Understanding the Difference Between Sencha and Gyokuro

Japanese Organic Gyokuro & Sencha

From Cultivation to Brewing — Discover the Five Distinctive Features

Even those who enjoy Japanese tea are often unaware of the subtle yet significant differences between sencha and gyokuro.

In this section, we provide a clear and concise explanation of five key characteristics that distinguish sencha and gyokuro.


Cultivation Methods

Even when grown from the same tea plant, sencha and gyokuro become distinctly different teas due to variations in their cultivation methods.


Until the New Shoots Emerge

After the New Shoots Unfurl

Time of Harvesting New Shoots

Fertilization

Sencha

Cultivated under direct sunlight

Continues to grow under the sun

Harvested under the sun

Carefully administered, high-quality fertilizer in optimal amounts

Gyokuro

Grown under the sun

 

Shading cultivation* begins when the first one or two leaves start to unfurl.


From that point, the plants are gradually shielded from sunlight in carefully controlled stages. Over a period of approximately three weeks, the level of shading is progressively increased until about 98% of sunlight is blocked. In this low-light environment, the tender new shoots develop, resulting in the rich, umami-packed flavor characteristic of gyokuro.

 

Harvested under 98% shade

 

Because the plants are grown under shade, gyokuro requires more fertilizer than sencha.


Producing organic fertilizer suitable for gyokuro is particularly challenging, and only experienced, highly skilled tea farmers are capable of crafting it successfully.

 



 

Differences in Nutritional Content

Although sencha and gyokuro may appear similar, their nutritional profiles differ significantly.
