Inside The Blending House With Master Blender Ashley Barnes [Extended Episode]

This is a different kind of episode and an extra long one, because Ashley Barnes takes us deep into the actual process of blending bourbon at The Blending House in Kentucky.

Ashley is the Master Blender here, and instead of simply pouring us a finished whiskey, she walks us through how a real blend comes together. Starting with 18 barrels, she explains how she evaluates them, separates them into flavor groups, and builds them back up into something balanced, expressive and true to the intended profile.

We talk about base notes, fruit notes, top notes, vanilla-forward barrels, and why some barrels are better as single barrels while others need to be part of a bigger blend. Ashley also explains how blending can work across mash bills, how she can often predict when a barrel will nose-dive with age, and why proofing is one of the biggest turning points in the whole process.

Along the way, she shares the chemistry behind flavor, how compounds behave differently in ethanol and water, why she lets blends rest before making decisions, and how she brings in outside palates to challenge her assumptions and refine the final product.

If you’ve ever wondered how a bourbon brand keeps its flavour profile consistent, or how much work really happens behind the scenes before whiskey hits the bottle, this episode is a proper masterclass.
