Description
Coffea arabica ‘Catuaí’ is a compact and highly productive Arabica coffee cultivar developed in Brazil through a cross between ‘Mundo Novo’ and ‘Caturra’. It is widely grown in coffee-producing regions for its reliable yields, manageable size, and good cup quality. The plant forms a dense, evergreen shrub typically reaching 2 to 3 meters in height, with short internodes and sturdy branches that help support heavy fruit production.
The glossy, dark green leaves are complemented by clusters of small, fragrant white flowers that develop into coffee cherries. Depending on the selection, fruits may ripen to red or yellow, each containing the characteristic coffee seeds. The flavor profile is generally smooth and balanced, with mild acidity and pleasant sweetness, making it suitable for a wide range of coffee styles.
Catuaí performs best in warm, humid, tropical to subtropical climates, particularly at moderate elevations. It prefers partial shade, fertile, well-drained soil, and consistent moisture. Its compact growth habit allows for higher planting density and easier maintenance compared to taller varieties.

Coffea arabica 'Catuai' is a hybrid variety created by crossing Mundo Novo and Caturra, officially released in Brazil in 1972 and now extensively cultivated across Central and South America. Germination is slow and demands consistent environmental conditions, taking 30-60 days depending on temperature and seed age, with fresh seeds germinating faster than stored seeds. This vigorous yet compact cultivar is valued for high yield potential and good cup quality, making it one of the world's most commercially important coffee varieties.

Soaking — 24 hours
Pre-soak seeds in water for 24 hours before sowing. Remove papery outer layer (silver skin) before imbibition to reduce rotting risk.

Additional notes
Treat seeds with fungicide (e.g., Vitavax 40 WP at 1g/kg) to prevent fungal contamination. Remove all fruit pulp and mucilage; dry in shade for 12 days. Maintain seed moisture content between 10-35% to preserve viability.
Substrate & Container
Recommended substrate
Well-draining sandy loam with organic matter, or mixture of vermiculite, perlite, and peat moss (1:1:1). Slightly acidic soil (pH 5.5-6.5) preferred.
Recommended container
Seed flats, seedbed boxes (20cm depth), or individual plastic bags
Growing Tips
Keep seeds moist but not waterlogged—use misting or keep a moist paper towel over seeds to prevent drying out. Use plastic/polythene tunnels to retain heat and accelerate germination in cooler months. Radicle emergence appears at 3-4 weeks; complete germination with expanded cotyledon leaves occurs at 4-6 weeks. Plant seeds in parchment (pergamino) skin when available for better protection. Newly harvested seeds germinate faster (2.5 months) than stored seeds (6 months). Maintain humidity above 90% and keep seeds in darkness during germination. Transfer seedlings to secondary nursery beds once cotyledonary leaves appear.
