Shoppers appreciate Costco for its remarkable deals, particularly in its spirits section, highlighted by an impressive selection of whiskies. Whether you’re a fan of Scotch and Japanese whisky or the "e" varieties from America and Ireland, Costco offers an extensive array of bottles catering to diverse palates.

As a long-time bartender and whisky enthusiast, I found myself pondering whether Costco is indeed the ideal destination for purchasing whisky. The retailer certainly stocks a well-curated selection, including larger bottles that are often difficult to find in regular liquor stores. This led me to investigate whether the prices merit a special trip and identify which brands are worth purchasing.

Using my Costco membership and experience in alcohol sales, I set out to determine which whiskies are the best buys. Below, I list six brands to consider and six to pass on during your next Costco visit.

Best Values

1. Kirkland Signature: Costco’s own brand, Kirkland, provides excellent value, offering whiskies that are often compared to iconic brands like Crown Royal and Jameson. Its Scotch selections are particularly notable, giving whisky lovers a wallet-friendly way to explore various styles.

2. Johnnie Walker: As one of the most recognized Scotch brands globally, Johnnie Walker offers a variety of blends that are well-priced at Costco, making it an excellent stop for fans of this iconic whisky.

3. Glengoyne: This single malt Scotch is not only competitively priced but also well-regarded for its flavor profile. The 10-year-aged version is particularly appealing for those new to single malts.

4. Four Roses: Renowned for its exceptional bourbon quality, Four Roses is competitively priced at Costco, outperforming many competitors for value and taste.

5. Buffalo Trace: Known for its high-quality bourbon, Buffalo Trace’s pricing at Costco is lower compared to many other retailers, reinforcing its place as a top choice.

6. Sazerac: This rye whiskey is celebrated for its flavor and complexity. At Costco, it’s frequently available at prices lower than other stores, making it a prime choice for both sipping and mixing.

Worst Values

1. Jameson: While popular, this Irish whiskey is easily found elsewhere at similar or even lower prices. There’s little incentive to make a special trip to Costco for it.

2. Mars Iwai: Although unique, its pricing at Costco does not offer a significant advantage over other retailers where better-quality options may be found.

3. Crown Royal: Like Jameson, this Canadian whisky is a common fixture in liquor stores, often offered at comparable prices. Kirkland’s own Canadian blend is a better value alternative.

4. Jack Daniel’s: As a household name, this Tennessee whiskey’s price at Costco is not particularly competitive compared to the multitude of outlets where it can be found at a similar rate.

5. Jim Beam: While it can be a decent choice for cocktails, its price at Costco is comparable to other retailers, diminishing the need to purchase it from Costco specifically.

6. Bulleit: Although solid, Bulleit’s bourbons and ryes can frequently be found at better values from other brands available at Costco.

Methodology

To compile this list, I assessed the whisky offerings at Costco against those at other retailers. My first-hand experience, along with professional and customer reviews, guided my evaluations of both price and quality. The "worst value" labels denote brands that can be easily sourced elsewhere, while "best value" designations highlight those worth seeking out at Costco.

Keep in mind that alcohol availability and prices can fluctuate, so it’s a good idea to check your local store for the most current offerings.
