Ever wonder where the magic happens after the spirit leaves the still? Well, it’s all about the barrel and the warehouses that they mature in, or as they are referred to in the industry, rickhouses. These aren’t your average storage units – they’re more like aging chambers where whiskey transforms into liquid gold. And since 100% of the color of whiskey and up to 70% of the taste come from the barrel, this is the most important aspect of the process. 

A Brief History

Back in the day, whiskey was often stored in whatever space was available, from barns to caves. But as the industry grew, folks realized that proper storage was key to quality. Enter the rickhouse, a purpose-built structure designed to optimize the aging process. These buildings have evolved over the years, from simple wooden structures to massive, climate-controlled facilities.

Size Matters (Sometimes)

Rickhouses come in all shapes and sizes. Some are small, family-owned operations with a few thousand barrels, while others are massive complexes holding millions of gallons. But size isn’t everything. What really matters is how the warehouse is managed. Factors like temperature, humidity, and airflow all play a pivotal role in how the whiskey matures.

The Temperature Tango

Speaking of temperature, it’s a big deal in the aging process. You see, whiskey breathes through the wood of the barrel. As the temperature changes, the wood expands and contracts, pushing the whiskey in and out of the pores. This interaction with the wood is what gives whiskey its color, flavor, and complexity.

In warmer climates, the temperature swings are more dramatic, leading to faster aging. That’s why a whiskey aged in Kentucky might be ready in four or five years, while a Scotch whisky in a cooler climate might take a decade or more.

The Angel’s Share

Now, here’s a fun fact: some of the whiskey evaporates during aging. This is called the “angel’s share,” and it can be a significant amount, especially in warmer climates. So, while we’re all enjoying our drams, the angels are having a party of their own!  If you’ve ever stepped foot in a rickhouse on tour, you know the smell.  If you haven’t, do so.  It is probably my most favorite smell. I wish there was a candle that could replicate it.

The Art of Aging

Ultimately, aging whiskey is an art. It’s about understanding the environment, selecting the right barrels, and knowing when the whiskey is just right. And while there’s some science involved, there’s also a bit of magic. So, take a moment to appreciate the journey it took from the still to your glass, all thanks to the humble rickhouse.
