What roast is used for single origin and espresso drinks?

The choice of Pearl as the correct answer highlights its unique characteristics that make it particularly suitable for both single origin and espresso drinks. Pearl is often a specially curated roast that is designed to enhance the distinct flavors of the coffee beans, allowing the specific origin characteristics to shine through. This is essential for single origin coffees where the focus is on the flavors specific to a particular region, highlighting profiles that can include fruity, floral, or nutty notes.

In espresso preparation, the Pearl roast can provide a balanced acidity and body, which are crucial for achieving a well-rounded espresso shot. The roasting process preserves the complexity of flavors while ensuring proper extraction during brewing, delivering a rich crema and robust flavor profile that espresso enthusiasts appreciate.

Other options do not fit this purpose as well. For example, Old Town and Steel Bridge might be roasts that serve different profiles or blend requirements, and while a medium roast could represent a broad category of coffee, it lacks the specialization and distinct flavor attributes that Pearl provides for single origin and espresso applications. The Pearl roast stands out as the ideal choice for showcasing the specialties of these types of coffee drinks.
