What’s New with THA1 Coffee?
With the goal of enhancing quality, improving market pricing, and deepening processing in Vietnam’s coffee industry, THA1 is a new variety that can meet these demands. Origin
THA1 belongs to the Arabica coffee line and is a selected F5 hybrid variety, a cross between TN1 (which has origins from Ethiopian coffee beans) and Catimor coffee. The THA1 coffee variety has a high level of purity and is propagated through seeds. Characteristics
The THA1 coffee variety has the following features:
Appearance: Compact tree canopy with many branches, suitable for dense planting.
Growth potential: The THA1 coffee can grow well in specific regions such as the Central Highlands, North Central, and Northwest, with the potential to improve average coffee yield up to 3 – 5 tons per hectare (a 10-15% increase per unit area compared to previous coffee varieties).
Ripe fruit has a bright red color, elongated shape, large size, and dense clusters. The seed size is significantly larger than that of Catimor, with a fresh/bean ratio of 5.6; an average weight of 100 seeds reaching 17.3g; and a grade 1 seed achieving 84.9%.
