Innovation and Packaging

Steel keg programs for on-premise beer product sales have long been the norm in the market. The programs deliver really good quality—if managed appropriately. When they are not, inconsistent beer high quality results. Steel keg programs also arrive with other disadvantages: the expense of returning the kegs, the expense of the gasoline and regulator techniques necessary to produce the beer to the faucet, and the inability to evacuate all of the solution from the keg.

Claims Joe Pagliaro, Director of Innovation and Packaging United states of america, “The issues have been acknowledged for a lengthy time in the sector, but no brewer has ever place the methods guiding it to locate a solution.” Final yr, in response to these difficulties, Heineken introduced a new keg system to solve these concerns, foremost between them making sure the high quality of its beer as soon as it leaves its facility.

“As a brewer, the way beer is served at any retail place is largely out of our palms,” Pagliaro says. “At Heineken, we are obsessed with good quality and will in no way settle for our beers not being served the way our beermasters intended.”

Released nationally in May 2014, the BrewLock PET keg method gets rid of a lot of potential fall short points of recent draught methods, Pagliaro clarifies. “So prolonged as merchants continue to thoroughly clean their draught lines, and serve the beer chilly and in clean glasses, BrewLock does the rest to make certain the beer the client is drinking in the U.S. tastes as very good as if they are ingesting from the filling line at the brewery.”

Brewery-refreshing beer
In engineering the BrewLock, Heineken’s principal objective was to develop a technique that could supply brewery-clean beer, securely. “Our goal was to guarantee to the ideal of our capability that the beer hitting the consumer’s lips preferences the specific same way every single time, and that at the stop of the keg, we did not have a pressurized plastic balloon that could probably damage an individual,” Pagliaro explains.

The BrewLock is not the initial plastic keg. But Heineken felt every competitive method had factors that could be enhanced on in its very own design. The outcome is a multi-component technique that includes two twenty-L PET bottles a valve manufactured from polybutylene terephthalate (PBT)/nylon/nitrile rubber (NBR)/metal a PET collar and a polypropylene protecting cap. “Each ingredient is engineered to really stringent tolerances to make certain every keg works flawlessly, every single time,” says Pagliaro.

The principal components are the two PET bottles. These are created with one within of the other. The outer bottle is obvious PET the inner—a significantly less rigid, collapsible structure—is silver and includes additives to supply the ideal defense to the beer, including pigments to defend from a entire spectrum of light waves and oxygen scavengers to avert oxidation, for example. These additives permit up to a 6-thirty day period shelf life for the beer. The bottles are currently injection extend blow molded off-web site. Several suppliers have lent their technical assist, but Heineken chooses not to identify them. In the coming months, Heineken ideas to commission in-line bottle blowing to increase adaptability and performance. The keg program also will come with a proprietary air compressor.


The program operates as follows: After the kegs have been sufficiently cooled at the client web site, a proprietary EasyFit coupler is hooked up to the keg. The compressor—which is about the measurement of a shoe box and is plugged into any standard electrical outlet both inside or exterior of the cold room—automatically pressurizes the space amongst the two bottles to a recommended pressure with standard ambient air. When the faucet take care of is pulled, the coupler opens a valve to the inner bottle whereby the force amongst the bottles squeezes the beer out of the internal bottle to the faucet. When the tap handle is returned to regular, the valve closes, and the compressor re-pressurizes the space in between the bottles. The technology guarantees that no outside the house air, CO2, or mixed gases occur in speak to with the beer and final results in the evacuation of nearly a hundred% of the beer from the internal bottle.

“The beer can never be impacted by oxidation, and it has ideal and constant carbonation and fantastic, limited bubbles for the best head, or foam,” states Pagliaro.

To make sure client protection, the coupler that connects the beer line to the keg functions passive degassing. This means that when the coupler is detached, the keg immediately degasses itself without the consumer possessing to do anything at all. According to Pagliaro, competing plastic kegs remain pressurized once uncoupled. “While beer quality is always at the prime of our listing, protection is non-negotiable,” he states. “No subject the rewards of our offers, safety will never be compromised at any value.”

Extra rewards
Apart from becoming selected for their operation, the elements in the BrewLock system ended up also selected for their simplicity, in purchase to minimize potential failures, as properly as their minimal cost and recyclability. Since the kegs are non-returnable, they essential to be produced with the the very least costly substance that could also be recycled.

Between the sustainability advantages, the keg is 25% lighter than a steel 1∕6 barrel and employs much less materials, ensuing in the shipment of a lot more beer and significantly less packaging. No return excursion to Heineken signifies considerably less fuel is employed in transportation. In addition, the compact, twenty-L keg is shipped in a corrugated circumstance that provides a scaled-down footprint than a steel keg and can be stacked horizontally when not in use. “The kegs and corrugated bins are a hundred-p.c recyclable,” claims Pagliaro. “The boxes are also produced from unprinted kraft pulp and printed with only 1 colour. Mixed, we are using less material and vitality, which is not typically the situation for this kind of novel innovations.”

In 2013, Heineken did a brief examination market in Hartford, CT, that resulted in a +ten% boost in Rate of Sale. Because the countrywide launch, Pagliaro states the reaction has been even greater. “We exceeded sales targets and set up more than three,000 tap handles in 2014,” he suggests. “The Fee of Sale of Heineken draught was furthermore 25 %. Perhaps the best testomony to the power of BrewLock although is that revenue of Heineken bottles in accounts in which BrewLock was put in was plus 13 p.c.”

In the U.S., Heineken at the moment gives on-premise buyers its Heineken Lager and Newcastle Brown Ale in the BrewLock. In Europe, the company has also introduced a sister variation, The Sub, for at-residence use.
