What’s Bardstown Bourbon Discovery Series #4? 

Bardstown Bourbon Discovery Series #4 is the fourth installment of the said series, which showcases the art of blending. 

This fourth installment highlights old and rare spirits sourced from different origins (undisclosed). It’s produced in small batches and is currently hard to find these days. 

Bottled at 115-proof (or 57.5% ABV), it’s deep and complex, which we find suitable for experienced drinkers.

So far, Bardstown has released nine variations of the Discovery Series. 

For your reference, here’s the full list: 

  • Discovery Series #1 – 60.6% ABV
  • Discovery Series #2 – 61.1% ABV

Tasting Profile 

Pouring Bottle of Whiskey on a Glass


Packed with brown sugar and notes of molasses. The aromas of oak and vanilla follow, complemented by the slight citrus and menthol-like rye spice hints.  


It feels creamy on the mouth. Along the creaminess shows the sweet fruit notes, and the brown sugar from the nose extends to the palate. 

As it develops, the cinnamon and rye spice notes show up, followed by sweetness from dark chocolate, vanilla buttercream, and honey. 


It’s sweet and savory. But along with that, there’s some heat with heavy oak, char, and rye spice notes.

As expected from its proof, the warmth of the spirit lingers on the throat and chest. 

Our Thoughts 

First Sip

On our first sip, it’s fruity and sugary. There are some wood notes, but it’s mellow and soft. Initially, we thought it was not complex due to the sweet notes, contrasting its higher proof. In short, the proof of this spirit isn’t that evident in just one sip.  

Second Chance

As we continue, the tasting notes start to get deep and robust. The woody notes and rye spiciness are getting apparent. 

This time, the old-aged bourbon blend in this series comes out, significantly influencing the overall profile of the spirit. 

But what we like about this series is that the oak and spicy notes are balanced and not that overwhelming.  

Why We Like It 

Bardstown Bourbon Discovery Series #4  Bottle Label

We like Bardstown Bourbon Discovery Series #4 because: 

  • It’s a well-crafted expression, showing expertise and character. The fruitiness, sweetness, heat, oak, and spice are well-balanced. We don’t find any off notes in this spirit (based on our preference). 
  • It delivers richness, depth, and a nice body at once, which is hard to find in other bourbon brands.
  • If you like Series #3, you’ll surely like this one as it’s a better version and far more desirable than the #2 release.  


  • It’s quite complex for beginners. If you’re new to bourbons, you’ll find this overwhelming. 
  • Another thing, it’s quite pricey. (But if you have money to splurge on this spirit, why not.)
  • This is not an ideal everyday bourbon drink. Aside from its high price, it’s rare. You can’t easily find a bottle of this series in local liquor stores, even online stores. 

Bardstown Bourbon Discovery Series #4 Rating 

All things considered, Bardstown Bourbon Discovery Series #4 is 5 out of 5. 

“Bardstown Bourbon has quickly established itself as a distilling leader for premium bourbon brands.”

— Chris Trick, Investment Partner at PPC

We rate it a perfect 5-Star as it’s high-quality, expensive, and rare.

This is the type of bourbon suitable for very special occasions. (It’s hard to find, so you better turn on your whiskey-hunting skills)

To Sip or Skip?

Obviously, this spirit shouldn’t be skipped. It’s worth sipping, and most importantly, it’s worth the money.

It’s complex, but given its blend and proof, it’s flawless. Mind you – we’re used to the different complexities of whiskeys. 

And based on our experience (and preference), this is an excellent blend: smooth and balanced despite the strong alcohol and flavor, plus the heat. 

If you have yet to purchase a bottle of this series, you can try other alternatives like:

  • BBC Fusion 8, 95.5-proof
  • Origin Series Bourbon, 96-proof
  • Founders KBS Stout Finish, 100-proof

This company is known as an innovative distiller and bottler of several premium ryes and Kentucky bourbon brands [1], like Belle Meade, High West, and Jefferson’s.

Yes. Bardstown in Kentucky is the “Bourbon Capital of the Word.” It is home to the “Kentucky Bourbon Festival,” world-famous distilleries, and even new craft distillation facilities.  

Where is Bardstown Bourbon sourced?

Bardstown bourbon has been sourced from different distilleries across the Kentucky region before.

Now, BBC is moving away from sourcing to making their own whiskeys [2]. 

Final Say

The Discovery Series #4 is a wonderful blend made from three old-aged Kentucky Bourbons.

The nose is aromatic, with a creamy texture and sweet fruit notes on the palate.

The edge of this whiskey lies in the finish; it carries the entire experience, delivering a smooth and satisfying feel in every sip.

We’d love to hunt a bottle of this spirit again.
