Take home the essence of Argentina with a fragrance inspired by pampas grasses, the northern desert, or Patagonian lupine blossoms. Fueguia 1833, a perfume lab on ultra-chic Avenida Alvear in Recoleta, creates scents from all-natural ingredients. Only the best-quality plants and spices available at production time make the cut, meaning aromas vary from batch to batch. Each bottle bears an engraved lot number, and large flagons come in handsome handmade boxes. Even better: A Fueguia scent does more than make you irresistible—a portion of all proceeds goes to the NGO Help Argentina, a fund-raising organization that supports environmental, human-rights, and public education charities.
