4th Generation Australian Winemaker Uses UV

Brown Brothers winery chose Nuvonic's UV disinfection to clean the water used in the wine-making process, ensures bacterial count is kept to zero.


The Brown Brothers winery located in Victoria, Australia, has decided on a Nuvonic (Hanovia) UV system in order to treat the water used in their winemaking process. Our trusted partner, Fluidquip Australia, installed the system.

One of Australia’s leading family-owned wine companies, Brown Brothers, has been making wine in Victoria for over 120 years. Over this time, it has established a reputation as one of Australia’s most innovative wine producers.

Being a fourth-generation family winery, the Australian wine industry has seen many changes. Yet, the cornerstone of its success remains as a varietal wine specialist and winemaking innovator.

With this mantra in mind, the company chose Nuvonic’s (formerly Hanovia) UV disinfection to treat the water needed for its wine-making process. UV delivers the most secure and environmentally friendly water disinfection available, with the UV-treated water used for bottle washing, process water, QC, laboratory water, and just about anything else where clean and bio-secure water is required throughout the winery.

In 2009 Brown Brothers updated its existing UV water treatment system to the latest PureLine AF3 UV system.

“Our UV system has worked perfectly since we installed it in 2009. We routinely get a zero (bacterial) count after the UV.”

“It wasn’t always that way – our old UV system would often return counts for bacteria of 40, 80, or sometimes even 100 CFU (Colony Forming Units),” says Steve Dows from Brown Brothers.

The installed UV system protects Brown Brothers’ water from the risk of water-borne micro-organisms. These can be bacteria, viruses, yeasts, molds, and harmful protozoa such as Cryptosporidium and Giardia, which are chlorine-resistant. It does this without affecting the water’s pH, color, or taste, ensuring there is no impact on the quality, flavor, or aroma of the wine, which is important when you are producing gold medal-winning wines.

“Chlorine is a no-no anywhere in the wine-making process as it can affect the taste of the wine,” adds Steve.

Brown Brothers use a deep bore as its water supply and positions the Nuvonic (Hanovia) UV system after 0.04-micron filters.
UV disinfection has the advantage of using no chemicals and having no by-products in the process. It is effective against all known microbes.

Brown Brothers was awarded several gold medals in the Royal Melbourne Wine Show in 2012. They continue to lay claim as one of Australia’s most iconic winemaking success stories.
