The craft beer industry has exploded in recent years, with over 8,000 craft breweries now operating in the US alone. Craft beer sales have grown at a compound annual growth rate of 10% over the past decade, reaching $29.1 billion in 2021. With this rapid growth, craft breweries are increasingly looking for ways to maintain quality, freshness, and sustainability as they scale up production. This is driving many smaller operations to shift to stainless steel kegs.
For microbreweries dedicated to delivering the highest quality product using premium ingredients, nothing is more important than freshness. The remarkably complex and nuanced aroma profiles, intricate layers of hoppy, malty, and fruity flavors, and smooth, delicate mouthfeel that make craft beers stand out depend entirely on maintaining optimal freshness from the end of the brewing process through packaging, storage, transport, and finally serving in the glass. Stainless steel kegs have emerged as the gold standard container for craft beer, offering superior protection against all the enemies of freshness, and keeping craft beer tasting just as the brewmaster intended for months.
The intricate multi-step brewing process craft brewers use allows them to impart remarkable layers of aroma and flavor into their beer. Fresh, high-quality hops, barley malts, yeast strains, spices, fruits, and other specialty ingredients translate into delightful and complex sensory profiles best enjoyed. At the same time, the beer is still young and at peak liveliness. As the delicate aroma compounds fade over time, and the complex mélange of flavors becomes increasingly muted and dull, the beer slowly loses its essence and vibrancy.
Once packaged, oxygen pickup inevitably occurs every time the container is opened. This leads to oxidative reactions that create stale, cardboard, or metallic flavors that overwhelm the intended profile. Similarly, exposure to light causes the generation of compounds like 3-MBT that impart the classic “skunky” off-notes. Maintaining ideal carbonation and preventing contamination from bacteria and wild yeasts also becomes more and more difficult as time progresses and beer ages past its prime.
With so many remarkable options on the market today, craft beer enthusiasts will simply not tolerate drinking anything less than beer at optimal freshness. The new generation of craft drinkers can distinguish even subtle nuances between flavor profiles, and easily recognize when a once-great beer has aged just a bit too long past its prime. Craft brewers who prioritize keeping their beer as fresh as the day it was packaged will always delight the growing legions of knowledgeable and selective patrons.
Plastic kegs , especially the single-use disposable variety, can easily become scratched and compromised during shipping and use, allowing oxygen and potentially contaminating bacteria to enter and quickly compromise beer quality. Most plastic kegs lack true durability and have a limited life span before needing replacement.
Compounds naturally found in hops and finished beer can leach out aluminum ions into the beer, adversely affecting the flavor and appearance. The protective inner plastic lining or coating has a relatively short lifespan before wearing away, exposing the bare aluminum.
The porous nature of wood makes it nearly impossible to sanitize wooden kegs between fillings fully. Particularly with sour and wild beers, residual yeast strains, bacteria, and other microbes can stubbornly persist in the wood's microscopic crevices and imperfections, ready to potentially cross-contaminate and influence or ruin future batches.
The nonporous, nonreactive stainless steel interior won't degrade or leach any sort of metallic or rubbery flavors during extended storage, allowing the beer to maintain its ideal balanced and delicate aroma and flavor profile for a remarkably long shelf life.
Unlike aluminum containers which can impact pH, bitterness, hop utilization, and character, stainless steel is a blessedly neutral material that does not interfere with or influence the beer's composition.
The impervious, sturdy stainless steel construction is easily sanitized and cleaned even with highly caustic chemicals and high pressure and heat between fills. With proper care, stainless steel kegs can withstand hundreds of use cycles over many years.
With a high recycled content to begin with, stainless steel kegs are infinitely recyclable at the end of life. The reusable nature of steel kegs vastly reduces waste compared to single-use disposable plastic kegs that contribute to landfills and pollution.
Thanks to stainless steel's high thermal conductivity, steel kegs can rapidly chill beer following the hot sterilization process, helping preserve delicate hop aromas. The smooth nonporous interior quickly sheds dirt and deposits during cleaning.
Durable stainless steel kegs are far less likely to split at the seams, shatter, or degrade over time compared to plastic and wood kegs. Their long service lifetime significantly reduces product loss from damaged containers.
Although the upfront cost is higher when used over many years stainless steel kegs will easily pay for themselves over and over compared to the cost of continually having to replace damaged single-use plastic kegs
The pioneering larger craft breweries like Russian River (Famous for cult favorites like Pliny the Elder. Use stainless steel kegs.) Stone Brewing (Major craft brewery out of San Diego. Uses stainless steel kegs exclusively.)
In sensory trials and taste tests, experienced beer drinkers consistently report that beer served from stainless steel kegs tastes perceptibly better and is worth paying the typical minor price premium.
Conscientious craft beer fans can vote with their wallets by intentionally choosing beers packaged in reusable steel cans and kegs, helping sustainable-minded microbreweries maximize product quality and minimize environmental impact.
In a noticeable shift away from plastic and aluminum, small microbreweries are taking a cue from their larger counterparts, increasingly opting for stainless steel cans and kegs. It's an industry-wide movement gaining momentum each year.
Thankfully for microbrewers, stainless steel is not in short supply. With more breweries opting for steel, production has scaled up globally. This ensures small brewers can get the steel kegs they need to meet the world's growing thirst for their innovative brews.
By spreading the word about stainless steel's benefits for freshness and sustainability, forward-thinking brewers get more folks on board. When people realize steel keeps beer tasting great and reduces waste, craft brewers gain fans over mega brands relying on aluminum and plastic.
For brewmasters seeking the freshest pints, stainless steel kegs are a savvy move. They intrinsically align with craft beer's focus on quality ingredients and small batches. By protecting beer from factors that dull fresh flavors, steel kegs help local brewers delight customers with every sip. Next time you're picking up some craft beers, look for the steel keg seal of freshness. It signals peak taste and freshness handcrafted with care.
