Perfumery houses are companies that specialize in creating and producing fragrances. They develop unique scents by blending various essential oils, aroma compounds, and other ingredients. These houses often have a team of skilled perfumers, known as noses, who craft signature fragrances for their brand or for other companies. Many perfumery houses have a rich history and a distinct identity, often reflecting cultural influences in their creations. They may offer a range of products, including eau de parfum, cologne, and scented body products. Some well-known perfumery houses include Chanel, Dior, and Guerlain.
