Even if the added concentration benefit does turn out to be placebo, this is a great tasting cup of coffee!

Very smooth tasting. Also, it feels great to be able to have a cup of coffee anytime throughout the day and not have to worry about getting jitters. I hope to see this offered in Keurig pods eventually. Still like the grounds for my pour over maker.

Just received my second bag and will definitely be ordering more. I used to think the more caffeine the better (DW /BI), but after my first bag of Serene Cognition I can say that's no longer the case. Great smooth flavor, not nearly as acidic as the others. 14-16 oz in the morning and I'm good to go.

Infused with l-Theanine. Gives me clear and natural energy. I love it!

As a long time Death Wish, and recent convert to Black Insomnia, coffer drinker, thinking caffeine was the answer, I love bio hacker. It's perfect balance of caffeine and taste. Not bitter like death Wish. No crash like black insomnia.
