Great coffee
Love this coffee. Now I buy no other coffee. This dark roast is good for those used to dark roast coffee. If you try the medium roast from being dark roast you’ll find it a bit weak and need to adjust. I still slightly adjust since I like my coffee very strong. It’s worth the price and yes it does boost your energy. Since I drink it both black and with creamer it still tastes good and is not as acidic as coffee. I keep ground coffee in a tightly sealed container.

Best Cup of Coffee I Can Remember
I’ve had a bag sitting in my kitchen for probably a couple of months due to my not wanting to figure out how to use my new coffee maker. Geez Louise it was simple. I made myself a hot cup of the Four Sigmatic with Lion’s Mane and it was absolutely delicious! There was zero bitterness that I’m used to with lots of coffees. The taste was very smooth and delightful!

Helps me stay healthy
I first learned about Lion's Mane when a family member was ill. I drink a cup each morning and it seems to help me deal with daily tasks more clearly. No stomach issues and the amount of caffeine does not make me jittery. Excellent smooth blend and taste. Great way to start the day!

Good coffee, way to expensive
Great tasting coffee. Smooth, strong without the gitters. Only issue is, I will only buy it on sale. Way, way to expensive for a regular coffee drinker that likes a strong cup of Jo.

Focusing Better
I am focusing better. I'm 10 month post 3rd concussion. I also get fog brain from diabetes sugars going high occasionally. This Think coffee is helping me to focus better. Love it and it tastes great! No mushroom taste.
