A dark, Demerara style rum from Guyana, Lemon Hart 151 is one of canonical Tiki drink ingredients, used in drinks like the Zombie. I’ve not been able to find any details beyond this, but if you’re running low, now might be a good time to stock up.
I do recall that the Peace Arch US/Canada border crossing had Lemon Hart, so if you’re coming back into the US from Canada soon, there may be opportunities there.
I’ll update this as I learn more. [[Well, four years later, this didn’t happen. 🙂 ]]
