These conditions allow coffee beans to develop slowly, accumulating rich flavors and achieving exceptional quality.

By understanding and appreciating these intricate processes and conditions, we can truly savor the remarkable journey from coffee plant to cup, where nature and humanity perform a beautiful waltz.

 

Seeding and planting process

 

According to the Western Highlands Agriculture and Forestry Science Institute, coffee seeds should be nurtured in a nursery for 6-12 months before being planted in the field. The recommended planting density for Robusta coffee is 1,100-1,300 plants per hectare, with row spacing of 2.5-3 meters and plant spacing of 1-1.2 meters.

Efficient watering practices

Proper irrigation is crucial for the healthy growth, even flowering, and high yield of coffee plants. The Food and Agriculture Organization (FAO) recommends an average water requirement of 1,500-2,000 liters per plant per year. Using drip irrigation or sprinkler systems can save 40-50% of water compared to traditional methods.

Nutritional needs

Fertilizing coffee plants should be based on their nutritional needs at different growth stages and soil analysis results. The Vietnam Academy of Agricultural Sciences suggests an average fertilizer dosage for a hectare of mature coffee trees to be 250-300 kg of nitrogen (N), 100-150 kg of phosphorus (P2O5), and 200-300 kg of potassium (K2O). Regular organic fertilization 2-3 times a year improves soil quality and provides sustainable nutrients.

Pruning and canopy management

Pruning is essential for maintaining a balanced, well-ventilated canopy, concentrating nutrients for the fruit. The Ministry of Agriculture and Rural Development recommends pruning 2-3 times a year to remove old, overgrown, and diseased branches, keeping an optimal number of 25-35 fruit-bearing branches per tree.

Pest and disease control

Pests and diseases significantly affect coffee yield and quality. Common threats include stem borers, leaf aphids, and rust disease. Regular field inspections, early detection, and the application of integrated pest management (IPM) strategies are crucial for effective pest control.

Understanding and implementing these meticulous techniques ensure that each coffee plant is nurtured to its full potential, resulting in beans that deliver a superior coffee experience, reflecting the dedication and harmony between nature and human effort

However, this method is labor-intensive and time-consuming, with harvesting costs accounting for 30-40% of total production expenses.

Mechanical harvesting and its conditions

In contrast, mechanical harvesting can increase labor productivity by 10-15 times compared to hand-picking. However, the Central Highlands Research Center for Industrial and Fruit Crops warns that improper use of machinery can lead to fruit dropping, bruising, contamination, and damage to the trees. Therefore, it is essential to develop mechanized harvesting processes suited to specific coffee varieties, field conditions, and management practices.

Coffe cultivation and harvesting: A dance of nature and humanityFor Specialty Coffee, hand harvesting is mandatory. Harvesters selectively pick only the ripest cherries, ensuring uniform ripeness and minimizing the presence of unripe or damaged fruit. Although this process requires more time and effort, it results in superior coffee quality.

 

Impact of timing and harvesting methods on coffee quality

 

Ripening stage and coffee quality

Research by the Institute of Vegetable and Fruit Research indicates that coffee cherries achieve their best quality when harvested at full red ripeness. At this stage, the beans have optimal levels of sugar, caffeine, fat, and aromatic compounds. Harvesting green cherries results in lower sugar and fat content, while overripe cherries are prone to fermentation and spoilage. The International Coffee Organization (ICO) recommends harvesting coffee in multiple rounds, approximately 3-4 times per season, to ensure uniform ripeness.

Importance of harvesting time of day

The time of day when coffee is harvested also affects its quality. Studies by the Center for Research and Technology Transfer show that coffee picked in the morning, after the dew has dried, has a higher germination rate and less spoilage compared to coffee harvested in the afternoon.
