How does the pourer work on a 1 liter bottle of johnnie walker double black wiskey?

It sounds like you're talking about the stopper on a Johnnie Walker Double Black whiskey bottle, rather than a "pourer." This is a common misconception!

Here's how the stopper works:

* It's a dual-purpose stopper/pourer: The top part of the stopper acts as a cap to seal the bottle, while the bottom part has a spout designed for pouring.

* The pourer is built into the stopper: There's no separate "pourer" piece. The spout is integrated into the stopper itself.

* It features a built-in pourer: The spout is designed to control the flow of whiskey and prevent spills. It usually has a narrow opening that allows for a controlled pour.

Let me know if you have any other questions about whiskey or its packaging! 🥃
