I can practically guarantee that people who say they hate tea haven't tried brewing any kind of loose leaf tea at the proper temp and time.

I got a 1kg brick of the cheapest loose-leaf black tea I could find for ~$3.50, and it's delicious. I drink it almost every day, I bought it in June last year, and I'm just now running low. I brewed a bag lipton black tea at work recently, took one sip and I dumped it the fuck out. Absolutely foul, that stuff.

So I can see why people hate tea if they've only ever tried cheap bags with boiling water
