God knows I am by no means a tea expert, but I'll attempt a quick review anyway.
2013 Chiran Shincha from Kaoru (O-Cha)
Steeping parameters: roughly 1 tbs for 250 ml of water at 76°-82°C (170-180 F)
First infusion: 1.5 min. The liquor is a bit dusty, with a shade similar to cinnabar green (7th column, the sixth from the bottom)
. This infusion is quite bitter (probably steeped too long), with grassy notes trying to emerge.
Second infusion: 30 sec. Still dusty, same tone of colour. Less bitter, much more grassy and... fruity? It's barely noticeable, but there's something more in this one.
Third infusion: 45 sec. Much cleaner and lighter shade of green. The bitterness is almost gone, leaving the grassy notes and hints of citrus/lime/whatever.
Fourth infusion: 1 min. The tea is fading away and with it its green colour and those indecipherable hints. The grassy and vegetable notes are still strong, though, which makes me think I could have done a fifth infusion.
Additional notes: I can confirm there's more caffeine than in common sencha and certainly more than in gyokuro. Nothing unbearable, but I felt a little buzzed for a while.
