I just opened a 100g bag of tea from Maiko and the package is resealable. I would have usually poured the 100g into a tea tin and would open/close that tin often as I worked through the tea. Light bulb went on and I thought it's probably better to only pour in 50g, and leave the other 50g in the original bag, with the air pressed out, and resealed. I have to assume this is preferrable but will ask - am I'm missing something with this approach?
Also, when the 100g bag isn't resealable, I was just thinking that it would make sense to pour 50g into one tin for immemdiate use, and the other 50g into a 2nd tin that I wouldn't open again until I'm done the first tin. Again, have to assume this is a fine approach but I will ask if I'm missing something?
