The invention relates to a strong aromatic flavoring liquor and a production method thereof, and belongs to the technical field of brewing. In order to solve the technical problem, the invention provides a method for producing the strong aromatic flavoring liquor, which comprises the following steps of: a, fermentation: adding bran husk into distilled grains out of a pit, mixing uniformly, loading into a steamer, distilling to obtain liquor, taking out of the steamer, cooling, adding medium temperature daqu, and putting into the pit for fermentation; b, pit turning over for the first time: opening the pit, taking the distilled grains out, adding high temperature daqu, yellow water and an ecological regulator solution, mixing uniformly, and fermenting in the pit for 10 to 12 months; c, pitturning over for the second time: opening the pit, taking the distilled grains out, adding high temperature daqu, yellow water and an ecological regulator solution, mixing uniformly, and fermenting in the pit for 10 to 12 months; and d, distillation to obtain liquor: opening the pit, taking the distilled grains out, adding bran, mixing uniformly, loading into the streamer for distillation, addingan ecological regulator solution into a bottom pot of a steamer bucket, and jointly distilling to obtain the flavoring liquor.
