I purchased both The Signature Blend and Columbia. I read the reviews about both before purchase. Afterward, I decided to opt for two boxes of The Signature Blend and one of The Columbia Blend. I should have stuck with my first choice. I like both but The Columbia Blend is my first choice. I hope anyone who reads this learns that you can't always believe in house or signature blends over others.
I purchased the Signature and Columbia blends after reading other reviews. I somewhat like the Signature Blend. It does have a certain richness to it. I found if you shorten the cup size as in 8 oz. not 10 oz. it tastes better. It is a nice change from real dark roasts.
