Well we have talked about British and American styles of making tea,
now the third in the occasional series is Grandpa Style.
Bet you didn't know that was a style of making tea.
Grandpa style is much the way you see in the picture.
The water is added throughout the day for a constant source of tea.
My "live-in gardener" observed this when he traveled on the train in China in 1986.
The name "grandpa style" hadn't been coined then, but ultimately this is where it came from.
The loose tea is tossed in a jar and hot water is added throughout the day.
I understand that on the train they would come through with a kettle of hot water
to do just that, replenish the tea with water.
I believe the "grandpa style" titled was coined fairly recently, possibly by bloggers.
The below link had quite alot of information on this style of sipping tea
and rather than repeating the information you can visit there for more details.
Do you ever sip tea "grandpa style"?
