Are Non Alcoholic Beers Safe?
With demand for no and low alcohol beer BOOMING, more and more breweries are brewing their own.
But when you remove alcohol, you remove one of the strongest safety mechanisms in beer.
And with the rise of unfiltered, unpasteurised NA beers hitting shelves, this episode asks a simple but essential question:
How do you make NA beer safe?
To help answer it, I’m joined by Dr Greg Rachon and co host and brewing legend, Sean Knight - Siren Craft Brew.
We dig into the risks, the latest microbiological research and the practical steps brewers need to know.
What we cover:
- Why alcohol has been silently keeping beer safe for centuries
- What happens when you take it away
- The key safety mechanisms left behind for NA products
- New research on pathogens and spoilage microorganisms in NA beer
- The role of carbonation, packaging and preservatives
- Why beer line hygiene matters more than ever
This episode features some of the most up to date research on NA beer safety from Dr Greg Rachon, alongside industry insight from Sean Knight.
Huge thanks to Lallemand for supporting the show and for their ongoing work with the LoNa yeast strain.
