I used to work at a starbucks and it was one of the two teas...along with blecky awake...that folks would throw a hissy about if we ran out. I was so pissed one day I had a cup of it to see what it tasted like to see if we could some how mimic the taste. the result? green tea with a TEEENY TINY DROP of strawberry flavor tasted indistinguishable from lotus. Actually, when we used the china green tips and strawberry it tasted better.
i don't think it actually has a strawberry flavor to it but hell...it tasted pretty damn similar. I know lots of coffee and specialty gormet stores sell strawberry syrups [torani is a good brand to get] so that would be my recomendation...plus then you can use a GOOD quality green tea.
I admit though...i do love that stupid ole tazo lotus too nowadays
