Overview

Organic lion's mane and chaga are the added ingredients in this dark roast coffee from Honduras. The brand sells it as a focus coffee, and the listing labels it certified organic, low acid and single origin.

Added mushrooms, a stated caffeine amount and organic, low acid, single origin labels give it a clear profile for buyers who want more than plain coffee. The listing contradicts itself on form, calling it ground in the title and instant in the coffee type field, and the serving size is not stated.

Who it's for

A coffee drinker curious about mushroom blends, who also wants organic, vegan and gluten free labels, will find them together here. Shoppers who want plain beans, or who need the serving size and brew ratio, should read the package first.

Pros and cons

Pros
  • USDA organic, vegan, gluten free
  • Single origin Honduran coffee
  • Low acid label
  • Caffeine amount stated per serving
Cons
  • Form shown as ground and instant
  • Serving size not listed
  • Mushroom taste not described

Performance notes

The caffeine figure is given per serving, so the strength of a cup depends on how much coffee makes a serving, which the listing does not state. Dark roast points to a bolder, smoky flavor, and a low acid label suggests a smoother cup. Mushroom additions can change flavor and body slightly, so taste may differ from plain coffee.
