Why is it important to use a fully extracted double shot as soon as possible?

Using a fully extracted double shot promptly is crucial because it helps maintain the optimal flavor profile of the coffee. Freshly brewed espresso has specific flavors and aromas that are best experienced immediately after extraction. Over time, these compounds can change, leading to a loss of freshness and a potential increase in bitterness. When espresso sits too long, the natural oils and compounds continue to interact with oxygen, causing undesirable flavors to develop.

Additionally, the temperature of the shot plays a significant role in how flavors are perceived. Once a shot cools down too much, it can alter the taste experience, making it less enjoyable for the customer. While serving a shot hot and ensuring customer satisfaction are important, the primary reason to serve it quickly is to preserve its intended taste.
