No chemicals and a safer working environment
Grebbestad is not just a favorite among domestic and international tourists, it’s also Sweden’s oldest microbrewery. The facility brews several popular beers such as India Pale Lager, Saison and the Swedish classic Christmas holiday drink julmust.
The brewery, located on the beautiful Swedish west coast, has been using traditional acid and hot water to sanitize the fermentation tanks, filling machines and other process equipment.
They have now upgraded their sanitation routines with an Ozonetech ozone system, resulting in tangible operational benefits and a more gentle environmental footprint.

The Ozonetech RENA Vivo A-series system is connected to tanks and other process equipment during CIP sanitation. The brewmaster Johan Hansson is observing the system during operation.
The problem
Ever since the start in 1995, Grebbestad Brewery has used large amounts of chemicals and hot water to sanitize all process equipment – a necessary procedure to maintain the highest possible product quality and prevent product spoilage. It is one of the most water-intensive and costly operations during production along with chemical handling issues. The excellent sanitation potential of ozone presented an attractive solution for the facility.
The solution
Together with Mellifiq, the brewery installed an Ozonetech high-performance ozone system which provides effective sanitation and disinfection of frequent clean-in-place operations. Ozonetech’s RENA Vivo system enables a turn-key sanitation solution in lieu of acid and hot water which has been used since the start.
An intuitive touchscreen, controlling the amount of ozone concentration during disinfection, enables on-demand sanitation and leaves no chemical residues. No more handling and administration of hot water or hazardous chemicals.
Evaluation
The new Ozonetech RENA Vivo A-series high-performance ozone system has significantly reduced handling of and associated costs for disinfection chemicals. Water savings have also been realized since chemical residues have been eliminated. Sanitation time has been reduced thanks to the high disinfection capacity of the system. Thanks to Mellifiq, the brewery now runs more efficiently and chemical-free.
We are very happy with the new sanitation technology Mellifiq has provided. We are integrating the ozone system into the brewery to cover both fermentation tanks and the filling machine.

The Ozonetech RENA Vivo system is equipped with an easy-to-use control system including a touch screen panel.
