Time & Rye: NZ Whisky Maker Michael Byars Is About To Take You By Surprise
About a year ago, I’d just finished up at a pretty serious whisky operation in Central Otago. But head out to the coast, you’ll find Victorian Oamaru and a pile of NZ whisky history, myth and legends. I’ll let you decide which is which. I just about fell over backwards to taste some remarkable liquid straight from the barrel, in a bondstore which has previously struggled to find it’s way, despite valiant efforts.
New Zealand whisky is getting rewritten in a cold warehouse in Oamaru, where it matures after being fermented (for a wildly long time) then distilled at Speights Brewery, and Michael Byers is the winemaker-turned-distiller behind some of the most exciting spirit coming out of the South Island. If you think you know what New Zealand whisky tastes like (especially NZ Whisky Collection whisky), this conversation will make you look again. Opening a bottle of the latest releases will go even further.
Michael joins Tash to unpack the unlikely path that took him from German wineries and Lincoln University to Helsinki, Dunedin, and Oamaru, where he now crafts whisky with a patience most distillers can’t dream of - stuck in a yield-driven mode of 72hr ferments. But Michael’s result is spirit with real grain character, depth, and a texture that surprises even at cask strength.
You’ll discover:
* Why Michael believes fermentation timing changes everything in whisky
* How he thinks moon phases, atmospheric pressure, and cold conditions can influence long ferments
* What long fermentation and slower distillation do for flavour and mouthfeel
* How soil provenance can show up in whisky, just like it does in wine
* Why 55-litre casks are changing the conversation around spirit-to-oak ratio
We break down the cask programme too, from ex-bourbon and ex-rye to ex-wheat, and why each one brings something distinct to the liquid. Michael explains how American oak, first-fill barrels, and the previous life of a cask can shape everything from tropical fruit and clover honey to linseed oil, spearmint, hazelnut, and that unmistakable wet-stone mineral edge.
Tash tastes through a standout 3-quarter ex-rye, 1-quarter ex-bourbon expression and makes the case for why this is one of the most compelling whiskies in New Zealand right now. Michael also shares why he’s obsessed with older barrels, why he won’t throw any cask away too quickly, and why New Zealand whisky should be bigger than just red wine finishes.
If you care about flavour, barrel strategy, provenance, and what makes a whisky feel genuinely alive, this is essential listening. A smart, candid, deeply sensory conversation for whisky lovers, spirit geeks, and anyone curious about where New Zealand whisky is heading next.*AI was used to transcribe sections of this podcast for notes.
