This is one of those teas I despised at first. I decided to try it out once. Hated it. The sencha mixed with the berries was one of the most awful things I had tasted. I tried sweetening it, and nothing. It was worse.
Fast forward a few months, I re-smell it, and begin making a cup for myself. My love for green tea skyrocketted, and I decided to give a shokai-based green a shot. I found that 1:30 gives your the best flavor: the goji taste is there, and the sencha taste is there without being overbearing. This one you really need to be careful for. No more than 2 minutes!
