Sweet crude,

Definition of Sweet crude:

  1. Crude oil with less than 1 percent by weight of sulfur.

  2. Sweet crude is not only a metaphor for sweet crude as the oil posses a sweet taste. In the nineteenth century, prospectors, or roughnecks, would taste and smell the raw product as it was extracted to judge its relative sulfur content. If the oil tasted vaguely sweet and had a pleasant smell, it was low in sulfur. Sour taste and a smell of rotten eggs indicates a high sulfur content. This is the origin of the terms sweet crude and sour crude.

  3. Sweet crude is a classification of petroleum that contains less than 0.42 percent sulfur, as established by the New York Mercantile Exchange (NYMEX). Sulfur is undesirable in petroleum because it lowers the yield of high-value products including gasoline, diesel fuel, heating oil and jet fuel as well as plastics and other petroleum-derived products.
