Blog: Why Beer Tanks Are a Game-Changer for Events

When it comes to serving beer at large-scale events—whether it’s a music festival, sports match, or trade fair—ensuring consistent quality and minimizing waste is crucial. Traditional keg systems often fall short under high demand, leading to long queues, inconsistent pours, and unnecessary losses. That’s where beer tanks from Duotank come in.

Consistent Quality, Every Time

Duotank’s innovative Bag-in-Tank system ensures that beer remains fresh and perfectly chilled from the brewery to the tap. The beer is stored in airtight disposable bags inside the tank, which are gently pressed by compressed air—without the need for added CO₂. This not only preserves the beer’s original taste and carbonation but also extends its shelf life up to 12 weeks. Even in the heat of summer, your beer stays cold and consistent, pint after pint.

Minimal Tap Loss, Maximum Efficiency

One of the biggest challenges at events is tap loss—beer wasted due to foam, temperature fluctuations, or inefficient keg changes. Duotank’s mobile event tanks are designed for continuous flow and minimal handling. With fewer interruptions and no need to swap kegs, staff can serve more customers faster, with virtually no waste. That means happier guests and higher profits.

A Sustainable Choice for Modern Events

Beyond quality and efficiency, beer tanks offer a significant environmental advantage. By replacing hundreds of single-use kegs with a single reusable tank system, event organizers drastically reduce packaging waste and transport emissions. The Bag-in-Tank system eliminates the need for CO₂ cylinders and reduces the frequency of beer deliveries, cutting down the event’s overall carbon footprint. It’s a smarter, greener way to serve beer—without compromising on taste or performance.

Real-World Impact: VM Events at TT Assen

A great example of the power of beer tanks in action comes from VM Events, who recently deployed Duotank’s event tanks at the TT Assen 2025. It was their first time using this system, and the results were impressive. The video recap of the event highlights how the tanks enabled a smooth, large-scale beer supply with consistent quality and minimal waste—proving just how effective this solution can be for high-demand environments.
