Perfumer Marc vom Ende visited Sabine Engelhardt, the information science graduate, at work and drew inspiration from the design centre. Together, and with the aid of catchphrases and mood boards, they slowly approached a common understanding of the terms which were to serve as leitmotifs of the fragrance: luxury, urban and quality of life. A fragrance composer has more than 2500 basic substances to draw on: approximately 400 natural substances, essential oils and extracts and also a range of synthetic substances. For each perfume motto, Marc vom Ende created four or five samples: these only differed from one another by a nuance and each fragrance was captivating in its own way. "The process was nerve-wracking," said Sabine Engelhardt. After all, cultural aspects of buyers are also important.
