Pros & Cons

Pros

Rainforest Alliance Certified and Kosher — unusual for a bulk private-label coffee at this price point
Bold, smoky, heavy-bodied — a genuine French roast character, not a watered-down “dark-ish” blend
Strong bulk value at Costco — roughly $7.50–$9/lb, well below most specialty roasters
100% Arabica; historically custom-roasted by Starbucks under contract, which built its early reputation

Cons

Independent taste tests have ranked it at or near the bottom of Kirkland’s own coffee lineup, describing it as over-roasted and bitter
Visibly oily beans — a sign of aggressive roasting that reads as harsh to drinkers used to milder coffee
Not single-origin; sourcing detail beyond “Central & South America” isn’t disclosed
Current roaster is unconfirmed — Starbucks’ roaster credit disappeared from the bag around late 2023/early 2024

About the Brand

Kirkland Signature is Costco’s private-label brand, launched in 1995 — it isn’t a standalone coffee roaster but a store brand manufactured under contract. For years the whole bean lineup was custom-roasted by Starbucks, though that roaster credit quietly disappeared from Kirkland bags around late 2023/early 2024, and Costco hasn’t publicly confirmed a replacement; likely candidates include contract roasters such as Rogers Family Company. The main draw is Costco’s bulk pricing and quality-control reputation rather than any specialty-roaster identity of its own.
