1. Robusta's "industrial revolution gene"
Core advantages
Strong resistance: can be grown in low altitude/high temperature areas (29 million bags per year in the Mekong Delta of Vietnam).
High oil content: gives espresso a rich Crema (twice the thickness of Arabica).
Cost efficiency: unit output is 30% higher than Arabica, and the price is 40-60% lower.
Flavor characteristics
Advantages: mellow bitterness (suitable for milk drinks), woody tones (spices of Malabar in the Indian monsoon).
Disadvantages: prone to rubber/burnt flavors (due to insufficient drying in rainy areas).
2. Application scenario analysis
Espresso: 10-30% Robusta blend, enhanced body and lasting foam (such as Illy Classico).
Instant coffee: accounts for 95% of the world's instant raw materials (freeze-drying technology retains high caffeine characteristics).
Innovative uses: base for Vietnamese egg coffee and Philippine Kopiko candy.
