5 min. wasn't long enough, and 7 might be a little too long. The strawberry was a little bitter after 7 min., but that may have been the white tea biting back. Still can't taste the vanilla oolong, but the smell is definitely there. I may have to play with the percentages.
On the plus side, my boyfriend likes this tea just the way it is. I may keep it this way for him and do a different blend for myself. Maybe just a nice strawberry vanilla oolong without the white tea.
Kinda wish oolong came in more flavors. I occasionally wonder how chocolate oolong would taste.
