Chicory is used on its own and in mixtures with coffee, including products associated with New Orleans and Louisiana. A bag described as chicory coffee therefore needs a closer reading: it may contain roasted chicory alone, regular coffee with chicory, or a mixture using decaffeinated coffee. Those are different products, even when the names look similar.
The source suggests beginning with a modest chicory proportion when making a blend at home. A measured trial is more informative than replacing a large amount of coffee without recording it. Compare the flavor and body with your usual brew, then adjust the mixture gradually. Chicory and coffee do not behave identically during extraction, so the blend may also require changes to the brewing routine.
Pure chicory does not supply the caffeine found in coffee beans, but a blend containing regular coffee still does. Decaffeinated coffee is not necessarily caffeine-free either, and a universal milligram figure cannot be assigned to an unspecified homemade mixture. Read the actual ingredients and the seller's information. Choose chicory for its distinctive contribution to the cup rather than relying on generalized health or acidity claims.
