Uden Cologne by Xerjoff First introduced by the Italian niche label Xerjoff in 2009, Uden is a versatile, elegant and enchanting spicy aromatic fragrance that combines tropical citrus and woody floral notes with tantalizing notes of vanilla and rum. The opening is sparkling and fresh with pink grapefruit, lemon and bergamot. Enveloping notes of rosewood and guaiac wood then emerge, enhanced by soft sandalwood and spiced rum.
