I have tried this, Lupicia number 8508 from Lupicia France, under the name Belle Journée.
And it´s such an interesting idea, a green tea with rooibos. It was a sample, so worth risking, I was quite unsure if I was going to like it, but indeed it works and it´s oddly refreshing.
I am usually not a fan of grapefruit flavours, and it´s noticeable here, though the peach is more prevalent. I will probably not buy it because of the grapefruit, I might tire of it, but it´s certainly interesting on its own.
Brewed the way Lupicia insists, boiling water 2 minutes, it works (have given up doubting them on how to brew their teas).
