Special features in location, cultivation & processing
Ibaraki Prefecture, located north-east of Tokyo, is one of Japan’s lesser-known tea-growing regions. The flat landscapes around Jōsō, where our partner tea farm is located, lie just 15–20 metres above sea level. Dense surrounding forests provide shelter from the wind and create a balanced microclimate, while the region’s northerly location plays a decisive role in shaping the character of its teas. Winters are considerably colder than in the southern tea-growing regions, slowing the plants’ growth and resulting in leaves that are generally thicker and richer. This makes them particularly well-suited to processing as Japanese black tea (Wakocha), due to the depth and structure of the leaves.
This Wakocha comes from the second harvest in July and is made from the Fukumidori cultivar. Processing follows several carefully coordinated stages.
Picking (July, second harvest): The later-harvested leaves are more robust and aromatically concentrated than those from the spring harvest.
Withering: The freshly picked leaves are gently allowed to lose moisture, making them soft and pliable.
Rolling: Rolling breaks down the cellular structure of the leaves, bringing enzymes into contact with oxygen.
Oxidation: This is when the characteristic aromas of Wakocha develop. In Ibaraki, this process often produces sweet, rounded profiles with very little astringency.
Drying: Heat is applied to halt oxidation and stabilise the finished tea.
Single Origin
This tea comes 100% from the above-mentioned tea fields in Ashikita.
