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.
To disinfect water in the winemaking process, Brown Brothers winery in Victoria, Australia has installed a UV disinfection system. The system was installed by our partner, Fluidquip Australia.
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, it has seen many changes in the Australian wine industry, yet the cornerstone of its success remains as a varietal wine specialist and winemaking innovator.
With this mantra in mind, the company selected 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 disinfection system to the latest AF3 UV system.
“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 disinfection system safeguards Brown Brothers’ water from the risk of water-borne micro-organisms such as bacteria, viruses, yeasts and moulds, as well as harmful protozoa such as Cryptosporidium and Giardia, which are chlorine-resistant. It does this with no effect on the water’s pH, colour or taste, ensuring there is no impact on the quality, flavour 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 Hanovia UV disinfection system after 0.04 micron filters.
UV disinfection has the advantage of using no chemicals and
it introduces no disinfection by-products into the process. It is effective against all known microbes.
After being awarded several gold medals in the Royal Melbourne Wine Show in 2012, it’s clear that Brown Brothers continue to lay claim as one of Australia’s most iconic winemaking success stories.
