Yeast vs. Molasses — What's the Difference?

Yeasts are eukaryotic, single-celled microorganisms classified as members of the fungus kingdom. The first yeast originated hundreds of millions of years ago, and at least 1,500 species are currently recognized.

Molasses () or black treacle (British English) is a viscous substance resulting from refining sugarcane or sugar beets into sugar. Molasses varies by the amount of sugar, method of extraction, and age of plant.

A microscopic fungus consisting of single oval cells that reproduce by budding, and capable of converting sugar into alcohol and carbon dioxide.

A thick syrup produced in refining raw sugar and ranging from light to dark brown in color.

Any of various unicellular fungi of the genus Saccharomyces, especially S. cerevisiae, reproducing asexually by budding or sexually through the production of ascospores and capable of fermenting carbohydrates.

Any of various thick syrups made from juice extracted from the fruits or stalks of certain plants

Any of numerous fungi that exhibit a one-celled growth form and reproduce by budding, including certain candidas that can cause infections in humans.

A thick, sweet syrup drained from sugarcane, especially (North America) the still thicker and sweeter syrup produced by boiling down raw molasses.

Froth consisting of yeast cells together with the carbon dioxide they produce in the process of fermentation, present in or added to fruit juices and other substances in the production of alcoholic beverages.

(US) Any similarly thick and sweet syrup produced by boiling down fruit juices, tree saps, etc., especially concentrated maple syrup.

A powdered or compressed commercial preparation of yeast cells, used chiefly as a leavening agent or as a dietary supplement.

(figurative) Anything considered figuratively sweet, especially sweet words.

An agent of ferment or activity

Plural of molass: whiskey made from molasses.

An often humid, yellowish froth produced by fermenting malt worts, and used to brew beer, leaven bread, and also used in certain medicines.

Synonym of molass: whiskey made from molasses.

A single-celled fungus of a wide variety of taxonomic families.

(geology) molasse

A true yeast or budding yeast in order Saccharomycetales.

(obsolete) molass: becomes drunk from molass.

Candida, a ubiquitous fungus that can cause various kinds of infections in humans.

The thick, brown or dark colored, viscid, uncrystallizable sirup which drains from sugar, in the process of manufacture; any thick, viscid, sweet sirup made from vegetable juice or sap, as of the sorghum or maple. See Treacle.

(figuratively) A frothy foam.

Thick dark syrup produced by boiling down juice from sugar cane; especially during sugar refining

To ferment.

(of something prepared with a yeasted dough) To rise.

To exaggerate.

The foam, or troth (top yeast), or the sediment (bottom yeast), of beer or other in fermentation, which contains the yeast plant or its spores, and under certain conditions produces fermentation in saccharine or farinaceous substances; a preparation used for raising dough for bread or cakes, and making it light and puffy; barm; ferment.

Spume, or foam, of water.

A form of fungus which grows as individual rounded cells, rather than in a mycelium, and reproduces by budding; esp. members of the orders Endomycetales and Moniliales. Some fungi may grow both as a yeast or as a mycelium, depending on the conditions of growth.

A commercial leavening agent containing yeast cells; used to raise the dough in making bread and for fermenting beer or whiskey

Any of various single-celled fungi that reproduce asexually by budding or division
