Three grades. Every market.
Uganda is one of the world's leading Robusta origins. We supply beans graded by screen size for uniform roasting and quality.
01 Grading
How screen sizing works.
After milling, beans are graded by screen size - each screen number is the hole size in sixty-fourths of an inch. A bean that stays on a Screen 18 sieve is at least 18/64″ (about 7.1 mm) across.
A larger screen number means larger, more uniform beans, better prices, and more consistent roasting. Every Karaz lot is screen-graded, hand-checked for defects, and documented before export.

SC 18 Premium Export
The flagship.
The largest beans at around 7.1mm - the most uniform and sought after, ideal for buyers who want clean, high quality lots. SC 18 commands the strongest prices and roasts with exceptional evenness.

SC 15 Commercial Standard
The workhorse.
Medium to large beans at around 6.0mm - dependable and well balanced, with broad demand and good value. SC 15 is the backbone of commercial roasting: consistent enough for quality blends, priced for volume programmes.
