An acquired taste, some people regard the durian as having a pleasantly sweet fragrance, whereas others find the aroma overpowering and unpleasant. The smell evokes reactions from deep appreciation to intense disgust, and has been described variously as rotten onions, turpentine, and raw sewage. The persistence of its odour, which may linger for several days, led certain hotels and public transportation services in Southeast Asia to ban the fruit.
