We're happy to help. The leaves of sencha will stay wet all day in a covered kyusu or hohin. I probably wouldn't steep them after 8 hours, to be more precise. It seems to me that tea steeped in quick succession tastes better than tea that's been left out. I think some oxidation takes place and begins to hurt the flavor and fragrance of the tea. Essentially, you brew the tea until it looses its flavor. The times I submitted above are estimates that work well for me. Eventually you will get good enough that you won't need to time it, especially if you get into oolong teas.TripleB67 wrote: ↑Tue Apr 28, 2020 5:33 pmI guess you can have however may infusions until the flavor runs out of the leaves or the time you have to steep them gets ridiculously long? So if I leave them in the kyusu for say a day...will they dry out or will they stay wet until I use them again the next day?
I'm happy to hear you are familiar with using metric. It makes things so much easier. Most people will give whole gram units for weight but I know that the grams feature on my large kitchen scale is off by +-1 gram. When measuring tea, it helps to have an accurate gram measure, especially with matcha. Being off by a gram will make a significant difference.TripleB67 wrote: ↑Tue Apr 28, 2020 5:33 pmNo worries on the metric measurements. I modify tennis racquets in my spare time so I'm used to working with grams because I can be more exact with my modifications to the racquets. I bought this scale to use with my tennis racquets (although I only paid $25 for it): https://www.amazon.com/dp/B002CM6TVI/r ... =UTF8&th=1. It's really accurate but obviously won't fit into my pocket to take with me. I'm teaching from home now because of Covid-19 so luckily I can experiment with various teas within the comfort of my home. Edit: of course now that I look at the scales you mention, they are accurate to .01 gram and mine is only accurate to 1 gram - I guess I better invest in a more accurate scale![]()
There are ways to guess the weight of oolong by eye but it is nearly impossible to do this with sencha and matcha, in my opinion. I know that two scoops to approximately 70 ml of water is what's recommended for making usucha (the more typical matcha preparation) but I have found that the weight scooped to matcha to be inconsistent because the powder can have more or less air in it. While it lacking in sophistication, I use a scale for these two teas to be consistent. My Japanese tea has improved quite a bit since then.
Cheers!
