From Coffee Cherry to Bean

The Anatomy of a Coffee Cherry

What we call a "coffee bean" is actually the seed of a fruit — the coffee cherry. Understanding its structure reveals why processing matters so much:

• Outer skin (exocarp) — turns red, yellow, or orange when ripe
• Mucilage (mesocarp) — sweet, sticky fruit flesh
• Parchment (endocarp) — a protective papery layer
• Silver skin (spermoderm) — a thin membrane around the seed
• The seed — what becomes the green coffee bean

Most cherries contain two seeds facing each other (flat beans). Occasionally, only one seed develops, creating a rounder peaberry — prized by many for its concentrated flavor.

Harvesting Methods

Selective Hand-Picking

Workers pick only ripe cherries by hand, often returning multiple times during harvest season. This is labor-intensive but yields the highest quality — the standard for specialty coffee, including what we source at Röstschmiede.

Strip Picking

All cherries are stripped from the branch at once, regardless of ripeness. Faster and cheaper, but the mix of ripe and unripe fruit can compromise quality.

Mechanical Harvesting

Machines shake trees to dislodge cherries. Efficient for large flat plantations (common in Brazil) but less selective.

From Cherry to Green Bean

After harvesting, cherries must be processed quickly to prevent spoilage. The processing method — natural, washed, or honey — determines how much fruit flavor transfers to the bean. The resulting green beans are then dried to around 10-12% moisture, hulled, sorted, and graded before export.

Quality Begins at the Source

The condition of the cherry at harvest is the single most important factor in cup quality. No amount of roasting expertise can compensate for unripe or defective cherries. That is why traceability and direct relationships with farmers are at the heart of specialty coffee sourcing.
