Isaac Bowman Port Barrel Finished

Are we finished with finishes?

Definitely not, if current trends are any indication. While cask finishes may be old hat to the Scotch whisky aficionados in our audience, they remain a novelty in the land of American whiskey. However, it’s a growing market; a quick search for finished bourbon at my local liquor superstore reveals not less than two dozen products on the shelf. These have been finished in casks ranging from Amaro to XO Cognac, with many exotic options in between.

Perhaps the most successful experiment I have yet encountered with the technique came in the form of Wild Turkey’s Revival expression. They’re not all winners, though. Jason was less than enamored with Legent, Beam Suntory’s trans-Pacific dalliance with blending and finishing. Finishing also exists as a way of dressing up some sourced bourbon for resale at a premium, as in the cases of Angel’s Envy and Blood Oath. Furthermore, finishing can be used to turbocharge the flavor on otherwise innocuous bourbon.

In all, I’d describe myself as skeptical but hopeful when encountering a bourbon with a cask finish. I’m more encouraged when the finish was applied (is this the correct verb?) by the people who made the whiskey in the first place. After all, they’re probably less likely to monkey disrespectfully with something they themselves created, right? We’re about to test that hypothesis… or will we?

The subject of today’s review comes to us from the A. Smith Bowman distillery of Fairfax County, Virginia. This distillery was started by farmer (you guessed it!) A. Smith Bowman in 1934 as an outlet for the surplus grain from his 7,200 acre farm. As the sole legal distillery in Virginia until 1950, Bowman was best known for its Virginia Gentleman brand.

Virginia Gentleman is somewhat of an oddity. The Bowmans sourced the distillate for the brand from Kentucky, but it was re-distilled and matured in Virginia. A peculiarity of the maturation process entailed the barrels being stored vertically on their end, rather than horizontally on their side, as is the custom in Kentucky.

1988 saw the relocation of the distillery off the Bowman farm and into a former industrial plant in its current home of Fredericksburg. Though no mention is made of the relationship on Bowman’s website, a little internet searching reveals that Buffalo Trace parent Sazerac has owned the distillery since 2003. It was reported at the time that Buffalo Trace was also a source of the distillate for re-distillation.

So, is this still the setup? It will come as no surprise to our loyal readers that there’s a whole lot of ambiguity around the specifics about what is produced where. The company’s site mentions fermentation and stills, but it’s not clear how much of whatever Bowman is producing is distilled on-site. Current Master Distiller Brian Prewitt joined the team in 2013; I was able to connect with him via a PR intermediary. He answered some (but not all) of my questions, below:

Malt: Please describe Bowman’s current production process for whiskey?
Brian: Our recipes, fermentation profiles and distillation profiles are proprietary. However, some details that we do share are as follows: Our fermentations generally take less than a week depending upon the recipe, the majority of our whiskies are triple distilled to a 140 to 150 proof range but some are only double distilled. We typically use 53 gallon charred (#3 to #4) white oak barrels from EBC at the current time, but also use barrels from several different coopers and several different wood types and origins as well as many char/toast levels.

Malt: What is the annual output of the Bowman distillery?
Brian: We do not discuss production numbers, but we produce less in a year than some larger distilleries can produce in a month or even a week.

Malt: Is Virginia Gentleman whiskey still produced at the Fredericksburg distillery?
Brian: Yes, we still produce Virginia Gentleman Bourbon.

Malt: I had read that distillate from Kentucky was historically re-distilled in Virginia by Bowman to produce whiskeys. Is this still the case?
Brian declined to answer this question.

Malt: If so, is this distillate currently coming from Buffalo Trace?
Brian declined to answer this question.

Malt: Any other comments about the relationship between Bowman and Buffalo Trace?
Brian: As a sister distillery that is currently owned by the same family that owns A. Smith Bowman Distillery, we have a very close relationship with all of the other distilleries in the Sazerac portfolio.

Malt: Where do the port barrels for finishing Isaac Bowman whiskey come from?
Brian: Most of our port barrels for Isaac Bowman are used Ruby Port barrels that we import from Portugal.

Malt: For how long is Isaac Bowman whiskey typically matured? For how long is it finished?
Brian: We currently age the base bourbon for Isaac Bowman anywhere from 4 to 6 years in a new charred oak barrel and finish in port barrels from 3 – 6 months or longer. We then blend the different port barrel finishes together and mingle them together in a 6,000 gallon white oak Foeder which we use as a modified Solara process. Bottling blends are pulled from this tank and new blends are pumped on top so that the new lots are mingled with the previous lots. The tank is not allowed to be emptied more than half way before being topped with a new blend.

Thanks to Brian for the information he was able to provide.

Back to Bowman: the range currently encompasses Bowman Brothers (a small batch bourbon) and John J. Bowman (a single barrel expression). Experimental infused and finished bourbons are released in limited editions under the Abraham Bowman name. The whiskey we’ll be considering today is “Virginia straight bourbon whiskey” finished in a port barrel (“many of which come from Virginia wineries,” per the site, and in contrast to what we heard from Brian). It is called Isaac Bowman, for the Revolutionary War officer and brother of Abraham.

This Isaac Bowman expression comes to us at 92 proof (46% ABV). SRP, according to Bowman, is $40. This was a sample generously provided by Will, who once again has my sincere and heartfelt thanks. You can purchase a bottle from Shared Pour for $49.99.

Isaac Bowman Port Barrel Finished – Review

Color: Rusty brownish-orange.

On the nose: The port barrel influence is immediately noticeable in the form of a heady, winey aroma that leaps out of the glass and completely dominates the nose initially. Some time in the glass reveals a roasty whiff of mocha, some stewed apples, a sprinkling of ground cinnamon, and the rubbery scent of balloons fresh from the bag. This is fruity in a plump and pleasant way, but I’m struggling to cut through that dense and intense overlay to get at the underlying whiskey. Let’s see if that changes on the palate?

In the mouth: Indeed, this is more balanced through the mouth, where the port barrel plays a supporting role rather than being the lead. The initial impression is of a salty and meaty nuttiness, in the manner of cashews. I’m tasting a bit of a dried firewood type of flavor before this once again broadens out in the middle of the mouth with a burst of sour cherries and underripe plums. These fruity notes linger in somewhat acidic and tart form, which I actually find an improvement over the sticky sweetness implied on the nose. The finish is long, with a gradual pulsating re-emergence of the sweeter and richer fruit elements.


This delivers a few of the same points of intrigue as Revival. It doesn’t quite have the same breadth of flavors, particularly the savory and spicy notes that so deftly counterbalanced the sweet fruit and wine elements in that case. This whiskey is a fair deal less expensive, though, so I am reluctant to penalize it too much. I’m knocking a point off the score that I gave to Revival, which still leaves this in very solid territory on the Malt scoring framework. On net, I’d recommend this to anyone curious about how a wine cask finish can be successfully applied to a bourbon whiskey, regardless of its origin.

Score: 6/10

    I always enjoy it when you get in contact with people from the distillery, Taylor. It continues to confound me how few details about the process are available to the public with regard to some of the country’s best bourbon. Keep uncovering these details whenever possible!

    As for the review itself I tend to agree with you that this is a solid pour, though I prefer the single barrel Bowman offers. Any chance of you reviewing that soon, or can we expect you to continue on your finished whiskey kick?

    1. Taylor says:

      Frank, very kind of you to say. It is frustrating for me as well. Regardless, I am going to continue asking the pointed questions and making note of when they are not answered satisfactorily. I would be open to trying a Bowman single barrel, should someone offer me a sample. As it is, the backlog is long enough! Cheers!

  2. John says:

    Bourbon finished in amaro casks? Do share the name of this one.

    For some reason I used to get this mixed with the 1793 brand. Thanks for the interview.
    It’s uncommon see read a bourbon get triple distilled. I wonder why they do this.
    Any idea what size the port barrels are?

  3. Mike says:

    I’m a year late to this party, but for what it’s worth:

    I’ve just returned stateside from overseas in the last few months, and local scotch prices drove me back into the arms of bourbon. Fortunately, I’m in Northern Virginia and have access to several very solid Virginia distilleries (Bowman, Catoctin Creak, etc.). In November I took a few friends down to Fredericksburg to tour the grounds and do the tasting, at which time I asked about the questions the master distiller was hesitant to answer herein.

    According to our guide, in the past Buffalo Trace did make some distillate for Bowman, but it was per Bowman’s mash bill recipe and was due to capacity limitations during their factory move and as they upscaled production. He said that at no time to his knowledge was Bowman bourbon based on Buffalo Trace mash bill, rather Buffalo Trace helped produce their mash bill to their recipe. Further, he said they haven’t done this for some time as they’ve upped their production capabilities.

    Our guide, a super nice young named Micah, was both enthusiastic to answer and also visibly annoyed that Buffalo Trace mash bill myth lives in perpetuity. Though, I can’t help but find the fault on part of Bowman, as they haven’t directly, publicly clarified in black and white.


    1. Mike says:

      A clarification:

      By “… Buffalo Trace helped produce their mash bill to their recipe,” I mean Buffalo Trace produced some mash bill for Bowman according to Bowman’s recipe/specifications.

      And a correction:

      *super nice young [guy] named Micah

      1. Taylor says:

        Great color Mike, thanks for sharing. I’m always happy to hear the “off-the-record” view of friendly tour guides or distillery employees who want to set things straight, so I appreciate you passing this info along. Cheers!

    The Bowman distillery is in the city of Fredericksburg, which is NOT in Fairfax County, VA. Fredericksburg (my home town) is not in any county. It’s independent. And Bowman, contrary to these comments, does import Buffalo Trace’s Eagle Rare mash bill (not Buffalo Trace) and puts it through their own process. Just as proof, they produce an OUTSTANDING bourbon cream called Mary Hite Bowman bourbon cream, which is sold in the SAME bottle as Buffalo Trace’s bourbon cream but adds a delicious caramel to the mix that makes it far superior. So they doth protest too much when it comes to their relationship with BT. The Bowman distillery’s main product is the very, very, very cheap bourbon called Virginia Gentleman, which is really quite good for it’s bargain basement price. But their premium bourbons and annual allocated releases are exceptional and well worth pursuing.
