Processing
Semi-washed covers methods between washed and natural: skin removed, some mucilage stripped, little fermentation. Why the term means little on a bag.
Semi-washed covers a group of methods that sit between fully washed and natural, and the term is used loosely across producing countries.
The skin is removed mechanically. Some of the mucilage is stripped off — often by a mechanical demucilager rather than by fermentation — and the rest dries with the bean.
There is little or no tank fermentation, which is the main departure from washed processing.
Water. Full washing traditionally uses a great deal of it, and semi-washed dramatically reduces that.
Time. No overnight fermentation means faster throughput.
Consistency. Mechanical demucilaging is more controllable than waiting for enzymes.
Between the two poles: cleaner and brighter than a natural, sweeter and fuller than a washed. Less complex than either done exceptionally well.
Semi-washed, pulped natural, honey and giling basah all overlap and are used inconsistently by region. Indonesian wet-hulling is sometimes labeled semi-washed and is a genuinely different process.
If a bag says semi-washed, the roaster’s description of what actually happened matters more than the label.
Versatile at medium roast. Filter and espresso both work.
The equipment this actually requires — not a shopping list, the shortest route to doing it properly.
60° cone · spiral ribs · 1–4 cups
The most transparent cup you can brew for twenty dollars, and the least forgiving. 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 the clearest grind you can buy at this price.
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.
