Keg Science and Testing

All products are subject to exhaustive organoleptic, logistics and heat tests by Petainer’s own labs and by globally recognised independent institutions such as VLB, TOPA Institute and Hochschule Geisenheim University.

When it comes to using PET kegs, one of the most frequently asked questions is that of product quality and protection.  We recognise that if our customers’ products do not arrive in optimum quality to be served in bars, restaurants and cafes, their reputation and brand is at risk.

That’s why all our products are subject to exhaustive organoleptic, logistics and heat tests by Petainer’s own labs and by globally recognised independent institutions such as VLB, TOPA Institute and Hochschule Geisenheim University.

Suitability of petainerKeg for draught packaging of beer

We commissioned VLB Berlin, an independent and highly regarded authority on the beverage industry to compare beer quality in our PET kegs to other packaging types.  An independent panel test evaluated and compared beer in petainerKeg and steel kegs.

The trial concluded that over nine months, the development of the different beers tested was generally similar when stored in metal and in PET Kegs, leading to the conclusion that PET and metals have similar performance along the storage time.

The impact of bottling and storing wine in petainerKeg

We asked Hochschule Geisenheim University to look at the difference between wine stored in a petainerKeg and metal kegs.  These tests showed that petainerKeg delivers the wine with a visual appearance on par with wine stored in glass bottles and metal kegs, and does not negatively impact on sensory experience or taste quality thanks to a combination of active and passive barriers maintains gas barrier properties for storage of wine.
