Malt
The first step in beer production is malting. Malt contains a variety of carbohydrates, including insoluble cellulose and soluble hemicellulose, dextrin, starch, and sugars. Starch accounts for about 50% to 60% of the weight of malt. In order to harvest starch and convert it into sugars, barley needs to go through a process called malting. The barley is soaked in water and the "germ" part of the seed begins to grow into a terminal bud, i.e., germinate. After germination, the malt is dried to prevent further germination and to increase its flavor and aroma. Depending on the style and needs of the beer, the type and treatment of malt will vary.
Hops
Hops are cone-shaped flowers that add aroma and bitterness to beer. The bitterness of hops balances the sweetness of the maltose, leaving a refreshing aftertaste. Hops can also be used as a preservative due to its antibacterial properties. Although there are many types of hops, they can be roughly divided into three categories: bittering hops, aromatic hops, and double-effect hops. Their uses can be seen from the name. Adding different types of hops at different stages of brewing can create a more complex hop flavor and give the beer a good balance between flavor, aroma and bitterness.
Yeast
Yeast management is key to brewery fermentation efficiency and final beer quality. Key steps to maintaining the vitality and viability of cultured yeast include: correct inoculation and pruning of yeast, yeast propagation from the lab to large-scale inoculation, storage of yeast for reuse, and the use of acid-washing yeast technology to reduce infection. There are two main types of yeast: ale yeast and lager yeast. Top-fermenting yeasts are usually fermented at higher temperatures, producing more intense fruity and estery aromas, while bottom-fermenting yeasts are fermented at lower temperatures, producing a cleaner, lighter flavor.
Malt
The first step in beer production is germination. Fresh barley is first soaked in water and then placed in a so-called germination box for germination. During this stage, enzymes (amylases) necessary for separating starch are produced. After that, the germination process is interrupted by drying (kilning) at the optimal stage. The green malt is carefully kilned at 80 degrees Celsius and has a slightly sweet taste after drying. The maltose is then used to feed yeast and eventually form alcohol.
Grinding
The second step in the brewing process is grinding. The finished malt is ground, similar to milling, to make it more soluble in water. Malt mills produce various grades of ground malt: husks, malt meal, grist, and malt powder (from coarse to fine).
Mashing
The mashing process involves placing the malt grains in hot water. As the malt steeps, the hot water activates enzymes that break down starches and release simple sugars. After steeping, the mixture forms a thick substance that looks like porridge. This process can take anywhere from 30 to 120 minutes, or even longer, depending on the temperature and the type of enzymes. The solids are then separated from the sweet water, which is called wort.
Filtering and boiling
After mashing, the wort needs to be separated from the malt residue. This process is called "filtering". The wort then passes through a filter, which is usually made of malt husks or other materials to ensure effective separation of the malt residue. The resulting wort is poured into a boiling kettle and heated to boiling. The boiling process not only kills potential microorganisms, but also releases bitter substances in hops. Hops are usually added at different stages of the boil to achieve different flavor effects.
Cooling and fermentation
After boiling, the wort is cooled quickly to avoid bacterial contamination and then transferred to the fermentation tank. After that, yeast is added to the cooled wort and the "magic" of brewing begins. Over the next few days, the yeast consumes the sugars in the wort, producing carbon dioxide and alcohol. Fermentation time varies depending on the type of beer, but it usually does not exceed two weeks.
Carbonation and maturation
When the fermentation process is considered complete, the conditioning or maturation process can begin. At this point, the yeast will calm down and absorb some of the unwanted compounds, such as carbon dioxide and ethanol. The yeast will then settle out and be separated from the beer along with other unwanted sediment. Carbonation occurs after the beer has been filtered, but is not required for secondary fermented beers. Carbonation has a significant impact on the taste, flavor, aroma, and appearance of the beer.
Consider your brewing goals
Before deciding which brewing system to invest in, you first need to clarify your brewing goals. Do you intend to brew beer for personal pleasure and enjoyment, or do you aspire to build a commercial brewing business? Clear goals will help you choose the most appropriate system and ensure that your investment and efforts will bring the expected return.
Budget and Space Constraints
Your budget and available space will directly impact the brewing system you choose. First, assess your budget range, as different brewing systems and equipment cost different amounts. Beginners may tend to choose a lower-priced system with fewer equipment requirements, while those with a higher budget may support more complex, high-end brewing equipment. In addition, it is also crucial to consider the space required for brewing equipment, ensuring that you have enough space to accommodate and operate the selected system, while also considering the storage and maintenance of the brewing equipment.
Brewer Experience Level
Your brewing experience and skill level are crucial in choosing the right brewing system. Beginners may prefer an extraction brewing system that is easy to operate and has a low learning curve, while experienced brewers may pursue an all-grain brewing system that allows for greater flavor control and inspires creativity.
