“Now naturally, like many of us, I have a reluctance to change too much of the old ways.”
–Kazuo Ishiguro
In April of 2026, Michter's quietly expanded their lineup. I have to admit in the bustle of my own life, I missed covering the press release. Perhaps hiding in the shadows of the revered 10 year expressions, a new barrel strength US-1 Kentucky whiskey snuck on the scene and managed to elude my gaze until one fateful day in August sent me down a sour mash rabbit hole...
Sour mash at its core is, of course, just a simple distiller's technique: the process of returning some of the acidic backset from a previous distillation run to regulate pH and protect the yeast on the next fermentation cycle. This genius recycling loop returns a small gravesite of dead yeast cells to the mix, supplying a slurry of nitrogen, lipids, and vitamins to feed the fresh batch of live yeast for the next run. In turn, this methodology also normalizes the flavor profile, producing a consistent and distinct house style for any distillery using the sour mash technique today in American distilling. So how did Michter's manage to turn such a ubiquitous process into a whiskey brand that is uniquely theirs? The truth is the modern brand actually didn't; the prominence of using sour mash as a whiskey style is a historical moniker—and potentially one of the best nods to their rich history yet.
"When Michter's was being produced in the 1970's and the 1980's, the then-Pennsylvania distillery's most popular whiskey was its Sour Mash," said Michter's President Joseph J. Magliocco. "The Michter's US★1 Sour Mash that we make in Kentucky these days is a wonderful whiskey, and we're excited to have this opportunity to share it at barrel strength."
I've had the great fortune of tasting several examples of the old Michter's Pennco sour mash whiskey through the years. The era Joe Magliocco mentioned in the quote above was dominated by decanters, and I've got one of their jug-house white ceramic thumbhole bottles with whiskey still in it on my shelf today—actual Dick Stoll distillate in the famous sour mash, made in their Schaefferstown, Pennsylvania distillery. I'll use this pour as my baseline lens for examining some of the old ways later in this article.
The 70's and 80's were not good years to be producing and attempting to market whiskey, so many brands turned to flashy collectible presentations to try to lure in new markets, even if the purchasers were never going to drink their whiskey. It's through the good fortune that folks didn't listen to the "DRINK NOW. DISPLAY LATER." hang tag from the jug, meaning we still have examples to taste, compare, and learn from today.
When you pore over the details of a bottle of sour mash whiskey, you'll find no note of bourbon or rye. So what gives? It's made pretty much the same way from a mash bill of corn, rye, and malted barley... put in a barrel and aged to the distiller's discretion. It sure sounds like bourbon or rye whiskey to most, but the original Michter's distillery couldn't legally call it either. For the original sour mash jug from Pennsylvania, we have the details preserved from legendary whiskey historians like Sam Komlenic, who confirmed the original mash bill was made from 50% corn, 38% rye, and 12% malted barley. Both bourbon whiskey and rye whiskey require a dominant grain: at least 51% corn for bourbon and 51% rye for the rye designation. This mash bill doesn't get to either threshold, so we end up with just "whiskey." Of course, the marketing wonks couldn't just leave it there, so they advertised their distillation practices by adding sour mash to the title. Knowing that Joe Magliocco was a Michter's fan before he purchased the brand (for a song, mind you), it wouldn't be too far-fetched to believe he chose to replicate that original mash bill today. Since Michter's does not share mash bill information, perhaps we'll never know.
It's also notable that being free from the restrictions of bourbon and rye requiring a new charred oak aging vessel does unlock the possibility that used barrels could be utilized for maturation in this category, though it remains unclear if that practice was used historically or is in practice today outside of the unblended American whiskey label. My expectation and assumption are that only new charred oak barrels are employed for the bottle under review today.
I purchased this bottle with my own money for the purposes of this review, scoring a bottle at one of my local packies for right at the MSRP of $120. I'm tasting again in accordance with my editorial policy, which mandates a minimum of three sober tastings before assigning a formal rating. I have far exceeded that threshold at the time of writing, if that is telling of the quality of the whiskey described below. On with the review!

Nose: A warm wave of butterscotch meets my nostrils as I lift the glass to enter the field of scent view within my glencairn. Returning to my nose augments the initial experience with caramel and milk chocolate again, warm and inviting like a long-time friend who always welcomes you into their home. After a bit of a rest, sticky toffee seeps into every part of my mind. How this manages to be so expressive yet approachable is both impressive and perplexing, as it harkens to a bygone era in American whiskey. On the fringes of long inhales, hints of black pepper and allspice tickle a bit but always return to the uber-rich creaminess of butterscotch and caramel that have defined this pour so far. Those defining characteristics have an amorphous quality to them too. The creaminess ebbs out into new territory, sometimes partnering with a hug of fresh florals and other times resigning to the richness of a chocolate dessert. Overall, I'm thoroughly attentive to the glass, soaking up all it has to offer me.
Coming back from a sip reveals maple candy, potent and level, balanced by the old growth oak reminiscent of some old school bottlings from the late 80s and early 90s—semi-dusties, if you will. It's a captivating nose that has kept me coming back for more over the course of an hour and a half. While the character hasn't shifted drastically, I do occasionally find some new tidbit to adore, as late in the glass beautiful vanilla swings in, taking my mind to a melting Charleston Chew pulled from the freezer on a hot summer day. Maple, caramel, butterscotch, and chocolate are the dominant notes from the nosing experience.
Palate: My first sip is exciting, tantalizing even, as the incredibly expressive nose is matched perfectly on the palate. Leaning a touch more on the chocolate realm, this is an instant classic. Another long sip and swish elevates cherry cordial, a delicate, sensual surprise that somehow fits perfectly with the butterscotch and caramel base. Patient exploration reveals layer after layer of candy sweetness from the Charleston Chew of the nose to the Haribo candy cherries that only the palate seems to propagate. Put just this together and I'm left with a deeply satisfying sipping experience, but I think this glass has secrets yet to tell. While no water was added to the final batch, being bottled at full barrel strength as the label foretold feels like this is proofed just right. No ethanol heat flares up through my nostrils, burns in my chest, or creeps through my esophagus. It's the picture of balance, an oil painting layered with flavor. Sipping near the bottom of the glass continues to produce a viscous mouthfeel covered in flan and birthday cake tones. Add in a sprinkle of cinnamon on the linger, and I'm swooning at every taste. It's a deliciously juicy and round sip, never sharp or bitter. At glass-end, I find a fully captivating experience reminiscent of the entire duration of my pour, like passing the final test that required months of training. It's a victory lap with a finish that celebrates accordingly without becoming too boisterous. Hershey's chocolate, maraschino cherry, amaretto, and caramel smolder long after the sip has gone.
Empty glencairn aromas: Creamy cappuccino, nutmeg, and dulce de leche. Yum.
TL;DR: A butterscotch and chocolate bomb, a taste that matches the old ways of whiskey
Rating: 4.5/5
The comfort and delight in this pour cannot be understated. For me, it transported me to my good friend Jon Cecil's speakeasy, with both the cordial nature of the host alongside the damn good vintage whiskey that inevitably gets shared, giving off an ease that feels like family. While the Michter's whiskey today is notably different than the Pennsylvania whiskey of years past, that has to be expected. The yeasts are different, and the wood is different, but the process remains the same. This new expression is a wonderful nod to the rich history of producing sour mash whiskey and will certainly have a place in my whiskey study for years to come.
