My experience with Fire is exactly the same. The cigar tasted charred, like an overly done burger. I wasn't too pleased with it. The Corojo is a different story, and with age, it turns into a sweet, earthy smoke with a little meat on the bone.
In my opinion, IT's top maduro is the Super Fuerte, an excellent cigar that can be had at some great prices these days. It pairs wonderfully with a strong cup of coffee or double espresso.
