As far as flavored coffees go, top notch!
My wife is pregnant and is trying to avoid caffeine (a mighty endeavor for her). I ordered this coffee for her in decaf, primarily as an evening treat. I've not been a huge flavored coffee fan, but I have to admit - it's me who's frequently saying, "so...want any of that great 8th Sin decaf? I'll make some for both of us!"
The flavors in Sinful Delight are well balanced and not overbearing. Very complimentary. It's rich and smooth - I recommend brewing it quite strong and using a spot of cream. I appreciate the fact that one can still taste the high quality coffee on which it's made instead of just gulping an artificial flavor bomb that covers up cheap beans. I might even go so far as to say "decadent!" Well worth a try...even for coffee snobs like me.
