Which bottles should a home bar stock first? A planner that counts the cocktails each one unlocks

The best first bottle for a home bar isn't the cheapest or the fanciest. It's the one that shares ingredients with the most drinks you already want to make.

Tap what's on your shelf in the planner and it shows which of 19 classic drinks (two of them alcohol-free) you can make now, which are one ingredient away, and which purchase would open the most new ones. Start with fresh citrus, syrup and soda, then add one spirit at a time.
