Plopped a nondescript teabag in the cup, and poured boiling water over it. Teabags are notoriously a bit of leaf (if any) and teadirt, so I only let it steep 3 minutes. Took a deep breath and smelled the cup. Not much of a smell, but that doesn't necessarily mean anything.
Waited a few minutes for it to cool down, and then finally took a sip. Bitter. Somehow tasted dirty. Give it a few minutes. It might improve after it cools down a bit.
Not a chance. Just more obvious that the quality of tea in this bag is not remotely acceptable.
Sigh.
A terrible cup of tea.
