Kirkland Signature Islay Single Malt Scotch Whisky Review & Tasting Notes



If you're a Costco member, you've undoubtedly been to the liquor section of your local club to see what they have. And, you've likely stumbled across its Kirkland store-brand whiskeys and wondered to yourself, Can this be any good? Especially at that price? I know that thought has crossed my mind whenever I've perused the aisle.


Lately, I've been on a Scotch kick. I go through these cycles. Sometimes it is Bourbon, sometimes Rye, sometimes Irish, and for whatever reason, I gravitate toward them. I lost my whiskey virginity to Scotch, so it holds a special place in my heart. On the flip side of the coin, I'm not a wealthy man, and Scotch is an expensive part of an already expensive whiskey hobby.


A few months ago, I saw rumblings of Kirkland Signature Islay Single Malt Scotch hit the interwebs. There was a lot of excitement, and, as with anything, many naysayers who said an Islay single malt for $39.99 will taste like garbage. The #DrinkCurious lifestyle told me that's hogwash. After just enjoying a $38.00 bottle of Ardbeg Wee Beastie, I know good Scotch doesn't require a loan.


One of the frustrating things about buying Kirkland whiskeys is you have no idea where it comes from because they are very tight-lipped about it. However, Islay only has nine working distilleries and since this is a single malt, we know that means it isn't a blend of several. That's the first piece of the puzzle.


Other information we know is that it comes from Alexander Murray Co., which is an independent bottler. Independent bottling is pretty easy to explain. Distilleries have thousands of casks doing nothing but aging to perfection. An independent bottler selects casks they find special and bottles them on its own. There exist some superstar independent bottlers, and there are those who are mediocre at best.


This Kirkland whisky carries no age statement and is bottled at 100°. I picked up my bottle for $39.99.  I'm sure different distribution territories have different prices. But the key here is this is very affordable. And, that ponies up the second and third pieces of the puzzle.


Appearance:  Poured neat in my Glencairn glass, this Scotch was golden in color. The bottle suggests nothing regarding added caramel coloring or chill filtering. But, at 100° would negate the need for chill filtering. The rim was wide and yielded fat, fast legs that crashed back into the pool. 


Nose:  Peat was expected and it did not disappoint. That's the first note I picked up from the moment I poured my first glass.  Brine, citrus, barbeque smoke, and vanilla each held their places. When I breathed the aroma into my mouth, I tasted lemon curd rolling across my tongue.


Palate:  There was no mistaking the mouthfeel for anything but being full-bodied and viscous. On the front of my palate, I found smoked vanilla and pear. As it moved to the middle, flavors of salted caramel, ginger, and citrus were evident. The back offered marmalade, tobacco leaf, clove, and (again) ginger. 


Finish: Long-lasting but not overpowering, the finish features barbeque smoke, vanilla, clove, tobacco leaf, and freshly-cracked peppercorn. The smoke sticks around for the whole shebang.


Bottle, Bar, or Bust:  Buying a bottle of Kirkland Signature Islay Single Malt Scotch for only $39.99 should be illegal. This can stand shoulder-to-shoulder with so many lovely Scotches and beat them on price. If peat is your thing, this will be, too. This may be one of the easiest Bottle ratings I've conveyed in a long time. I don't know how else to say this:  Buy it (and please, ye kind whiskey gods, let this be a permanent offering).


Final Note:  We've had three pieces of the puzzle that offer a hint to this whisky's origin. The tasting notes offer a few more. It is fairly obvious this is a heavily-peated Scotch. That barbeque quality from the nose and finish is also a clue. I can't swear to it, and this is purely a deductive guess, but I'm going to go out on a limb and say a 100°, heavily-peated Islay Scotch that is very easy on the wallet would be Port Charlotte out of the Bruichladdich distillery. Cheers!

  2. Just tried a glass tonight. Definately the first thing was the smoky aroma as you tilt the glass.

    1. The flavor was that of a whiskey aged too long in charred barrels, inside a charred warehouse, in the middle of a charred forest. The aroma alone is enough to give a California firefighter on-the-job flashbacks. Not recommended for anyone trying to quit smoking.

  3. Absolutely sublime. I have spent more money on lesser scotch. Be careful, the robust flavor buries the 100 proof so it sneaks up on you!

  4. I wish I could find it that cheap! $58.99 here in Puerto Rico

    1. I’m from PR too. As a cocktail enthusiast I can tell you this is probably one of the best peated scotch you will find for that price. In US you can find Laphroig for about $40-45 but you have to pay for the travel and pay for your bags. In PR I have not seen yet any distributor with some recognized brand of peated scotch and I’m sure if some one brings it it wold be over $70 with the tax and all the cost related to. So I think this one is a decent and value peted scotch here in PR.

    2. It is a seasonal outturn and I was able to scoop this up in new england at 34.99 if it really is Laddie then its they buy of the century. Heck, if its Coal ila or bowmore it still is...

  5. Here in Korea, It's about 80$. (F***ing Tax.....)

    ReplyDelete
  6. Just purchased in Costco Korea and it was almost $75 due to the import tax I think. Still 'Bottle' rate with this price? Haven't opened the cap yet and will compared to Laphroaig 12yrs that is similar price range in here..

    1. Hard to say because I don't know what other comparable whiskies would cost there. As an example, I can pick up Ardbeg Wee Beastie for $40.

    2. In canada Wee Beastie is 95 bucks that sucks

    3. In Alberta you can sometimes find the Wee Beastie on sale for C$60 and less. I bought mine for $59.99 + gst.

  7. New to scotch. Trying to enjoy it. Four of us newbies tried it. We all agreed it smelled either like nail polish or a nail salon. Did not really enjoy the taste either.

    1. Sugar Ray, thanks for writing. For those who are new to Scotch, I try to steer them away from those from the Islay region. Very few new Scotch drinkers would appreciate it. Peat is something you have to grow into, starting subtly and then moving into deeper expressions until you find your sweet spot. My recommendation would be to start in Speyside and then move to Highland, then start exploring the others from there. Cheers!

    2. Hi Sugar Ray! If new to scotch and at Costco, please try Aberlour. Another great buy and completely different scotch.

      Delete
    3. When family or friends ask me about trying scotch for the first time, I usually steer them to a blended scotch (Chivas Regal) it’s much easier on a new palat. Once you’ve acquired a taste for that, start trying others.

  8. How does this compare to Laphroig 10 year?

  10. Great review. Thanks.

  11. Thanks for the review, which I hadn't read til after I bought a bottle and had a taste. I agree - it's a darn good, peaty Islay!

  12. I just tried a bottle last night and this Costco Scotch was terrific! The first thing I said was it tasted like a much more expensive Aardbeg. I'm going back today and pick up a case. This is a keeper. And if other people don't like it, that's ok. More for me!

    ReplyDelete
  13. Damn if that doesn’t taste like Laphroaig 10. Very solid for the price.

    ReplyDelete
  14. Just tried it. My guess is that it’s closer to an Ardbeg Corryvreckan than Port Charlotte (which I had side by side with this Kirkland one)

    ReplyDelete
  15. Paid 60 after uncle Sam’s share in MI. While peaty is my alter ego this is for serious peaty peeps. It was surprisingly a lil sweet ; May be the 50 abv lol. But deffo on the lines betweeen the laphroig n brucchladich by palette w/o adding water. It opened up quite staying for a while - bringing earthiness, ginger a bit of sea water to the nose. Was quite a good break from my regular taste of the Spey side/ Macallan likes

  16. Just did a side by side comparison of the Costco Islay bought today with Ardbeg An Oa bought there some months ago neat, watered and then iced and I really can't tell the difference.

    ReplyDelete
  17. Just picked it up here in Michigan for $54.39 (+6% tax). Not as peaty as the Port Charlotte from Bruichladdich, but could still very well be a Port Charlotte. My first thought was towards Ardbeg though. Will have to do some comparison testing tonight. Lovely sweet peatiness.
    (Also got a Viking Pride for $59.99 which isn't too bad. My Viking forefathers would be proud of)

  18. Got a bottle at Costco in Waltham, MA for $34.99 today and tasted some immediately after getting back home. I am the first time buyer of a Kirkland brand whisky. What can I say… wow, I am very impressed by the quality and the taste of this scotch! It certainly didn’t disappoint. Many thanks for this review! Good to know what you are drinking!

  19. Just tried the Scotch. I was a little disappointed....too much peat. I am not a Laphraog kind of guy.
    I was hoping for more of a Lagavullin taste. But I should have realized it wouldn't be that quality for this price of $38. I put an ice cube in it and it mellowed out the peat a little bit. This is not as good as the Islay they had a couple of years ago. Personally I think they snatched this from the Laphraog distillery.

    I have been a single Islay peat scotch lover for 50 years. I must have at least a dozen in my cabinet. I picked up a bottle of this at Costco yesterday and it is equal to or better than my $80 - $125 bottles in my collection. I would bet on Port Charlotte or Laphroig as the source, and I plan to keep a couple bottles on-hand in case my local Costco stops selling it. Great review!

  21. Just got a bottle for my birthday and tried it with ftiends. The first thought that hit my mind on first taste was Caol Ila 12. I can see the Bruichladdich Port Charlotte as a possibility though too with its saline and slightly sweet notes.

  22. According to the review I went out and made the purchase which I wish I hadn't. Awful, absolutely taste like gasoline. My throat is burning on fire. Not for me. I was going to return to costco, decided to keep and share amongst my friends. Whichever friend enjoy it, Christmas comes early for them.

    2. I guess not. I drank neat . Once I added ice it was not so bad. I'll stay with Glen Moray 18, Oban etc

  23. I'm gonna get one tomorrow and try it out with my scotch drinking buddy brother in law

  24. I recently bought a bottle in South Florida for $35. I usually drink very expensive scotch, such as 16 yr. Lagavulin (now selling for over $120) or an aged Ardbeg. I think this "mystery" single malt scotch from Islay sold by Costco is incredibly good, and it could be one of the Ardbegs.

  25. I like peat and love the burn just straight.I normally go for an Ardberg but came across this today before I saw the review.Great price great burn I liked it as much as the Ardberg if your not tried or into peat this is not for you.I will buy again

  26. I have been enjoying full flavored peated scotch for many years. I have tried about every peated scotch available here in my local market area and will say, without hesitation, the kirkland Islay can stand toe-to-toe with the most popular 10-year Ardbeg, Laphroaig, Port Charlotte, and Lagavulin. However, as with all of them, they fall a bit short of my favorite, Lagavulin 16 which is the smoothest and least intrusive to the pallet and follows with a mild and moderately lingering smoke. Perfection, in my opinion, for a cost of $120.00 here in my area.

    ReplyDelete
  27. I prefer heavily peated whiskeys. I have Laphroaig 10, Ardbeg 10, Lagavulin 16 on hand and this is hands down the better of them all. You can see it's non-chill filtered by the way it clouds up with the addition of a little water. You can't go wrong at $37 for a non-chill filtered (and no color added) Scotch. I absolutely love the finish. Clean and smooth with warm vanilla notes and subtle celery. My only regret is I didn't buy more.

  28. I’m a total newby to bourbon, whiskey, and scotch. My very first bottle of scotch was the Kirkland blended scotch. First reaction was that it tasted like smoked cigarettes in an ashtray. But, I quickly began to appreciate it. Just bought this one, and it smacked me hard. Mmmmmm. Guess I’m a fan and feel lucky to have tried it.

  29. Having had bought a couple of bottles in the past and enjoying them (to me, very similar to PC10), I was pleased when it was back on the shelves at the Costco store here in Edmonton. Such a disappointment... I realize that there are variations with different batches of distillation, but this product is completely different from what I remember it to be. If I was able to, I'd return it to Costco and pay the extra money for a bottle of Lagavulin 8. And in my opinion, it's been chill-filtered and coloured.

  30. Almost August 2023 picked up a bottle today and have no idea where these good reviews from a couple years ago would stand today. I love Islays, know them,but wouldn’t recommend this one. Wish I had tried a couple years ago.....

  31. As a fan of Islay Scotch I made a point of visiting the lovely island on my last trip to Scotland. Peat was an acquired taste I learned from my father. As a young adult new to Scotch the first sample he offered created a sour face and he had to finish the glass. As my tastes matured I learned to love the peaty Islay Scotches to the point they are now preferred over most others. Over the years I've had a number of Islay Scotch in my cabinet. I last bought this Kirkland brand in Central Florida for $35 August 2023 having bought it before. My favorite single malt is Lagavulin 16 which is akin to mother's milk but as the price has risen over the years I've not always been able to justify it. For the price this Kirkland bottle is fantastic value. My limited pallete likens it to Laphroaig 10 but I readily accept other opinions. Which distillery it's from doesn't matter to me as Islay is a small island. It may not be my favorite but for the price it's always good to have a bottle on hand.

  32. I'm seeing a lot of mixed reviews here but seems like a great buy among the crowd here. Clearly, it's either gonna be love it or hate it. I bought as a gift so I can't wait to not only try it, but also return with taste results. I know what to expect and can relay this to the receiver. I saw a couple grab two bottles ($36ea) b/c it wasn't in stock previously.

    1. I came back to say this was GREAT! My own thoughts as I took the first sip: full-bodied strength, nice flavor. It is robust and deeply warm as a well oiled furnace, and I loved it. My brother said it must have been aged pretty lengthy because it was as smooth. When other folks above described this as cigarette ash, they either had a really bad batch or just aren't scotch drinkers! I attended a tasting years ago and tried a Macallan 17 that tasted every bit of the burnt oak cask that left it tasting charred. I didn't know peaty was the word for what I simply called "smoky and oaky", and I didn't care for that version. This Islay is so much nicer.

  33. I am fine with “peaty” scotches, and was really looking forward to my first taste. I took a sniff test after uncorking and was appalled by the chemical odor. It didn’t get better on tasting (neat). My wife went searching for the source of a smell and I said, “here sniff this”. And she recoiled. Yup. I’m chalking up to a bad batch. Buyer beware.
