Ninh Binh Pineapples (Cayenne and Queen varieties) are prioritized by international importers for their superior flavor and nutritional value. The Queen variety is noted for its exceptionally high sweetness (16.70 - 17.87 Bx), while the Cayenne variety offers a rich, juicy flavor and large mass (1.53 - 1.78 kg). Both varieties are fiber-free and possess a significant Vitamin C content. This unique quality is the result of a perfect synergy between specialized natural conditions and local expertise: 1. Ideal Temperature Regime: High annual cumulative temperature (8,800 oC). Critically, the wide day-night temperature variation (4-6 oC) during the flowering stage maximizes the accumulation of sugars and flavor compounds, creating the distinct taste profile. 2. Balanced Climate & Hydrology: High average annual rainfall (approx 2,078 mm), evenly distributed, supplies ample water. The lower temperatures from December to February are also essential for specific developmental stages of the plant. 3. Unique Soil Composition: The semi-mountainous terrain provides excellent drainage. The soil, primarily red-brown/red-yellow earth with high clay content, is crucial for efficient water and nutrient retention, satisfying the pineapple’s need for moisture. The favorable level of trace elements in the soil also enhances flavor. 4. Cultivation Expertise: Decades of accumulated experience in selection, fertilization, irrigation, and harvesting at the correct physiological stage are the final factors that guarantee export-grade quality. If you are seeking a reliable, high-quality source for Cayenne and Queen Pineapples, Ninh Binh is a premier and highly dependable region.
