Brewing in Zero-G — Why Chinese Tea Went to Space

Tea in space may sound poetic, but it’s rooted in science. During extended space missions, maintaining the physical and mental well-being of astronauts is vital. Traditional Chinese tea offers a low-calorie, antioxidant-rich beverage with calming effects — an ideal alternative to coffee or processed drinks.

In the Chinese space station Tiangong, astronauts have tested multiple varieties, including Longjing (Dragon Well) and aged Pu-erh. These teas were pre-packed in special infusion pouches to allow steeping in microgravity. Sipped through flexible straws, the astronauts described the flavor as “comforting” and “like home, in the sky.”

NASA and ESA have explored space drinks before, but China’s approach blends cultural significance with practical health benefits. Teas like Pu-erh may aid in digestion and help reduce stress — both valuable in confined, zero-G environments.

For tea lovers on Earth, this experiment also boosts appreciation for tea’s versatility. From ancient dynasties to low-Earth orbit, Chinese tea continues to evolve while staying true to its roots.
