It’s no secret that shading tea plants has a drastic impact on the flavour of tea. After all, it’s what gives matcha and gyokuro their characteristic aromas, powerful umami, and vibrant green colour.

You may know that some Japanese teas, such as matcha and gyokuro, are ‘shade-grown’, but what exactly does this entail and how does it affect the taste of tea? In Part 1 of this deep dive into shaded teas, we’ll take a look at the history behind this uniquely Japanese cultivation technique and also break down the types and practices of shading that are used today. Then, in Part 2, we’ll explore the biochemical processes that are at work within the plant and how they are responsible for the characteristic tastes and aromas of shaded teas.

While you may not have heard of Japanese black tea, or wakoucha, it once accounted for around 60% of all Japanese tea exports. Now, it is undergoing a resurgence, but with an emphasis on quality rather than quantity.

However, don’t be intimidated by the complexity and intricacy of the teaware setups of ceremonial tea practitioners or hardcore tea enthusiasts—at its core, tea is simple.

Hagi-yaki (萩焼), or Hagi ware, is a regional style of Japanese ceramics that comes from the area around the town of Hagi in Yamaguchi Prefecture, for which it is named. Since its development over 400 years ago, Hagi-yaki remains highly valued within the traditional aesthetics of practically all tea ceremony schools, with some of the oldest Hagi-yaki pieces declared National Treasures of Japan. Here's a look into the history and styles of Hagi-yaki.
