Where Does Malt Come From? Uncovering Its Origins.

Malt is a critical ingredient used in the production of several popular beverages, including beer, whiskey, and malted milk. But where does it come from? What is it made of? This article aims to uncover the origins of malt and provide an in-depth explanation of its production process and uses.

The Definition of Malt

Before we delve into the origins of malt, it’s essential to understand what it is. Malt is a dried, germinated cereal grain or seed, usually barley, that has been processed in a specific way. Malt is soaked, allowed to germinate and then roasted to stop the germinating process, which converts the starches in the grain to sugars, a process that is called malting. Once the malting process is complete, the grain is dried and milled, and this final product is called malt.

Why is Malt Important?

Now that we know what malt is let’s explore its significance. Malt plays a crucial role in brewing and distilling beverages such as beer, whiskey, and malted milk. It contributes to the flavor, aroma, color, and body of these beverages, making it a vital ingredient in the production process. Additionally, malt contains enzymes that help break down the grain’s starches into fermentable sugars, resulting in the formation of alcohol. Therefore, malt is an essential factor in determining the quality of the finished product.

The Origins of Malt

The history of malt traces back to ancient civilizations such as the Egyptians, Greeks, and Romans. They used malt in their beer production process and believed it to be a food of the gods. The use of malt spread throughout Europe, and by the 8th century, malt was a common ingredient in beer-making across the continent.

Barley: The Primary Grain Used to Make Malt

The most commonly used grain in malt production is barley. The reason for barley being selected as the primary grain used to make malt is that it has the ideal properties required for malt production. Barley is high in enzymes and starch, which is important for the conversion of starch to sugar during the malting process. Additionally, barley has a tough outer husk that protects the grain during the malting process.

The Production Process of Malt

Malting involves a series of steps that convert the starch in the grain to sugar. Here is how the production of malt goes:

  • Soaking: The first step in malt production is soaking the grain in water to initiate germination. This process helps to break down the grain’s proteins and activate enzymes.
  • Germination: Once the grain is soaked, it is spread out in a layer to promote germination. During this step, the grain starts to sprout, which converts the grain’s starch into sugar.
  • Kiln Drying: After the grain has reached a particular stage of germination, it is then roasted in an oven or kiln to stop the germination process. This step also gives the malt its characteristic color, aroma, and flavor.
  • Cleaning and Separating: The last step in the production of malt is cleaning and separating the grain from the rootlets and other debris. The malt is then ready for use in the brewing and distilling process.

Uses of Malt

Malt has several uses in the food and beverage industry. Let’s look at some of the most common applications of malt:

Beer Production

Malt is a critical ingredient in beer production because it provides the sugar necessary for alcohol fermentation. In beer production, different types of malt are used depending on the flavors and colors required in the final product. For instance, dark malts produce darker beers such as stouts and ales, while pale malts are used to produce lighter beers such as lagers.

Whiskey Production

Malt is also an essential ingredient in the production of whiskey. Whiskey makers use malted barley to produce the fermentable sugars necessary for the whiskey-making process. They also use malt to contribute to the aroma, color, and flavor of the final product.

Malt Beverages

Malted beverages such as Horlicks and Ovaltine are popular drinks consumed worldwide. They are made by mixing malt extract with milk, sugar, and other flavors. Malted milk is also used in the bakery industry in the production of biscuits, bread, and cakes.

Malt and Health

Malt is a rich source of vitamins and minerals such as B vitamins, magnesium, and phosphorus. It also contains dietary fiber, which is vital for healthy digestion. However, malt is high in calories and not recommended for people trying to lose weight or those with diabetes. Additionally, malt is not suitable for people with celiac disease, a condition that causes gluten intolerance.

What Are the Different Types of Malt?

As mentioned earlier, different types of malt are used in the production of beer and whiskey. They are classified based on their color, flavor, and usage. Here are some of the most common types of malt:

Type of Malt Color Flavor Usage
Pale Ale Malt Light Subtle, delicate sweetness Used in pale ales and lagers
Munich Malt Amber to Medium Rich, Malty flavor Used in Oktoberfest beers, amber, and dark beers
Crystal Malt Pale to Dark Sweet, caramel flavor Used in Scottish and Irish ales, IPAs and porters
Chocolate Malt Dark Brown to Black Roasty, Nutty flavor Used in stouts and porters

The color and flavor of malt are determined by the roasting duration and temperature. The more extended the roasting time, the darker the malt.


From its ancient origins to its present-day significance, it’s evident that malt is a valuable ingredient in the production of several beverages. Its unique flavor, color, and aroma make it a critical component in beer and whiskey production, while its vitamins and minerals make it a healthful ingredient. Through the malting process, barley, the primary grain used to make malt, is transformed into a versatile product that has different colors and flavors. As we’ve seen in this article, the production process of malt is intricate, and several different types of malt are used in brewing and distilling popular beverages.
