Haha! That's definitely the danger of the infinity bottles! I've been drinking mostly rum lately, and an infinity rum bottle sounds like something I need to try.
I'm loving the tincture. I used Darcy O'Neil's recipe and it is a banger. Super simple and really spicy. I only need like 1.5ml to 6oz of soda water to make a refreshing sipper. I would love to make a ginger beer, but I just don't have room right now.
