Overview
Bulk Oolong Tea is a traditional Chinese tea known for its complex flavor profile, ranging from floral to woody notes depending on oxidation levels (10-70%). It occupies a middle ground between green and black teas, offering versatility for both hot and cold brewing. Primarily produced in Fujian, Guangdong, and Taiwan, bulk packaging caters to commercial buyers like restaurants, tea houses, and retailers. The leaves are typically rolled into tight pellets or strands to preserve freshness during storage and transport.
Product Features
High-grade bulk Oolong exhibits intact, uniformly sized leaves with a glossy appearance. The aroma should be clean and persistent, without mustiness. Key varieties include Tieguanyin (floral), Da Hong Pao (roasty), and Dong Ding (creamy). Oxidation level dramatically affects flavor: lighter Oolongs (10-30%) offer grassy freshness, while heavily oxidized versions (50-70%) develop caramel-like richness. Some premium batches undergo charcoal roasting for added depth.
Main Uses
Beyond traditional brewing, bulk Oolong serves as a base for milk teas, cocktails, and desserts due to its robust flavor. Its polyphenol content makes it popular in health-focused markets, with studies suggesting metabolic benefits. In B2B contexts, large packs (5-25kg) reduce per-unit costs for high-volume users. Some manufacturers use Oolong extracts in cosmetics for their antioxidant properties.
Culture and Development
Oolong tea processing was refined during China's Ming Dynasty, with traditional techniques like 'shaking' leaves to bruise edges for partial oxidation. The name 'Oolong' (Black Dragon) possibly references the dark, twisted shape of processed leaves. Modern bulk packaging emerged in the 1980s to meet export demand. Today, nitrogen-flushed aluminum foil bags are industry standard, extending shelf life to 2-3 years without refrigeration.
B2B Procurement Guide
When sourcing bulk Oolong, verify certifications like organic or ISO 22000 for food safety. Minimum order quantities (MOQs) typically start at 10kg. Key metrics include: moisture content (<6.5%), purity (no stems), and pesticide residue reports. Negotiate based on seasonal availability – spring harvests (April-May) command premium prices. For consistency, request samples from the same batch. Sea freight is cost-effective but requires moisture-proof containers.
