27 CFR §24.54

Every dealer is required to maintain records of transactions. Wine transactions that appear in the records required by subpart O of this part will meet the proprietor's recordkeeping requirements as a dealer. For other transactions not covered in the wine premises records, such as retail sales of distilled spirits or beer in a restaurant at the wine premises, or operations as a wholesale dealer in distilled spirits or beer, the proprietor must keep the records specified for dealers in part 31 of this chapter.
