Wow, you guys are awesome! I would have nevere hoped for such response.
I think this brewing style should be more considered in tea sites... well, maybe it is but i couldn't notice because i didn't know it's called Grandpa Style, now that i google it, i get results pointing to this very site
The trick of not using a spoon makes a lot of sense, but i stll think i'm gonna use one for the first steep, otherwise the first half cup will be pure hot water!
The key trick of refilling when i'm half(or less)way through the cup is very interesting. Don't you think it would allow to use this style for stronger teas, like Ceylon or Lapsang Souchong? What difference would it make in taste, compared to the "traditional" brewing style? Sure as hell I will experiment, but i'm very interested in the opinions of cool guys like you
