Raised bed drying

Raised beds, or African beds, dry coffee on mesh tables with airflow on all sides: slower, cleaner, more stable, and now the standard for specialty lots.

Raised beds — African beds — are mesh tables about a meter (3 ft) off the ground on which coffee is dried in a thin layer.

Why they are better

Airflow from all sides, so coffee dries evenly rather than from the top down.

No ground contact, removing a contamination route.

Slower and cooler drying, which is consistently associated with better cup quality and better stability in storage.

Where they came from

East Africa, and the name reflects it. They are now standard for specialty lots across every producing region.

The cost

They occupy far more area per metric ton than a patio, they need building and maintaining, and they are labor-intensive to load and turn.

For a smallholder co-operative, investment in raised beds is often the single highest-return quality intervention available — larger than variety changes.

Naturals especially

Natural processing depends on even drying more than any other method. The rise of good Ethiopian and Guji naturals tracks the arrival of raised beds almost exactly.

Brewing it

Nothing specific — it shows as cleanliness and consistency, and in coffee that holds its flavor longer after harvest.

What you need to make it

The equipment this actually requires — not a shopping list, the shortest route to doing it properly.
