Kenya AA vs AB Coffee: What Roasters Need to Know

Kenyan coffee is known for its strict grading system, which helps classify coffee beans based on size and density.

For roasters sourcing Kenyan green coffee beans, understanding the difference between AA and AB grades is important.

What Does Kenya AA Mean?

Kenya AA refers to the largest bean size in Kenya's grading system.

These beans are sorted using large screen sizes and are often associated with premium coffee lots.

Kenya AA coffees frequently produce vibrant cups with berry, citrus, and wine-like flavor notes.

What Does Kenya AB Mean?

Kenya AB beans are slightly smaller but represent a large share of Kenya's coffee production.

Many exceptional coffees are graded AB and still deliver outstanding flavor profiles.

In fact, many roasters prefer AB coffees because they often provide excellent quality at slightly lower prices.

Does Bean Size Affect Flavor?

Bean size alone does not determine cup quality.

While larger beans may roast more evenly, factors like:

• farm elevation
• processing method
• varietal
• drying practices

have a greater impact on the final cup profile.

How Roasters Choose Between AA and AB

Many roasters purchase both grades depending on their roasting goals.

AA lots are often used for premium single-origin offerings, while AB lots may be used for blends or seasonal releases.
