Malt beer is made from malted grains, water, hops, and yeast. The grains are soaked, dried, mashed, boiled with hops, and fermented with yeast. The flavor can be influenced by ingredients and container. Malt brewing dates back to 3500 BC.
Malt beer is made from malted grains, water, hops, and yeast. Barley, wheat and rye are the most common grains used for malting. Malts are used to aid the fermentation process in beer making. When grains are malted, a sugar is produced which ferments into alcohol.
To make malt beer, the first step is to malt the grain. A grain such as barley is soaked in water for about five days. This forces the seed to germinate. As soon as germination begins, the grains are removed from the water and dried with hot air, usually in an oven. This drying process usually takes place in an oven. The amount of roast affects the darkness of the beer, with the lightest roast producing lightest beer and a stout producing darkest.
Once the grains are dry, a process called mashing begins. The malted grains are sent through a masher which converts them into a sugary substance. Depending on the grain, this malt can taste sweet, nutty, toasty, or even chocolatey. The sugary malt is mixed with hot water to become “wort”.
Subsequently, this wort is boiled and hops are added. Hops are the dried flower cone of the hop plant, also called lupus humble. These small flowers add bitterness to the beer, but not flavor.
After the hops have been boiled, the mixture runs through a machine that separates the liquids and solids. The liquid flows rapidly through a cooling chamber and the yeast is added. This fermentation adds alcohol content and carbonation to the stout. Degrees of cooling chamber along with length of fermentation time produce various types of malt beer such as ales, lagers and stouts.
The flavor of stout is influenced by the quality and type of ingredients. Flavoring can include anything from blueberries and apples to cinnamon and spices that add extra or unique flavors to the beer. Sugar substitutes like molasses can also add a different flavor profile. Even the type of container can change the flavor. Oak barrel beer will taste different than beer stored in metal chambers.
The earliest documented evidence of malt brewing dates back to 3500 BC, but the process likely has its roots even earlier in history. At some times in Egypt, beer was consumed more regularly than water as it had less chance of being contaminated. Many stouts were originally used to make bread, while early drinkable stout was more syrupy than today’s versions.
