What is meant by a "coffee blend"?

A "coffee blend" refers to the practice of combining different coffee beans, often from various origins or roasteries, to achieve a specific and desired flavor profile. This technique allows roasters to enhance the complexity, balance, and overall taste of the coffee, appealing to a wider range of palates. By blending beans with complementary characteristics, such as acidity, sweetness, body, and flavor notes, a barista or roaster can craft a unique and consistent product that might be difficult to achieve with single-origin coffees alone, which typically exhibit the distinct flavors of their geographical source.

The other choices do not accurately define a coffee blend. A single origin coffee refers to beans sourced from one location, which emphasizes the unique characteristics of that locality. A brewing method describes how coffee is prepared, like espresso or pour-over, rather than referring to the composition of the coffee itself. A cold brew is specifically about a brewing process that uses cold water, not about blending different beans. Thus, the concept of a coffee blend is distinct and centered around flavor creation through the combination of different beans.
