In recent years, beer canning has become the preferred packaging method for breweries of all sizes from large-scale producers to small craft beer makers and even homebrewers. Canning offers numerous benefits, including better preservation, cost efficiency, and eco-friendliness. With aluminum cans being 100% recyclable and lightweight, they provide a sustainable alternative to traditional glass bottles.
But what exactly does the beer canning process involve? What equipment is needed? And how can breweries optimize their packaging while maintaining the best beer quality?

Choosing the Right Beer Can Size: A Brewer’s Essential Guide
What is beer canning?
Canning beer refers to the process of packaging beer into aluminum cans, an increasingly popular choice among breweries. This method not only preserves the quality and taste of the beer but also enhances its portability and convenience for consumers.
The history and evolution of beer canning in the craft beer industry
The practice of canning beer dates back to the 1930s, but it has gained significant traction in recent decades, particularly within the craft beer movement. Traditional glass bottles were once the standard, but many craft breweries have recognized the advantages of cans, leading to a modern renaissance in beer canning techniques and design.
Why are more breweries shifting from bottles to cans?
Breweries are opting for cans due to their benefits. Cans provide better protection from light and oxygen, both of which can spoil the delicate flavors of beer. Additionally, cans are lighter, more portable, and more eco-friendly than glass bottles, making them a practical choice for brewers and consumers alike.
Benefits of Canning Beer vs. Other Packaging Methods
Better preservation: Keeps beer fresh and flavorful for longer
Cans are airtight, preventing exposure to light and oxygen. This keeps the beer fresher for longer periods, retaining its intended flavor profile.
Cost and efficiency: Optimized for storage and transportation
Cans can be stacked more efficiently than bottles, saving valuable storage space both in breweries and during transportation. They are also lighter, which can reduce shipping costs.
Sustainability: Aluminum cans are 100% recyclable and eco-friendly
Aluminum is highly recyclable, and when it comes to sustainability, cans provide a more environmentally friendly option than glass. This helps breweries reduce their carbon footprint and appeal to environmentally conscious consumers.
Convenience: Lightweight, easy to transport, and suitable for various occasions
Cans offer convenience for consumers, making them easier to carry to outdoor events, picnics, and parties, without the worry of breakage associated with glass.
The Beer Canning Process – From Production to Distribution
Preparing beer before canning
Before canning, the beer must undergo final filtration and carbonation to ensure optimal clarity and flavor. This preparatory step is crucial for achieving the desired taste profile in the final product.
Choosing the right can (size, material, interior lining)
The selection of the can is vital; breweries must consider size (usually 12 oz, 16 oz, or 19.2 oz), material (aluminum), and the interior lining, which should be designed to prevent corrosion and maintain the integrity of the beer.
The canning process:
Cleaning and preparing cans
Cans must be thoroughly cleaned and sanitized to eliminate any contaminants. This step is essential for preventing spoilage and ensuring the quality of the beer inside.
Filling cans with beer (pressure & oxygen control considerations)
Critical to this process is managing pressure and minimizing oxygen contact. Breweries often use counter-pressure fillers to maintain carbonation and avoid oxidation, which can spoil the beer.
Sealing the cans – Technology and sealing quality
Cans are sealed using a can seamer, which securely attaches the lid to the can body. The quality of this seal is paramount, as it prevents leaks and contamination.
Labeling and finalizing the product
After sealing, cans are labeled according to regulatory requirements, and any additional branding or information is added to enhance consumer recognition and compliance.
Quality control in the beer canning process
Throughout the canning process, breweries implement stringent quality control measures to ensure that the final product meets taste, safety, and regulatory standards.
Beer Canning Equipment & Technology
Automatic vs. semi-automatic canning machines
Breweries often choose between fully automatic and semi-automatic canning machines based on production volume and budget. Automatic machines streamline the entire process, while semi-automatic options provide flexibility with a lower initial investment.
Key factors to consider when selecting canning equipment
When selecting canning equipment, breweries should consider factors such as production capacity, budget, maintenance needs, and the required level of automation to meet their specific operational goals.
Oxygen control technology in canning
Investing in technology that helps control oxygen exposure during the canning process can significantly extend the shelf life and freshness of the beer. This technology is becoming increasingly important as breweries strive to maintain high quality in their products.
Materials and coatings inside beer cans (preventing chemical reactions)
The interior lining of beer cans is designed to prevent reactions between the aluminum and the beer, which could affect taste. This ensures that the beer's flavor remains untainted and enjoyable for consumers.
Homebrewing and DIY Beer Canning – A Guide for Homebrewers
Essential tools and equipment
Homebrewers looking to can their beer should invest in essential tools, such as a can seamer, bottle washer, and a pressure filler. These tools will help ensure a smooth canning process.
How to maintain beer quality when home canning
Maintaining quality during home canning involves careful sanitation, temperature control, and attention to details like carbonation levels to ensure the final product is as fresh as possible.
Tips to prevent oxidation and preserve flavors
- Use counter-pressure filling methods to reduce oxygen exposure.
- Ensure cans and all equipment are thoroughly cleaned and sanitized before use.
- Keep beer cold during the canning process to minimize oxidation risks.
Trends & Innovations in Beer Canning
The rise of sustainable and recycled packaging materials
As the focus on sustainability grows, many breweries are exploring recycled materials for their cans, which not only helps the environment but also aligns with consumer preferences.
Advances in can printing and labeling technology
Innovations in labeling technology are allowing breweries to create more vibrant and eye-catching designs that stand out on shelves, enhancing marketing potential.
Smart technology applications in supply chain management
The integration of smart technology into the supply chain is helping breweries optimize production schedules, track inventory, and improve overall operational efficiency.
