The leaf smells very green and strongly of authentic vanilla. It’s the smell I get when I cook with vanilla beans.
I steeped it as directed, 4 minutes at boiling. As soon as the water hit the sachet the air was infused with the vanilla smell. I steeped it sitting right in front of me so I could enjoy the fragrance for the full steeping time.
The tea was still really hot after four minutes, so I let it sit for a few minutes while I played Operation with the sachet. The leaves had totally filled it during the steep and I could almost hear them yelling, “Let me out!” So I did.
