4711 Cologne perfume by Muelhens, Originally named Eau de Cologne when it was created, 4711 was the handiwork of Johann Maria Farina before he sold the rights and licenses to the design house of Muelhens in 1792. 4711 Original Eau de Cologne by Maurer & Wirtz is a Citrus Aromatic fragrance for women and men. The fragrance is described as a refined fruity aroma intended to refresh the senses rather than leaving a strong perfume-filled trail. Opening this fragrance are citrus top notes of lemon, orange and grapefruit combined with bergamot. A hint of floral middle notes of rose and rosemary softens the blend backed up by strong base notes of sandalwood, musk, neroli, and petitgrain.
