The Benefits of Stainless Steel Beer Kegs

G4 Kegs | January 30, 2024

Kegs play a vital role in the brewing industry. They are responsible for retaining a beer’s quality and flavor, which is necessary for customer satisfaction. However, there are a variety of keg options out in the market. Producers, taprooms,, bars, and restaurants can use their choice of aluminum, plastic, and stainless steel kegs. Part of running a successful business is choosing the right keg equipment that preserves freshness, stands up to repeated use, and stays within your budget.

Why is stainless steel used in brewing? 

Stainless steel is the go-to material for brewing equipment because it’s food (and liquid)-safe, resists corrosion, is durable, and is easy to clean and sanitize. Stainless steel is also a low-cost element, especially when compared to its longevity.

Reasons why stainless steel is used in brewing: longevity and durability, sustainability, affordability and efficiency, flavor preservation.Longevity and Durability

One of the first questions business owners ask is, “How long does stainless steel last?” Stainless steel kegs are built to last years and can withstand rough treatment, such as frequent handling, transportation, and stacking. They don’t dent or break easily, so there is less need for replacements. Due to their extended life, stainless steel kegs are cost-effective and can save money in the long term, which is essential for companies in any beverage industry.


Because stainless steel barrels are designed for resiliency and can last for a long time, they are a more sustainable option than other materials, which might require continual replacements. They are also a more environmentally friendly option to their disposable and plastic counterparts, which end up in landfills and contribute to greenhouse gasses. In fact, reusable stainless steel kegs can diminish greenhouse gas emissions by 5,000 kg of CO2 comparables each year!

Affordability and Efficiency

Saving on brewery supplies and operational costs is paramount to keeping profits in check. Stainless steel kegs can be seamlessly integrated into modern draft systems, meaning switching to stainless won’t require additional upgrade costs. While stainless steel barrels also come with a fair up-front cost, they are reusable, translating to better ROIs for your business.

Flavor Preservation 

All the benefits of kegs don’t matter if they aren’t going to keep your beverage fresh and flavorful. So, does beer taste good in stainless steel? Absolutely! It tastes exactly how the brewer intended.

The beauty of stainless steel is that it won’t impart off-flavors, keeping your brewed drinks tasting perfect, pour after pour. Plus, because of the keg’s durability and design, there isn’t a risk of light or oxygen exposure which can also impact the final taste of a drink.
