Costco’s Kirkland Signature bourbon lineup is showing unusual price stability in 2026. Several bottles that attracted attention when the Kentucky bourbon range debuted in 2021 are still selling for only a few dollars more at reported warehouse prices five years later.
The trend is clearest with Small Batch, Bottled-in-Bond and Single Barrel. Prices vary by warehouse, taxes and state alcohol rules, but the reported changes remain modest — an important detail for shoppers comparing bourbon value at Costco.
Costco Kirkland bourbon prices in 2021 vs. 2026
Kirkland Signature Small Batch was reported at about $19 in 2019. In 2026, the 1-liter bottle was spotted for $20.79 at a Los Angeles Costco. That is only $1.79 more, and the cited comparison put the price roughly $4 below where it would have been if it had simply kept pace with inflation.
Bottled-in-Bond was around $25 in August 2021 and was reported at $27.49 in July 2026. Single Barrel changed even less in the cited examples, moving from $29.99 in December 2021 to about $30.58 in 2026.
| Bourbon | Earlier Price | 2026 Price | Change |
|---|---|---|---|
| Small Batch | $19 (2019) | $20.79 | +$1.79 |
| Bottled-in-Bond | $25 (2021) | $27.49 | +$2.49 |
| Single Barrel | $29.99 (2021) | $30.58 | +$0.59 |
These are location-specific warehouse examples rather than guaranteed nationwide prices. Costco prices and liquor inventory can differ between stores, making a local price check important before making a special trip.
Who makes Costco’s Kirkland bourbon?
The original Small Batch, Bottled-in-Bond and Single Barrel trio debuted in 2021 with production tied to Barton 1792 Distillery in Bardstown, Kentucky.
The official Barton 1792 Distillery website says the distillery was established in 1879 and operates on 196 acres in Bardstown, with 29 barrel-aging warehouses. That established Kentucky production background is part of what made the Kirkland releases noteworthy beyond their low prices.
Costco’s private-label strategy also fits its wider focus on value and product discovery. That shopping model can be seen in how Costco’s free samples influence product discovery and purchasing decisions, particularly when members encounter products they had not planned to buy.
A new 1.75-liter Kirkland bourbon adds another option
Costco’s bourbon selection expanded in 2026 with a Kirkland Signature Kentucky Straight Bourbon Whiskey in a larger 1.75-liter bottle. It was spotted for $28.49 at one warehouse, making bottle size an important part of the value comparison.
The newer expression should not automatically be attributed to Barton 1792. Its precise supplier has not been definitively disclosed, so assigning a distillery based on shopper speculation would go beyond the confirmed information.
Costco also stocks established bourbon brands. Reported 2026 examples included a 1.75-liter Elijah Craig Bourbon Whiskey at $28.47 and a 750-milliliter Angel’s Envy Kentucky bourbon at $43.19. As with Kirkland products, prices and availability can differ by warehouse.
That changing inventory is part of the broader warehouse shopping experience, where Costco warehouse deals can vary by location and disappear as inventory changes.
What shoppers should know before buying
Not every Costco warehouse sells liquor because alcohol laws differ by state. Even locations permitted to sell spirits may not carry every Kirkland bourbon at the same time, and warehouse prices can differ from online or delivery pricing.
Bottle size matters too. The original Kirkland bourbon releases come in 1-liter bottles, while the newer Kentucky Straight Bourbon uses a 1.75-liter format. Comparing the cost per liter can therefore give shoppers a more useful measure of value than the shelf price alone.
The five-year numbers remain striking: Bottled-in-Bond added just $2.49 between the cited 2021 and 2026 prices, while Single Barrel moved only 59 cents. For Costco members who can find the bottles locally, Kirkland bourbon remains remarkably close to its earlier price range.
