Fee Brothers Zwarte Walnootbitters

The bottle lasts forever since a little goes a long way, and that toasted nuttiness really rounds out a whiskey sour without any alcohol burn. I've been experimenting with it in plain soda water too, and it adds a surprisingly cozy depth.

A few drops of this in an Old Fashioned really brought out a rich, toasted nuttiness I wasn't getting before. It's surprisingly versatile for something so specific.

A bottle of this in the bar cart instantly upgrades any rye whiskey, the nutty depth cutting through the sweetness without making things taste like dessert. It’s alcohol-free, so I can even splash a few dashes into a ginger ale for a rich, savory soda that feels far more complex than it should.
