All About Michter’s US-1 Sour Mash Whiskey

The term “Sour mash” in Michter’s refers to the process used to make Michter’s US1 Original sour mash whiskey

This method involves taking some fermented mash from one batch and starting the fermentation process on the next batch.

It’s said that this method makes the whiskey more complex and sweet.

The Original US*1 Sour Mash whiskey from Michter’s is labeled as a whiskey instead of a Bourbon.

The mash bill is undisclosed, but there are speculations it contains less than 51% corn, which is less than the minimum amount required to be called a bourbon.

A combination of sweet notes such as nutmeg and fresh apple mingle with hints of vanilla and cinnamon for a warm, comforting aroma. 

This scent is hard to fault as it heavily delivers the “bourbon” aroma with hints of anise. 


Michter's Glasses of Whiskey

A good whiskey should have a good sip, and this one is no different.

It has a variety of sweet flavors like coffee cake, butterscotch, and vanilla, which are all well-rounded and satisfying. 

Very old-fashioned in nature, but the combination of cherries, raspberries, and cinnamon buns is savory.


The combination of rye spice and a ramp-up in heat creates a sharp contrast to this drink’s smooth and sweet palate.

A layer of dryness then wraps the finish, which strips the sweetness. 

Fun Facts About Michter’s US-1 Sour Mash Whiskey 

History & Origin

The original Michter’s distillery was established in Schaefferstown, Pennsylvania. It produced various products such as Old Overholt and Michter’s Original Sour Mash. 

It also had a connection to C. Everett Beam, one of its master distillers.

During the 1990s, Joseph Magliocco, the president of Chatham Imports, partnered with Richard Newman, known for his work with Old Crow, Wild Turkey, and Old Granddad, to revive the brand. 

They opened a facility in Louisville, Kentucky, where they bottle and release a variety of highly regarded whiskeys and bourbons.

Production Process 

Michter's Distillery Equipment

Michter’s didn’t disclose the exact mash bill of the US1 Sour Mash Whiskey.

But they’re very transparent about the process of producing this spirit, which undergoes the following:

  • Michter’s used wood that has been properly dried and thoroughly treated for around 18 to 48 months to enhance the natural flavor and reduce the levels of tannins added to the whiskey.
  • Before charring, the barrels are toasted to add more flavor and hue to the spirit. 
  • Next, it enters the barrels at 103-proof for aging.
  • While aging, it undergoes heat cycling to absorb more flavors. 
  • Then, it will proceed to chill filtering to remove the flavor and aroma that can be lost through carbon filtration. 
  • Finally, it’s bottled at 86-proof (or 43% ABV).  

Age Statement & Barrel Proof

Michter’s US1 Sour Mash is a no-age-statement whiskey, so the length of aging is undisclosed. It’s barreled at 103-proof, but since it’s chill-filtered, it is bottled at 86-proof.

The sweet taste of Michter’s US1 Original Sour Mash whiskey is front and center. While the palate offers plenty of complex flavors, the finish is a bit lackluster.

According to Michter’s, their whiskey has a unique grain selection so it has a significant influence on the flavor of this drink. 

“Washington and his troops drank Michter’s while they were hunkered down in Valley Forge…whiskey connoisseurs are giving it high marks.”

— Maria Puente, Entertainment Reporter

While the label claims that the whiskey’s “sour mash” is rare, the palate is incredibly smooth, and the sweetness is exceptional.

Distillery & Ownership

Michter's Distillery

The owner and distiller of the Michter’s US1 Sour Mash are the Michter’s Distillery itself, located in Louisville, Kentucky. 

Value & Availability

The smooth texture of this whiskey takes it above average value. Despite its enjoyable sweet taste, the overall baseline of this drink could be more impressive. It can be attributed to the whiskey’s lackluster finish.

This is produced in limited quantities, so it’s not widely available in liquor stores.

How to Drink It

There’s no such “right way” to drink whiskey; it all depends on your style and preference.

But with Michter’s sour mash, we suggest mixing it with Coke over ice or just on the rocks.

Compared to Other Whiskeys 

George Dickel Recipe No. 8 Classic Tennessee Sour Mash

George Dickel No. 8 is cheaper than Michter’s, but considering the alcohol content, Michter’s is quite higher at 43% ABV compared to GD’s 40% ABV. 

On the tasting notes, they’re almost comparable. The cherry, cinnamon, and butterscotch notes are noticeable in both spirits.  

Belle Meade Sour Mash Straight Bourbon

Belle Meade and Michter’s are within the same price range, but the former is higher in proof (at 45% ABV) than the latter (at 43% ABV). 

If you’re a rye fan, you’ll like Belle Meade better than Michter’s. But if you’re on the sweet and spicy side, Michter’s is way better. 

Colonel E. H. Taylor, Jr. Old Fashioned Sour Mash Bib Bourbon

Colonel E.H. is more high-proof and pricey compared to Michter’s. But the high ABV of Colonel’s justifies the price point. 

You would prefer Colonel than Michter’s if you’re into high-proof whiskeys with a little heat. But if you’re a beginner, then Michter’s is much better. It could be stronger and more complex.   


Why is Michter’s sour mash not bourbon?

Michter’s sour mash isn’t bourbon, probably because it’s not made with at least 51% corn, which is the percentage required for a spirit to be called “bourbon.” [2]

Michter’s didn’t disclose the mash bill of their sour mash, but as per the website, the mash contains a fair amount of rye in addition to a fair amount of corn and a little barley. 

Is Michter’s US-1 Sour Mash Whiskey hard to find?

Michter’s US-1 sour mash whiskey is hard to find nowadays. It is getting rare since it was produced in small batches, so there are only limited quantities. 

Is Michter’s sour mash allocated? 

Michter’s sour mash is now subject to allocation because the demand is way more than the supply. 

Final Thoughts

Michter’s US1 Sour Mash Whiskey is an average smooth and sweet whiskey. Nothing really special in this spirit; it’s just your typical sour mash whiskey. 

The only edge here is it’s like an old-fashioned whiskey, where you can keep returning to the old-day whiskeys—smooth, creamy, and sweet. 

It’s disappointing that the finish of this whiskey is so lackluster, as it offers so much in its own right.

However, it still remains a delightful whiskey that anyone can enjoy (minus the high expectations).
