In the ever-evolving craft beer industry, innovation isn’t just limited to brewing techniques and unique flavors. Packaging and distribution methods have also seen significant advancements, one of the most notable being the introduction of crowlers. These 32-ounce aluminum cans have transformed the way beer enthusiasts enjoy their favorite brews at home. In this article, we will delve into the world of list crowlers, exploring their history, benefits, and impact on the craft beer scene.
What Are List Crowlers?
List Crowlers a portmanteau of “can” and “growler,” are large, 32-ounce aluminum cans designed to hold draft beer. Unlike traditional glass growlers, which can be resealed and reused, crowlers are single-use containers. They are filled and sealed at the brewery, ensuring that the beer remains fresh and carbonated until it is opened. This innovative packaging method has quickly gained popularity among craft beer aficionados and breweries alike.
The Inception of List Crowlers
The concept of crowlers was introduced by Oskar Blues Brewery in 2013. Seeking a more convenient and reliable way to package draft beer for to-go sales, they partnered with Ball Corporation to create the crowler canning system. This new packaging option was an instant hit, providing a lightweight, portable, and recyclable alternative to traditional glass growlers.
Advantages of List Crowlers
Freshness and Quality
One of the primary advantages of crowlers is their ability to maintain the freshness and quality of the beer. Since they are sealed on-site at the brewery, crowlers ensure that the beer remains carbonated and free from exposure to light and oxygen. This preservation method keeps the beer tasting as it would straight from the tap, even after several weeks.
Convenience and Portability
Crowlers are lightweight and portable, making them an excellent choice for outdoor activities such as hiking, camping, and picnics. Unlike glass growlers, which are prone to breaking, crowlers are made of durable aluminum, reducing the risk of damage during transport. Their single-use nature also eliminates the need to clean and return the container, adding to their convenience.
Sustainability
Aluminum crowlers are fully recyclable, making them an environmentally friendly option for beer packaging. Recycling aluminum requires significantly less energy compared to producing new cans, helping to reduce the overall environmental impact. This sustainability aspect is increasingly important to both consumers and breweries committed to eco-friendly practices.
The Process of Filling Crowlers
Brewery Equipment
The process of filling a crowler begins with specialized equipment known as a crowler canning machine. These machines are designed to fill and seal the 32-ounce cans quickly and efficiently. The machine purges the can with CO2 to eliminate oxygen, fills it with beer, and then seals it with a lid, ensuring that the contents remain fresh and carbonated.
Filling and Sealing
Once the canning machine is set up, the crowler is purged with CO2 to remove any oxygen that could potentially spoil the beer. The beer is then poured into the can, usually directly from the tap. After filling, the can is sealed with a lid using the canning machine, creating an airtight seal that keeps the beer fresh until it is opened by the consumer.
The Impact of Crowlers on the Craft Beer Industry
Increased Sales and Accessibility
Crowlers have significantly increased sales for many breweries by offering an additional option for to-go beer. This packaging method allows customers to enjoy their favorite brews at home or on the go, without the need to commit to a larger growler. The convenience and portability of crowlers have also made craft beer more accessible to a wider audience.
Supporting Small Breweries
For small and independent breweries, crowlers offer a cost-effective way to package and sell their beer. Unlike bottling lines, which can be expensive to set up and maintain, crowler canning machines are relatively affordable and easy to operate. This has enabled many small breweries to expand their reach and offer to-go options without a significant financial investment.
Enhancing the Beer Experience
List Crowlers have enhanced the overall beer experience for consumers. By ensuring that the beer remains fresh and carbonated, crowlers allow drinkers to enjoy the same quality and taste as they would at the brewery. Additionally, the ability to take beer on outdoor adventures or share it with friends has made craft beer more versatile and enjoyable.
How to Enjoy Beer from Crowlers
Proper Storage
To ensure that beer from a crowler maintains its quality, it is essential to store it properly. Crowlers should be kept in a cool, dark place, such as a refrigerator, to prevent exposure to light and heat. This helps to preserve the beer’s flavor and carbonation, ensuring a great drinking experience.
Pouring and Serving
When it comes time to enjoy beer from a crowler, it’s important to pour it correctly. To minimize foam and maximize flavor, tilt the glass at a 45-degree angle and pour the beer slowly down the side. As the glass fills, gradually straighten it to achieve the perfect pour with a nice head of foam. This method helps to release the beer’s aromas and enhances the overall drinking experience.
