Oh, no! Not another tea bigotry thread? Oh, well, here goes. Let the flames begin:
Dr Stu is a bit unscientific. Volume of water in mug vs styrofoam cup is different. Styrofoam tea is stirred, mug tea is not. Hardly a fair comparison. Though a fair comparison is hardly needed in order to know that styrofoam cups are awful.
For me, teabag in mug, 2-3 minutes, but with some stirring to agitate the tea leaves (dust) in the bag so they all get a good exposure to the hot water. Dr Stu’s teabag in a mug was just left as it was - with the clump of tea in the bag undisturbed by any stirring. With a good stir or two (when water added and again maybe 60 secs later) the tea gets nicely brewed. It sort of emulates (within the limits of the situation) the way loose tea leaves get to swirl brownianly in a teapot.
For those (I’m looking at you @Bobo and @RexDart) banging on about temperature of water for different teas, did you notice that this video was explicitly about making a good old British cup of tea in a mug with a teabag (and by clear implication, a bag full of typical British tea dust - Typhoo, PG Tips, etc. - not some other fancy tea variety, which if it were in a bag would probably have you equally indignant).
Five minutes? Always? For every variety of tea? NO.
Nobody said that!
I still get perpetually pissed off by places that offer a cup of hot water and a teabag on the side - water being too cold by then. I did not order a “tea making kit” I ordered a cup of fucking tea. If you use teabags, that’s fine, just put the bag in the mug and pour the BOILING water over the bag - never add the bag to the already cooling water.
And @Miros - yeah, 30 seconds is a sick joke (almost certainly played for the purpose of the video), but in a cup with that small a volume of water it may not have been as bad as it might.
