RIZHAO,China,March 17,2025 -- A news report from chinadaily.com.cn:

In the northern reaches of China,the brisk sea winds and harsh winters have given rise to a remarkable phenomenon – the renowned Rizhao green tea.

At 35 degrees north latitude,the direct angle of sunlight gives the Rizhao tea plantations an average of 2,600 hours of sunshine annually. The combination of the salty and humid sea breeze from the Yellow Sea with the undulating terrain of the Yimeng mountainous area creates a distinctive microclimate.

Racing against time: Northern tea crafting thrives against the odds

At daybreak,the dew-kissed green leaves must undergo a transformation within three hours. The moment the 220 degrees C iron pot begins to release white smoke,the tea master plunges his hand into the midst of the green leaves,tossing them at a rate of two times per second,a 40 percent increase in speed compared to traditional methods in southern China. Additionally,a gentle press and slow kneading take the place of heavy pressure and rapid rolling,preserving the integrity of the bud and leaf while creating the precise cracks in the waxy layer,which is what leads to the tea's signature chestnut fragrance.

Moreover,the denizens of Rizhao have repurposed air-raid shelters into constant humidity workshops to combat the capricious coastal climate. The introduction of modern freeze-drying technology further allows the fresh and crisp spring tea to be preserved before the summer deluges.

Forged by cold and sea: The natural evolution of Rizhao tea

Rizhao's frigid winters activate the cold-resistant genes of the tea trees,while the salt content in the sea mist fortifies the cuticle layer of the leaves. This natural selection process led to a 30 percent increase in the cold resistance of northern tea compared to its southern progenitor. Furthermore,tea trees that have withstood extremely low temperatures exhibit a 22 percent surge in polyphenol content in the subsequent year's spring tea.

A taste shaped by the elements

Rizhao green tea offers a crisp initial note,a bittersweet mid-palate,and a sweet finish. As the tea broth cools to room temperature,the vapor condenses into delicate golden rings on the cup's inner surface,serving as tangible evidence of the 15 percent higher polyphenol content in northern tea.
