The Malting Process: Unlocking Flavor and Enzymes
The malting process is where the magic happens. It’s a controlled germination that unlocks the barley’s potential and develops the unique flavors that define malted milk.
Steeping: Awakening the Grain
The initial step involves steeping the barley grains in water for a specific period, typically a few days. This process hydrates the kernels, triggering the germination process. The water is changed regularly to prevent the buildup of unwanted microorganisms and to ensure even hydration.
Germination: Controlled Growth and Enzyme Development
The steeped barley is then spread out in a malting floor or placed in specialized germination drums. Here, the grains are allowed to germinate under carefully controlled conditions, including temperature and humidity. This is a critical stage as the barley begins to sprout, activating enzymes like amylase, which break down starches into sugars. The skilled maltster carefully monitors the process, ensuring optimal enzyme development and preventing excessive growth.
Kilning: Drying and Flavor Development
Once the germination process reaches the desired point, the “green malt” is transferred to a kiln. Kilning involves drying the malted barley with heated air, halting germination and reducing moisture content to a safe level for storage. This stage is crucial for developing the characteristic malty flavor. The temperature and duration of kilning influence the color and flavor profile of the final malted barley. Higher temperatures result in darker malts with more intense flavors.
