Step-by-step explanation:
To answer your question, Dutch Bros Private Reserve espresso doesn't have a standardized caffeine content provided by the company for a double shot. However, generally, a single shot of espresso contains about 63-73 mg of caffeine. Therefore, a double shot would contain approximately 126-146 mg. Since this is a specific inquiry about Dutch Bros's proprietary blend, it would be best to consult the company's nutritional information for exact figures or to consider the average amounts specified for espresso. It's important to note that caffeine content can vary based on the coffee's blend, roasting, and brewing technique.
