With the rise of craft beer culture, more and more people are trying to brew their beer. Home brewing not only brings a delicious sense of accomplishment but also allows you to experience the joy of creation and enjoy your handmade beer. The basic process of beer brewing is complicated, but for beginners, as long as they master the basic 양조 장비 and process, they can easily get started. In this guide, we will introduce the basic beer brewing process, the required equipment, and some practical skills in detail to help beginners brew their beer from scratch.
What is home-brewed beer?
Home-brewed beer is made by individuals at home or in a small independent space, using raw materials (such as water, malt, hops, and yeast) and related equipment through a certain brewing process. Compared with commercial brewing, home-brewed beer is usually more personalized and diverse, because the brewer can freely choose and adjust the recipe according to personal taste and preference.
Characteristics of home-brewed beer:
- Personalization: Each home brewer can choose different raw materials and brewing methods according to his or her preferences to create a beer with a unique flavor.
- Experimental: Home-brewers often have more room to try different recipes and processes and conduct various experiments, which makes the process of home-brewed beer full of fun and surprises.
- Tradition and culture: Home-brewed beer has a long history, and many cultures have the tradition of home-brewed beer. The brewing process can also be a way of community activities or family gatherings.
- Learning and sense of achievement: Through home-brewed beer, brewers can understand the process of beer making and increase their understanding of beer science and culture. At the same time, successfully brewing a batch of good beer can bring great satisfaction.
- Affordable: Although the initial investment may be higher, home brewing is usually more cost-effective than commercial beer in the long run, especially when you start to produce in batches.
Basic ingredients for home brewing
- Malt: Mainly provides sugars, usually barley malt, but other grains such as wheat, rye, etc. can also be used. Brewers use starch to form sugars and eventually produce alcohol. Malted barley or malt is the preferred grain for brewers to brew beer, although many other types of malt and non-malted grains are often used.
- Water: Pure water is essential because it makes up more than 85% of beer. The better the water quality, the better the beer. You can also buy bottled spring water in gallon bottles.
- Yeast: Responsible for the fermentation process, converting sugars into alcohol and carbon dioxide. Brewer’s yeast comes in two forms: dry yeast and liquid yeast. Dry yeast is the easiest to use and in most cases requires no additional preparation. Liquid yeast has more varieties, but sometimes a yeast starter is required, depending on the strength (original specific gravity) of the batch.
- Hops: For many craft beer lovers, this is our favorite ingredient. Hops are the key to brewing beer. They give beer flavor and aroma and help keep beer fresher longer. In most brewing situations, some hops are boiled in the wort for 1-1.5 hours, during which time the “alpha acids” are the beer’s primary bittering and preservative agents.
The basic process of home brewing
매싱
Mashing is the most basic step in beer brewing, which converts the starch in the malt into sugar. In the mash tun, the crushed malt is mixed with hot water and kept at a certain temperature (usually between 65-70°C) for a process that usually lasts 60-90 minutes. The enzymes in the mashing process separate the starch into fermentable sugars.
Lauting
After mashing, you will have a thick liquid called “wort”. Next, you need to separate the malt residue from the wort. The malt residue is separated from the wort through a filter, which is called “filter residue”. After that, the malt residue can be further washed with water to remove the sugar.
끓이기 및 호핑
Put the filtered wort into the mash tun for boiling. Boiling not only increases the other in the wort but also concentrates the sugars and adds hops (hops) for flavoring. Hops release bitterness, aroma, and preservative components during the boiling process, which can enhance the flavor of beer.
The boiling time is 60-90 minutes, during which hops are added in stages. Generally speaking, the first hops added usually bring bitterness, while the later hops add more flavor to the beer.
냉각
After the boiling is completed, the wort needs to be quickly cooled to a temperature suitable for yeast fermentation (usually 18-24°C). The cooling process must be fast, otherwise it may cause bacterial growth. Use a cooler to help quick connection.
발효
The cooled wort goes into the fermentation barrel, and then yeast is added. The yeast converts sugars into alcohol and rises, and the whole process usually takes one to two weeks. During the primary fermentation, bubbles will appear in the fermentation barrel, which is a phenomenon of rising release. After fermentation, the alcohol content of the beer is roughly determined.
Boating and Conditioning
After fermentation, the beer will form a solution, and the residual yeast and some cells will settle to the bottom. The beer can then be sterilized in bottles and added with sugars (for secondary fermentation in the bottle). After bottling, the beer needs to be aged at room temperature for 2-4 weeks, during which time the taste will gradually become mellow.
What brewing equipment do beginners need for home brewing?
For beginners, home brewing does not require complex equipment, and many basic equipment can be purchased from home brewing kits or found in ordinary kitchen utensils. Here are the basic equipment you need for home brewing:
Brew Pot
The brew pot is used to boil the wort during the wort-making process. We recommend choosing high-quality products, especially those made of 304 stainless steel. The corrosion resistance and heat damage resistance will prove their value over time and last for many years.
Mash pot
The Mash pot is used to mix and heat malt and water to convert the starch in the malt into sugar. Usually, the capacity of the Mash pot should be larger than your fermentation barrel. It is recommended to choose a capacity of 30-40 liters, which can ensure that there is enough space for the Mash process to avoid failure.
발효 배럴
The fermentation barrel is one of the core tools in the beer brewing process. It is used to hold the saccharified liquid and provide an environment suitable for beer fermentation. Beginners can choose stainless steel or plastic fermentation barrels with a capacity of generally 20-30 liters, which can meet the needs of regular home brewing without mass production.
Evaporator
After boiling, the hot wort needs to be cooled quickly to a temperature suitable for yeast fermentation. The device is usually a copper tube-shaped device that is used to quickly cool the hot liquid by flowing cold water. For beginners, choose a simple barrel cooling system, or use a ready-made cooling device.
온도계
Thermometers are crucial throughout the brewing process, especially during the mashing, boiling, and fermentation stages. Maintaining a stable temperature ensures that each stage of brewing is carried out under optimal conditions. It is recommended to use a digital thermometer for higher accuracy.
Bottles and bottle caps
After brewing, the beer needs to be bottled for maturation. It is very important to clean and disinfect the bottles to ensure that there are no residual microorganisms, otherwise, it will affect the taste and quality of the beer. Bottle caps are tools to close the bottle mouth and keep the beer fresh.
Disinfectant
During the juniper process, disinfection is the key to ensuring the quality of the beer. All tools, equipment, and bottles that come into contact with the beer must be thoroughly disinfected to prevent the growth of miscellaneous bacteria. It is recommended to use non-toxic disinfectants designed specifically for juniper.
Funnels and strainers
During the mashing and boiling process, you may need to use a funnel to pour the liquid into other containers, and a strainer to remove malt particles, etc., to ensure that the final beer is clear.
Home Brewing Tips
Keep your equipment clean and sanitized
This is the most basic and important step. All utensils that come into contact with beer during the fermentation process must be thoroughly cleaned and sanitized. The presence of any mold, yeast, or foreign bacteria may affect the fermentation and final taste of the beer, and even cause the beer to spoil.
Control temperature
Make sure to control the temperature during the mashing process. During the mashing process, different temperatures will affect the conversion efficiency of starch in the malt, usually between 65-70℃ (149-158°F). Different types of yeast have different optimal fermentation temperatures. Make sure to ferment at the right temperature to prevent yeast from producing undesirable byproducts.
Make a yeast starter.
A good way to save money is to make a yeast starter. Yeast will happily reproduce under the right conditions. This means that you can reproduce more yeast cells with one bag of yeast cells. This process is simple and takes less than an hour to set up.
Beer clarification
- Add enzymes to the wort to remove proteins and polyphenols that cause haze.
- Choose the right raw materials. Using high alpha hops to increase bitterness can reduce the haze caused by hops in beer. Hop leaves contain more polyphenols than hop extract. Malts with low polyphenol content do exist but will affect the flavor to some extent.
- Try to use a batch rinse, which can reduce the amount of tannin extracted from the husk.
Summary of Home Brewing for Beginners
For beginners, home brewing is an interesting and creative activity. Before you start, it is essential to choose high-quality raw materials, making sure to use high-quality water, malt, hops, and yeast. At the same time, keep the equipment clean and disinfected to prevent contamination. Mastering the temperature control of mash and fermentation is also very important to obtain the ideal flavor and taste. It is recommended to record each step and result for easy adjustment and improvement. In addition, gradually develop your personal style by experimenting with different recipes and brewing techniques. Don’t forget to observe the fermentation regularly and participate in community exchanges to enrich your home brewing experience. In short, be patient and enthusiastic, and you will reap delicious home brews and a full sense of accomplishment.
