lol i wondered why i looked so wrong but couldn't put my finger on it. truthfully though: "tee" would be the proper spelling in my native language and i haven't had a cup of tea yet so ¯\_(ツ)_/¯
do you mind me asking about the amount of tea you have used as well as the time you let it sit for?
most black tea like darjeeling and blends of breakfast teas taste very similar if brewed too strong (i.e. too much tea or too much time).
i like to use about a tee spoon full of tea for a mug size and let it sit for about 3-4min max.
