Gua Feng Lao Zhai is a benchmark in Yiwu tea, with prices recently soaring. Excellent mountain tea grows in Guo You Lin (state-protected forest) at 1400-1600m. Ancient trees produce thick, dark leaves with white hairs. The golden, clear liquor has an elegant floral fragrance. The tea soup is sweet, viscous, smooth, rich, full, with a strong sweet aftertaste, ranking among the finest Pu’er teas.
