Perfect Guinness pour requires 5-minute waiting time

Scientists have found that the ideal time to wait between the two-part pour of Guinness is five minutes, significantly longer than the traditional 119.5 seconds recommended by Guinness. This method aims to create a better head on the beer. The two-part pour involves filling two-thirds of the glass, allowing bubbles to settle, and then topping it off. Experts say this technique helps control the nitrogen bubbles, which are crucial for the beer's texture. While Guinness officially supports the two-part pour, some experts question the exact timing. They suggest that the pouring technique affects the beer's quality, but opinions vary on the necessity of the longer wait.
