I have taken a liking to Starbuck's Iced Passion Tea (with or without lemonade). Since I'm just a poor business owner, I thought I would buy a box of their Tazo Passion Tea and try to make some myself. Unfortunately, every time I steeped the tea, it ended up being too bitter.
After several attempts, I had the thought that it was my brewing technique that was causing the bitter taste. I had originally been pouring the boiling water on to the tea bag in an attempt to extract maximum flavour. Unfortunately, this seems to also extract maximum bitterness. When I made a cup of tea and deliberately avoided pouring the water onto the tea bag, the tea came out fine.
I'm looking forward to finding a good sugar/syrup/lemonade combination next.
