  Shizu 7132 (Sizu 7132?)
Also called: Shimoshirazu, Sakura-kaori
Developed: at the Shizuoka tea research center in the late 60s to early 70s from Yabukita seeds
Cultivar Type: includes cultivars such Yamakai, or Kurasawa (less famous but the father of Kôshun, which is well-known).
Prefecture: Shizuoka (静岡県)
Registered: not officially registered, no official name
Features:
  • High resistance to frost, so was first planted in mountain areas.
  • Ideal harvest period is short, requiring lots of people out in the field at once.
  • Thick stems, making rolling difficult so was abandoned for a time.
  • Interest in this cultivar reviving due to unique fragrance (high concentration of coumarin, making a sweet scent like pickled cherry leaves used in Japanese pastries called “sakura-mochi”).
  • Quite rare, mainly used in Shizuoka.

Due to how Japanese is translated into English by various people, this tea might be the same as Sizu 7132. Have been unable to determine for sure. If you know, please comment on this page and I will update (with a credit to you).

  Sugiyama-yaeho (杉山八重穂)
Old Name: 二芽の)八重穂
History: Shizouka conventional selection (静岡在来選抜)
  Sunrouge (すんろうげ)
Name meaning: “red bud reaching to the sun” (“rouge” is “red” in French)
Prefecture: Ibaraki (茨城県)
Registered: 2009
History: Camellia taliensis, which is still being used in Yunnan for tea making, and Okumusashi (おくむさし) were bred. Out of that hybrid, a cultivar was developed: Cha Chuukanbohon No. 6 (茶中間母本農6) – loosely translates as “intermediate female tree, agriculture number 6.”

This cultivar has a high anthocyanin content but is hard to cultivate and has low growth, so different seeds from natural crossings of Cha Chuukanbohon No. 6 were selected and nurtured and the best tea plant was selected and named “Sunrouge.” It has a higher anthocyanin content than Cha Chuukanbohon Nou 6.

Hybrid of: Camellia taliensis and Okumusashi (おくむさし)
Features:
  • Normal budding, harvested same time as Yabukita (やぶきた)
  • Buds reach a red/purple tone at their peak but lose that color if not harvested that day
  • Adding lemon juice or other acidic liquid will lower the pH and change the liquid color
  • Plant is medium type with more branches than typical cultivars
  • Slightly resistant to anthracnose (Discula theae-sinensis), highly resistant to gray blight (Pestalotiopsis longiseta) and relatively low resistance to brown blight (Glomerella cingulata)

Anthocyanins are polyphenols found in plants; they are water soluble pigments that range from red, purple or blue, depending on the pH. They are in eggplants, blueberries, raspberries, pomegranates, and many other fruits. They don’t affect flavor but are said to have some health benefits.
