Giving this another go-around and finishing up the sample packet I have at work. After 3 minutes of steeping I am at least getting a hint of fruitiness, but the flavor is still lacking.
I decided to keep the strainer in and steep this for a ridiculously long amount of time to see if I could coax out some more flavor. 6 minutes in and there are some slight green bean and chocolate notes. At least it does not get astringent.
9 minutes in and this tea actually gets a flavor! The chocolate becomes a stronger and the green beans last into the aftertaste. Still pretty smooth in the mouth and only a teensy bit of astringency.
