In the fight against Brett, winemakers need to have access to the best technology possible. For many years now, the Australian Wine Research Institute (AWRI) has been developing cutting edge technology, and engaging in 'on the ground' communications work to bring this technology to Australian producers.
Recent advances in genome sequencing techniques has allowed the AWRI to take a closer look at Brett and to determine what causes it's sulphur resistance, and what can be done about it in a targeted manner. Check out the article"Advancing the frontline against Brett" - it's well worth a read.
For our two cents, at this current stage, your best bet to help control Brett growth is to have a thorough hygiene regime in place. This will always be the case, not only for the fight against Brett, but also against all unwanted microbes in your wine.
