It might not be the tea. It could be the way it's being brewed.
Here are a few common reasons your tea isn't tasting its best:
Your water is too hot.
Delicate teas, especially green tea, can turn bitter when brewed with boiling water.
You're steeping it for too long.
Even the best tea can lose its balance if it's left to steep past the recommended time.
Your tea doesn't have room to open up.
Loose leaves need space to fully unfurl. The more they can expand, the more flavour they release.
A simple tea strainer gives your leaves the room they need and makes it easy to remove them at just the right time.
