Black Insomnia Coffee - Dark Roast Ground - The Strongest Coffee in the World - 1lb (Pack of 6)

Bold flavor, not bitter, good strong coffee.

Nice and strong

This is the most highly caffeinated coffee I’ve ever had. The taste is decent, but it was a little rough on my stomach.

Good coffee as advertised I thought I was going to do from how fast my heart was beating

Flavor was good but couldn’t tell much of a difference between this product and death wish coffee

In doing research for very strong coffee, Black Insomnia came up consistently at the top (or 2nd) for caffeine content. I have a very high tolerance for caffeine, so I'm not easily impressed. This brand, however, comes through for me. I don't feel a sudden jolt or get shaky, but I can feel my energy level surge and sustain for about 6-7 hours. Those who are sensitive to caffeine may need to go slow on drinking this, but I don't see it as a brand that's going to give you heart palpitations, for example. In addition, I have to say I find it rather smooth instead of bitter or biting. Overall, a good buy and good value.

Great coffee

Only way to wake up if your a coffee lover like me, get you a bag of this you won't regret it!
