John Teeling joins Business Builders for a candid, wide-ranging conversation about risk, resilience, and the 20-year bet that helped revive Irish whiskey. 

When John entered the industry in the 1980s, Irish whiskey had fallen to under 2% of the global market. Consolidated into a struggling monopoly and written off by many, it looked like a declining category. 

Instead of walking away, he built. 

From buying a shuttered chemical plant in Dundalk and installing second-hand pot stills, to navigating bank loan recalls, political pressure, and years without meaningful profit, John explains what it really took to build Cooley Distillery; and why the payoff took nearly two decades. 

But this episode goes far beyond whiskey. 

John shares lessons from decades in mining, resources, and investing, where high risk doesn’t mean high reward, but high probability of loss. He breaks down the difference between risk and uncertainty, why “the Euro is an orphan,” and why unsophisticated investors should never be in speculative markets. 

This is a conversation about long-term conviction, imposter syndrome, stubborn belief, and building businesses that outlast downturns. 

At 80 years old, John reflects on endurance, energy, family, legacy, and what it really means to take responsibility when you persuade others to back your vision.
