FAQ

Manual filling: should I vent a KeyKeg and/or flush it before filling?

In order to minimize oxygen uptake, we recommend that you vent the KeyKeg with a coupler before filling. For optimum filling, it is advisable to rinse the inner bag with CO2. It is not necessary to fill the bag entirely with CO2. Flushing with 5 liters of CO2 is enough. After that, the CO2 should be removed with a coupler. See also the instructions for manual filling.

How sustainable is the KeyKeg?

The KeyKeg is recyclable and consists of on average 30% recycled plastics. In addition, a KeyKeg saves more than 60% on transport costs, and, in contrast with steel kegs, does not need to be washed with hot water and chemicals. This is part of what makes KeyKeg packaging more sustainable.

How should I clean my dispensing lines as a KeyKeg user?

You can clean the lines the same way you normally would by connecting a KeyKeg cleaning adaptor. Connect the KeyKeg coupler with the adaptor to a cleaning canister or the existing cleaning system. You will find the accessories you need for this in the KeyKeg webshop.

How long does beer stay fresh in a KeyKeg?

In proper storage conditions, beer stays fresh as long as in a steel keg. Depending on the the ingredients, the type of beer and the alcohol content, possibly longer. Other factors that play a role are pasteurization and the quality of the filling procedure.  Some brewers even use KeyKegs to age beers!

How long does beer stay fresh when the KeyKeg is tapped?

After tapping, beer will stay fresh in a KeyKeg for 3-4 weeks on average. The shelf life of the beer depends on the type of beer, storage conditions and cleanliness of the draft system.

How can I recycle a KeyKeg?

The first step is to deflate the keg using the KeyKeg deflating tool or the Micro Matic dispense head with built-in deflating switch. Then deposit the KeyKeg with other recyclables. Keep the deflating tool for the next time. This instruction video shows the process to deflate a KeyKeg for recycling.   
Always depressurize in a well-ventilated area!

How many filled KeyKegs fit on one pallet?

KeyKeg 10 L: 100 KeyKegs
KeyKeg 20 L:   60 KeyKegs
KeyKeg 30 L:   36 KeyKegs

How many empty KeyKegs fit on one pallet?

KeyKeg 10 L: 140 KeyKegs (pallet type BLOCK: 48” x 40”, 120 x 100 cm)
KeyKeg 20 L:   80 KeyKegs (pallet type BLOCK: 48” x 40”, 120 x 100 cm)
KeyKeg 30 L:   48 KeyKegs (pallet type BLOCK: 48” x 40”, 120 x 100 cm)

Can a KeyKeg be filled on an existing line for steel kegs?

This depends on the manufacturer and the type of filling line. Contact your supplier directly about the possibilities. On the KeyKeg website, you will find some suppliers of filling lines who manufacture filling machines for KeyKegs.

Can I send empty KeyKegs for recycling with the normal waste?

KeyKegs are 100% recyclable when empty. You can give your empty KeyKegs to your local recycling processor – if they have questions, refer them to Lightweight Containers: +31 (0) 223 760 760 or info@keykeg.com

What kind of coupler is a KeyKeg fitted with?

All KeyKegs are fitted with a modified GR coupler. The probe has been modified so that it works perfectly with the KeyKeg Bag-in-Keg™ technology. This technology separates the dispensing gas from the beverage. The KeyKeg couplers can be ordered directly from our webshop.

When dispensing, only foam comes out of the tap – what should I do?

This can result from a number of causes such as dispensing pressure, secondary fermentation, temperature, etc. Lightweight Containers has created an instruction video showing how to mitigate problems with foam. Click here to see the video.

Where and how can I order KeyKegs and accessories?

You can order any of the accessories and small quantities of KeyKegs (depending on the size, 6 to 8 units) via the KeyKeg webshop, your online Netstore account or by e-mail to your account manager. For more information: tel. +31 (0) 223 760 760 or e-mail: info@keykeg.com

Where can I order filled KeyKegs?

You will find a number of brewers and beverage distributors who are working with KeyKeg on our KeyKeg Users platform. You can contact them directly, or you can ask your existing suppliers to deliver your beers in KeyKeg.

Why does the KeyKeg make a cracking sound during filling?

Every KeyKeg has the added safety of Double-Wall™technology. When filling a KeyKeg, the double wall adjusts to the higher pressure applied. This causes both walls to shift slightly sometimes leading to a cracking sound as the 2 layers interact. Every KeyKeg is tested to 7 bar (over 100 PSI), so rest assured. The KeyKeg can withstand considerably higher pressure than applied during filling.

What does the Double-Wall™ Technology do?

Every KeyKeg is fitted with two walls of PET. The 2 layers work together dynamically making the KeyKeg safer and more robust compared to other one-way kegs. This means a KeyKeg can take higher pressures and is more resistant to damage during handling operations such as filling, storage, transport and dispensing. Every KeyKeg is tested to 7 bar / 101 PSI. The independent research institute, VLB, has tested the properties of KeyKeg extensively.

How long will an empty KeyKeg keep?

Unfilled KeyKegs will last at least 18 months.

What is the maximum pressure for a KeyKeg?

The maximum dispensing pressure is 4.1 bar / 59 PSI. The safety valve on every KeyKeg coupler prevents higher dispensing pressures. The maximum pressures for transport and storage are:
KeyKeg 10 L, 20 L, 30 L: 6 bar at 40 Celsius °C/104 Fahrenheit °F

Which beers can go into a KeyKeg?

Any style of beer can be filled into a KeyKeg. Some of our customers even age lambics, imperial stouts and other beers in the KeyKeg with great results. Forced carbonation of the beer is not possible in a KeyKeg. Under the right conditions, secondary fermentation is possible, but it is important that the CO2 content does not rise too far. Contact us for more information on measuring the CO2 content in a KeyKeg or watch the video.

The environmentally friendly one-way keg

We take our environment into account, even during the design phase. A KeyKeg easily meets the environmental criteria of the European Union. Every KeyKeg is made of 30% recycled material already. The gripring and basecup are made of 100% recycled PP. Every day we strive to recycle every KeyKeg to produce new KeyKegs.
