Fairly heaping 2.75 grams
The scale is accurate as I also just weighed a dime to 2.3 grams.
I'll start with my conclusion: As usual, Chip's information is good.
I decided to do my own weighings with a new scale:Enter my new scale:According to wiki.answers.com a U.S. Quarter weighs 5.67 grams. This is where my directly out of box new scale is started from:
I had the intuition that shape matters. The Sakura Sencha
green tea leaves are rolled into linear shapes and a round teaspoon may not fit as much as an oblong teaspoon. I did 3 weighings, one per each of these differently shaped teaspoons:
I started off with the cheapo, battered, round, white plastic teaspoon I use at work, where I do most of my tea drinking:I got 1.72 grams per teaspoon:
Next, I moved on to a round steel teaspoon with a wider bowl:I got 1.85 grams per teaspoon:Finally, I moved on to a steel teaspoon with an oblong shape bowl:I got the highest weight, with the widest teaspoon, at 1.93 grams per teaspoon:
So, to make a cup ( 8 fluid ounces ) of Sankura Sencha Green Tea using 0.6 grams of tea leaves per 1 fluid ounce of water, I would need 4.8 grams of tea leaves.
Dividing that by the 1.72 grams per my cheapo plastic work teaspoon I get 2.79 teaspoons.
That sounds about right. Before I got the scale I found 3 cheapo plastic teaspoons to be slightly too strong and 2 of those teaspoons to be just about right.
I started off experimenting with 2 - 3 teaspoons per cup, because I had a reference point of where to start my trial and error process, thanks to Chip, and his quote of 1.75 grams per teaspoon above.
That was the original inspiration for all of this. Not being a gourmand, I had no idea what 0.6 grams of tea looked like.
I don't know why other people got figures of up to 5 grams of tea per teaspoon.
Some people mentioned using other types of green tea, so actually using Sakura Sencha might matter.
As I saw from my own weighings, the shape of the teaspoon seemed to matter. The rounder teaspoons held less weight, possibly because of the linear shape of the tea leaves, some of which were wider than the bowl of the spoon, so fewer leaves fit into the rounder teaspoons.
Lastly, age of the tea might matter. Older tea might have more or less water.
I found that the O-Cha tea pot
I bought holds almost exactly 8 fluid ounces ( I used a measuring cup ), but they advertise it as holding "11 ounces".
The stuff I got from them is nice, I would buy from them again, but I think they could benefit from reviewing their posted measurements.
No offense or disrespect meant to anyone.
