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.

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.

What happens when a brewery grows really fast…but still wants to make world-class beer? 

In this episode, I sit down with Mark Gammons, Head of Operations at Tiny Rebel, to talk about what it actually takes to scale production without sacrificing flavour, brand or quality.

We dive deep into the balance between efficiency and volume, how Mark manages production, expansion and quality and why your brew team might be more important than the brewery itself.

Expect honest reflections, tried-and-tested formulas for managing production and plenty of practical gems as we cover:

⚖️ Scaling up while staying true to your roots
🍻 How Tiny Rebel’s brewhouse has evolved over time
🧪 Why fermentation and yeast management are still an art
🏭 The not-so-glamorous side of infrastructure and planning
👥 Why team culture matters more than stainless steel
🥴 And what happens when something goes slightly...off

Mark’s been through it all! From small batch brews to running a serious production machine. This episode is a playbook in keeping things real while growing big.

Innovation and NPD in Beer 🍻

New Product Development - Something DEYA are industry leading in without question!

When brewers from outside the UK ask me ‘which UK brewery should I try’ I nearly always say DEYA. 

Why? Because I know, whatever the style that person loves, DEYA will nail it.

That, in my opinion, is world class NPD.

In this episode, I sit down with Gareth Moore from DEYA to dive deep into their NPD process and what’s coming up in 2025.

We talk hop selection, relationships with suppliers and customer feedback loops.

Gareth’s insights are an absolute goldmine not just for brewers, but anyone involved in the NPD process.

My favourite topics Gareth covered:
•⁠ ⁠The key elements of a killer NPD process
•⁠ ⁠How DEYA approaches innovation without losing what makes them unique
•⁠ ⁠The role of customer feedback in shaping new beers
•⁠ ⁠Lessons learned from brewing failures (and how to avoid them)
•⁠ ⁠Trends that are shaping the future of craft beer

Is Craft Beer Doomed? ☠️

Is it f*%k. 

I'm sure, like most, you are sick to death of the relentless doom and gloom surrounding the craft beer industry.

"It's too saturated"

"Brewery closures LEAP 49%"

"Cost of living means people are spending less"

In this episode I sit down with the iconic Luca Lorenzoni to discuss exactly why these tpyes of headlines are absolutely wrong.

Luca's experience of delivering consistent craft brewery growth over a long successful career, speaks for itself.

My favourite topics Luca discussed

•⁠  ⁠The real state of the Craft Beer Industry right now
•⁠  ⁠The strategies breweries can use to grow their business
•⁠  ⁠The breweries that are nailing it right now and why
•⁠  ⁠What style of brewery he would open if he had to right now
•⁠  ⁠Why 'craft beer is over saturated' is absolutely not important 
•⁠  ⁠Why on-trade is actually really positive for craft beer 
•⁠  ⁠His thoughts on craft beer vs indie beer

I had so much fun doing this episode with Luca, especially as we are both so passionate about what we do.
