Now I drink tea all day long. Flavored teas add to the variety and some fit the mood perfectly at times. I buy loose, or bulk, tea almost exclusively now. Tea bags are simple to use, but for me, they have a few problems. You get a premeasured portion of tea and I like to experiment varying the amount of tea I use to brew a cup or pot.
Loose tea is less expensive than the equivalent amount of the same tea in bags.
And, there are a lot more teas available loose. On the other hand, sometimes the convenience of a tea bag is great. It's easier to take tea bags traveling. And some teas I like are not readily available loose, if at all. Although I've drunk tea for decades, I didn't really know that much about it until recently.
