Resealable Crowler

Oskar Blues Brewery*, Ball Corporation*, Dayton Systems Group (DSG)* and Actega DS announce the new Resealable Crowler which was made available at the Craft Brewers Conference in Washington D.C. in April and will be presented at Interpack in Düsseldorf, 4.- 10. May.

First introduced in 2014, the original Crowler (can plus growler) is a single-use can that comes in 25 oz (750 ml) and 32oz sizes (ca. 946 ml). They may be both filled and sealed with a custom machine that features a design based on one commonly used for canning perishable food. It is filled with fresh draft beer then seamed at the bar using a table-top seamer to be sold to consumers as a take home container.

The reasons behind the popularity of this development are apparent. It travels much better than glass and can be readily taken to parks, campgrounds and down the river or to a friend’s house. The beer is as fresh tasting as straight from the tap and there are no leakages because it is mechanically sealed. It has the superior qualities of a can - for the EU market composed of 68 percent recycled content -, includes the ability to block out light and oxygen all while providing a shareable 100 percent recyclable container.

As the popularity of the Crowlers has surged, Oskar Blues has sold more than 1.000 Crowler systems in the United States to bars and breweries with tasting rooms. Jeremy Rudolf, who manages Crowler integration at Oskar Blues Brewery in Longmont, Colorado, says, “We get off on pushing the limits, doing things differently and the Resealable Crowler is another step of innovation to take advantage of what the can package has to offer from behind the bar”. In cooperation with DSG’s lug thread technology and Actega DS,

the 32oz Resealable Crowler includes a cap containing an oxygen scavenging barrier – a small piece of TPE (thermoplastic elastomere) inside – that both helps remove oxygen from the beer poured into the container as well as gives the lid a better seal.

DSG delivers the Cap Can domes and lined caps for the new Resealable Crowler. According to Vicki Bachmann, Marketing Manager at the company, “People in the craft beer industry are focusing on increasing their profitable draft business: the Resealable Crowler accomplishes this while offering a new take-home option that adds consumer value by being easy to open, pour and reseal.”

The Crowler® name is a Ball trademark, and it refers to the container itself. The machine used to close it is made by an American company and is sold through Oskar Blues. Then, Bachmann adds, “DSG’s unique lug thread and seal lining technologies, utilizing Actega’s seal material, combines to finish this innovative package for the craft beer industry”.

Finally the TPE sealing compound for closures – SVELOX® 5200 L – is part of Actega DS oxygen scavenger product family, protecting beverages from oxygen induced taste deterioration. It was developed for use on fruit juices, beer and mineral water and shows excellent elastic and organoleptic properties. This compound is based on SVELON® 520L with the oxygen scavenger package. After this compound became approved with the DSG Cap Can, breweries asked for reduction of the oxygen in the headspace to ensure taste properties and shelf life of the beer within the container. Therefore the SVELOX® 5200 L became a suitable solution for this specific application.
