How do you pour a stout to achieve the perfect creamy head and cascading effect?

To pour a stout for the perfect creamy head and cascading effect, tilt the glass at a 45-degree angle and pour the beer slowly down the side of the glass. As the glass fills up, gradually straighten it to create a thick, creamy head. This technique helps release the nitrogen bubbles in the beer, resulting in a cascading effect and a smooth, creamy texture.
