From the extensive selection of spirits to their in-house private-label selection, Costco has enough to keep even the most discerning drinker happy. Not all bottles are winners, however some are steals, and others may have you regretting the buy.

The Kirkland Signature Speyside 20-year-old Sherry Finish Single Malt Scotch stands out, frequently referred to as the jewel of Costco’s liquor catalog. Single malts that are aged tend to be scarce and expensive due to the “angel’s share” the liquid that evaporates over time.

It wins blind tastings, such as one conducted by The Kitchn’s expert group, against heavy-hitters like Grey Goose due to its crisp, subtly sweet taste. It is thought by many to be made in the same Cognac area and use the same pure Gensac Spring water as Grey Goose, making it crisp and delicate.
At about $23, it’s a fraction of the price of high-end vodkas sometimes a third as much as Grey Goose for the same amount. Drink it neat, over ice, or mix it into your go-to cocktails. Be sure to pick up the red-label version, which indicates the coveted French variety.

For those who like a richer, smoother tequila, the Kirkland Signature Tequila Añejo is a great discovery. At roughly $30 for a 1-liter bottle, it delivers the oaky richness of upmarket brands such as Don Julio or Patrón.

This ready-mixed beverage is a gem in the burgeoning ready-to-drink (RTD) market, which was the leading alcohol category in 2021.

Kirkland Signature Liquors to Avoid

6. Kirkland Signature Spiced Rum
Spiced rum evokes tropical flavors and strong personalities, but the Kirkland Signature Spiced Rum leaves consumers desiring more. Priced at approximately $20 for a 1.75-liter bottle, it’s affordable, but short on depth compared to Captain Morgan or Sailor Jerry. Spiced rum typically employs herbs and spices aged in oak barrels, but Kirkland’s version, marked “rum with natural flavors,” introduces flavorings and caramel color, which has the taste of taking a shortcut.
- Current Reviews Indication: Reviews from 2020 Reddit discussions highlight a formula change in the spiced rum.
- Unpleasant Undertones: The new formula introduces off-putting flavors described as charcoal, tobacco, and ash.
- Impact on Enjoyment: These artificial “fake flavors” make the rum difficult to enjoy, whether in cocktails or neat.
- Alternative Use Suggestion: It may perform better in cooking applications, such as a spiced rum cake.
- Overall Recommendation: As a beverage, it’s not the best option; consider trying other rums with natural spice blends for a more pleasant experience.
The batches can be inconsistent, so it can be a risk, and even in cocktails, the odd aftertaste can mess with things. You’re best off paying a little more for a rum that gives you the rich, lively flavors you want.

7. Kirkland Signature Irish Whiskey
Irish whiskey has a reputation for being smooth, warm-tasting, but this Kirkland Signature Irish Whiskey doesn’t live up to it. It complies with Ireland’s regulations aged three years in oak casks but lags behind Jameson brands. Recent reviews complain of a fierce alcoholic sting and watery body, lacking the honey, vanilla, and spice that characterize fine Irish whiskey.
- 2019 Review: Wine Enthusiast tasting in 2019 labeled it a good buy.
- Recent Commentary: Notes flavors of dried fruit, spice, and caramel, but these are overshadowed by raw booze.
- Unpleasant Experience: The harsh burn makes it unenjoyable neat or in cocktails like Irish coffee, where it overpowers other flavors.
- Recommendation: Spending more for a refined brand is advised for a smoother drinking experience.
It may be acceptable in simple mixed drinks, but high-end brands are worth it for fuller flavor. The fact that it is not deep makes it a hard sell to whiskey enthusiasts who desire a rich, rounded experience.
8. Kirkland Signature American Vodka
The Kirkland Signature American Vodka falls short of the French edition’s expectations. Available for around $17 in a 1.75-liter bottle, it is distilled six times from California corn and destined for a silky finish. But tasters, including our panel at The Kitchn, described it as bland, watery, and cutting, with strange flavors such as vitamins or chemicals.
- Cocktail Suitability: Suitable for highly flavored cocktails where the vodka flavor is masked.
- Performance Limitation: Falls short in cocktails where vodka is the primary flavor.
- Comparison to French Vodka: French Vodka offers better quality for a slightly higher price, providing a smoother, more pleasant drink.
- Recommendation: Not ideal for those seeking a refined, classy vodka experience; considered a skip.
Even in punches, its harsh edges can be obtrusive. For neat, clean vodka cocktails, opt for products that eschew these unpleasant notes and provide a smoother finish.

9. Kirkland Signature Silver Tequila
Whereas the Kirkland Signature Tequila Añejo pleases, the Silver Tequila is a letdown. Created from 100% blue agave and double-distilled, it ought to be silky, but most find it has a harsh, vegetal, and medicinal sting. Fine silver tequilas provide clear agave, floral, and peppery qualities, but this one’s alcoholic sting dominates.
- Price Appeal: Attractive due to its low cost.
- Quality Shortcoming: Lacks the quality needed for sipping or margaritas.
- Comparison to Alternatives: A superior silver tequila offers a brighter, crisper flavor.
- Value Recommendation: Worth spending extra for a better tequila.
- Final Verdict: Best left on the shelf due to its inferior quality.
In cocktails or shots, the bitterness can destroy the atmosphere. For a good, delicious tequila experience, choose a smoother version that provides quality and enjoyment.
Final Thoughts
Costco’s booze aisle is a treasure trove and pitfall. Let this guide walk you through it, from the amazing Speyside Scotch to the disappointing Silver Tequila. Avoid the losers and stick with the best for fantastic taste and value. Shop wisely, sip blissfully, and cheers to excellent finds!
