See recurring flavor notes and style preferences from the pours you already love.

Every bottle gets a story, not just a score.

Ratings are useful. Memory is better. Whiskey Thief is designed for the bottle you opened with friends, the single barrel you keep comparing against, and the dram that taught you a new note.

As your journal grows, Whiskey Thief helps you notice the through-lines: orchard fruit over smoke, rye spice over dessert, coastal brine over heavy oak. Your taste becomes easier to name.

Built by a collector, for collectors.

Whiskey Thief started with a simple frustration: forgetting what a bottle tasted like, and losing track of a shelf that kept quietly growing. I wanted a journal that remembered for me — and got smart enough to show me my own palate. That is what I set out to build at Cast Shadow, and it is the app I reach for every time I open something worth remembering.
