Ok, so I tried upping the tea amount and reducing the steep time, and it worked like a charm!
With 2 tsp. / 8 oz. water, I yielded 4 strong cups before the tea started to really weaken. It was great!
Also, on the second and third cup, the buttery flavor really started to come out with the sweetness, and I tasted a good amount of nuttiness in later steepings as well.
Again, this is the best TGY I’ve ever had!
