    Ep 43 - The Real Dangers of Non-Alcoholic Beer - Dr Grzegorz Rachon - CO HOST - Sean Knight Siren

    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.

    Ep 42 - Chillers, Heat Recovery & OpEx: What Every Brewer Needs to Know - Jon Keyte

    This year alone, I’ve seen multiple breweries unknowingly bleed cash through their refrigeration systems. Why? Because chillers are often misunderstood, undersized or poorly maintained. And they happen to be one of the biggest operational costs in any brewery. In this episode, I sit down with Jon Keyte from RefCool, one of the sharpest minds in refrigeration, to break down everything a brewer needs to know about chillers. From sizing to heat recovery, operational efficiency and how you can use your chiller to heat water to 50c. If you're buying a chiller, running a chiller, or trying to save energy in your brewery, this is essential listening. What we cover: •⁠  ⁠Why chillers are often over sized and draining your margins •⁠  ⁠How to correctly size a chiller (it’s not what you think) •⁠  ⁠The truth about compressor types, ambient temperatures and glycol tanks •⁠  ⁠Heat recovery that turns cooling into hot water •⁠  ⁠How to monitor, maintain and future-proof your system •⁠  ⁠Real world CapEx versus OpEx comparisons that could save you thousands This one is practical, no nonsense and deeply important for any brewer looking at a new chiller or looking to reduce their operational costs.
