Key Differences

Malt is created by soaking grains, usually barley, in water to initiate germination, then drying them to halt the process. This produces enzymes that are crucial in converting the grain's starches into sugars. Wort, on the other hand, is the sweet liquid that results when malt is mixed with water and heated, allowing those enzymes to work, breaking down the starches into fermentable sugars.
While malt serves as the backbone of flavor and color in beer and whiskey, providing the essential enzymes for sugar conversion, wort is essentially the "beer before it becomes beer" a sugar-rich liquid that yeast will ferment to produce alcohol. The quality and type of malt directly affect the wort's flavor, color, and sugar content, which in turn influences the beer's character.
Malt can be found in various forms, such as whole grain, crushed, or malt extract, offering brewers and distillers flexibility in flavor and process. Wort, however, undergoes boiling after extraction, during which hops and other flavorings are added, before cooling and transferring to fermentation vessels.
The process of making malt involves careful control of temperature and humidity to optimize enzyme production. In contrast, producing wort requires precise temperature control during mashing to ensure optimal sugar extraction and conversion.
While malt's diversity (pale, amber, chocolate, etc.) allows for a wide range of beer styles and flavors, the treatment of wort such as boiling time and added ingredients further differentiates the final alcoholic beverage, impacting its clarity, bitterness, and aromatic profile.

Malt

Malt is germinated cereal grain that has been dried in a process known as "malting". The grain is made to germinate by soaking in water and is then halted from germinating further by drying with hot air.Malting grain develops the enzymes (α-amylase, β-amylase) required for modifying the grains' starches into various types of sugar, including monosaccharide glucose, disaccharide maltose, trisaccharide maltotriose, and higher sugars called maltodextrines.

Wort

Wort () is the liquid extracted from the mashing process during the brewing of beer or whisky. Wort contains the sugars, the most important being maltose and maltotriose, that will be fermented by the brewing yeast to produce alcohol.
