Variety · Kenya
Ruiru 11 is a compact Kenyan coffee variety released in 1985 to resist berry disease and leaf rust: clean, milder than SL28, and now often planted with it.
Ruiru 11 was released by Kenya’s Coffee Research Station in 1985, bred for resistance to coffee berry disease and leaf rust — both of which were devastating Kenyan farms planted with SL28 and SL34.
Resistance to the two diseases that threatened the industry.
High yield and a compact habit allowing dense planting.
Together those transformed the economics for smallholders who could not afford the fungicide programs that SL varieties require.
Cleaner and milder than SL28. It lacks the blackcurrant intensity that made Kenyan coffee famous, and it is a perfectly good coffee — sweet, balanced, moderate acidity.
That gap is real and it is smaller than purists claim. Growing conditions and processing still dominate.
Kenya has spent forty years balancing survival against reputation. Farms that keep SL28 and SL34 accept disease risk and fungicide cost for a premium cup; farms with Ruiru 11 get a reliable crop.
Most now plant a mixture.
The 2010 successor: also resistant, taller, and generally regarded as cupping closer to the SL varieties. It is gradually displacing Ruiru 11 on quality-focused farms.
Filter, light to medium roast.
The equipment this actually requires — not a shopping list, the shortest route to doing it properly.
60° cone · spiral ribs · 1–4 cups
A transparent cup, and an unforgiving one to brew. Ceramic holds heat where plastic does not — and the open bottom means your pour, not the dripper, decides the coffee.
Best for: Someone who wants to taste what a single-origin coffee is actually doing.
64 mm (2.52 in) flat burr · filter only · single dose
64 mm (2.52 in) flat burrs, near-zero retention and a footprint the size of a mug, built for filter and honest about not doing espresso. For pour-over it is built for a clear, even grind.
Best for: V60, Chemex, AeroPress and batch brewing, where clarity is the whole point.
0.9 L · ±1 °C (±1.8 °F) hold · counterbalanced gooseneck
The best-pouring kettle sold, and the hold function matters more than the thermometer. Expensive for boiling water — but if you brew pour-over daily, it is the accessory that most improves the cup.
Best for: Daily pour-over, where flow rate is the variable you are trying to control.
