FYI, the taste differences become far more obvious with better quality teas. Darjeeling, being a more subtle (and posh) tea show this strongly. It’s also a lot less tolerant of poor brewing.
For best results, don’t cheap out, and look up optimal brewing instructions.
Before kids, microwaved tea is an absolute travesty. After kids, it’s an unfortunate necessity.
I personally have cheap(ish) teas that priduce a drinkable cup. I also have the good teas that deserve more care and attention.
If you’re interested, these guys provide the best tea I’ve found so far. (They also supply a number of the best tea shops in Bath). It’s definitely not cheap tea, but I currently have several kg of it in the house 😅
