I find unusual spirits interesting, and I want to hear about the ones you have.
Is this what you are talking about?

Seems interesting
If you find it, please let me know. I looked around and struck out. It sounds so odd, is like to try it. Perhaps bring it camping to compare its flavor to a forest’s!
