Thank you very much for your responses. Now I know! Hallelujah! \
Made my Lovely Pair of Coconuts with Koloa over the lower ABV options I had and everybody loved it.

Can anyone tell me the difference between coconut rum, coconut cream liqueur, and coconut liqueur? Is it just the alcohol level or what. I'm losing my mind.

Hi, everyone, first off thanks for your responses and suggestions. Update: on my last trip to Total Wine, I saw Izarra Verte and Izarra Jaune available. They were highly recommended as substitutes for the Chartreuse's. I haven't cracked them yet, but we'll see!

Thank you, Paul. I will try your suggestions. I have Strega but it looks like I might have trouble finding the Grandmont in my area.
