the finished product provided at least 12½% of the wine is derived from the base commodity that corresponds to the labeled flavor of the product. If not, or if the wine addition exceeds 15% by volume of the finished product the classes and/or types and percentages (by volume) of the wine must be stated as part of the class and type designation"
