Abstract: The invention relates to a method for producing a fragrance and/or aroma composition using a composition database that contains recipe vectors and attribute vectors associated with groups of base compositions. According to the inventive method a target attribute vector is defined, an operator effecting the transformation of recipe vectors to attribute vectors in at least one surrounding of the target attribute vector is determined, a target recipe vector is determined under the proviso that it is transformed to the target attribute factor using said operator, and defined substance components are mixed with one another in proportions according to the target recipe vector.
