How to Use
Use about 1 tablespoon of grounds per 6 fl oz of water in a standard drip coffee maker; it also works in pour-over brewers at roughly a 1:15 coffee-to-water ratio and in Moka pots filled to the basket line. It is not recommended for French press or cold brew, which need a coarser grind. Store the tin in a cool, dry place away from direct sunlight with the lid tightly sealed, avoid the refrigerator or freezer, and use within 2 to 4 weeks of opening for the best flavor.

Frequently Asked Questions
Is Kirkland Signature Decaffeinated Coffee really caffeine-free?
It is 99.7 percent caffeine free, exceeding the FDA standard of at least 97 percent caffeine removal for coffee labeled decaffeinated. A typical 8 fl oz cup of regular coffee has about 80 to 100 mg of caffeine, while the same cup of this decaf has only a few milligrams, negligible for most caffeine-sensitive drinkers.
What does the water-process decaffeination method mean?
Water process decaffeination removes caffeine from the green beans using only water and activated charcoal filtration, with no chemical solvents involved. The beans soak in hot water to draw out caffeine, the water is filtered to remove it, and the beans reabsorb their remaining flavor compounds before roasting.
How should I store Kirkland Signature Decaf Coffee once opened?
Keep the tin in a cool, dry place with the lid tightly resealed after each use, away from direct sunlight. Do not refrigerate or freeze the opened coffee, since temperature changes speed up flavor loss. Use it within 2 to 4 weeks of opening and check the best-by date on the tin.
What is the difference between Kirkland Signature Decaf and Kirkland Signature Colombian Coffee?
Decaf Coffee uses select beans from the Americas, water-processed to remove about 99.7 percent of the caffeine, while Colombian Coffee is made from fully caffeinated Supremo-grade beans grown in Colombia. Both are dark roasted, fine ground, and sold in the same 3 lb tin.
