White tea processing

White tea processing is the most minimally-interventionist of the six Chinese tea categories. Where green tea uses immediate kill-green to halt oxidation, oolong uses controlled partial oxidation, and black tea uses full oxidation, white tea simply lets nature take its course: hand-picked downy buds (and young leaves for some grades) are placed on bamboo trays in well-ventilated indoor spaces and allowed to wither naturally for 24–72 hours. During withering, the leaves slowly lose moisture and undergo light natural oxidation — generally 5–15%, far less than oolong or black tea but more than green tea's near-zero.

The defining cultivar is Fuding Da Bai (大白, "Big White"), which produces the unusually large, silver-downy buds that become authentic Bai Hao Yin Zhen (Silver Needle). The Zhenghe Da Bai sub-variety produces a slightly different white tea character. Beyond Silver Needle, the same Da Bai material with more developed leaves produces Bai Mu Dan (White Peony) and the lower-tier Shou Mei and Gong Mei grades. Aged white tea has become a substantial category over the past 15 years — properly-stored Fuding white teas develop honeyed, slightly medicinal character over 5-10+ years that's distinct from any other tea aging trajectory. Pressed white tea cakes (similar to pu-erh format) have become collected items with vintage-year pricing.

Key processing steps

1. Hand-pick downy buds (Silver Needle) or buds with one young leaf (Bai Mu Dan)
2. Extended natural withering on bamboo trays (24–72 hours)
3. No pan-firing, no rolling — minimal intervention
4. Final low-temperature baking to stabilize moisture
5. Optional pressing into cakes for aging
