Our Verdict
Peak State stands out with its unique infusion process that embeds mushroom extracts into coffee beans during roasting, resulting in a cleaner cup than most competitors. Full ingredient transparency with 100mg of each of 5 species is commendable, though the 500mg total mushroom dose is on the lower end of the category. B-Corp certification and strong sustainability credentials add trust.
