Went with Guayaki’s instructions on this, I think 150 is a little low though. Might try 175 next cup. I’ve had bagged mate before from this brand, but not their loose stuff. Adagio is the only other company I’ve had to compare to.
This wasn’t bad, I enjoyed it. Nice light herb flavor, I think I may steep longer next time. The full ten minutes sounds goods. I like my tea strong. :)
