Blend (coffee blend)

Mix of coffees from two or more origins, roasted separately then blended, or roasted together. Goal: taste consistency (commercial espresso blend), complexity (specialty blend), or sugar/acidity/body balance. House blends are often roasters' secret recipes.

Background & Context

A coffee blend is a mixture of two or more single-origin coffees, combined before or after roasting to achieve a flavour profile that is more consistent, complex, or commercially appealing than any single origin alone. Blending has been the backbone of the commercial coffee industry for over a century — Lavazza, Illy, and Segafredo built their global businesses on proprietary blends that deliver consistent flavour year-round regardless of harvest variability. In the specialty world, blending has a more nuanced reputation. 'Seasonal blends' that change when component origins' harvests rotate are celebrated; 'espresso blends' combining, say, a Brazilian natural (body, chocolate) with an Ethiopian washed (brightness, florals) are considered craft. The most common espresso blend structure in specialty is a base of 60–70% Brazilian Arabica (for body, low acidity, nutty notes) combined with 30–40% of a high-acidity origin (Ethiopian, Kenyan, Colombian). Pre-roast blending (roasting components together) allows for simpler logistics; post-roast blending allows each component to be roasted to its optimal profile. In competitive barista programmes, single-origin espresso has displaced blends as the professional benchmark.

Practical Use

When evaluating a blend for purchase, look for roasters who disclose the component origins — this transparency signals quality control. Avoid blends with no origin information, which often indicates low-cost commodity components. For home espresso: blends are generally more forgiving than single origins because their lower acidity and more balanced profile tolerate minor extraction variance. For filter brewing, single origins typically offer more interesting complexity.
