Loose leaf vs tea bags
A format difference that is really a leaf-size difference. The trade runs in both directions, and the usual framing of one as compromised misses what each is built for.
What is being compared
Why these get confused
The common claim is that bags contain 'dust and fannings' as though those were sweepings. They are graded particle sizes, chosen because they extract quickly in a confined bag. The real limitation is that a cut leaf cannot be re-infused.
Point by point
| Aspect | Mug infuser brewing | Tea bag brewing |
|---|---|---|
| What is inside | Whole or large-piece leaf that expands several times over. | Usually cut or CTC leaf, sized to extract fast in a confined space. |
| Room to expand | Depends entirely on the basket. Too small a basket is the commonest cause of weak loose-leaf tea. | Little, which is why flat bags contain small leaf. Pyramid bags exist to address this. |
| Consistency | Variable — the point is that a garden and a season come through. | High. Portioned, blended and engineered to taste the same every time. |
| Re-infusion | Usually a second cup, sometimes a third. | One. Cut leaf gives everything it has at once. |
| Convenience | Slightly more work, and a basket to rinse. | The highest there is. No strainer, no measuring, nothing to wash. |
| Where the quality gap really sits | In the grade of leaf you chose to buy. | In the grade of leaf the packer chose to buy, which is a commercial decision about cost rather than anything the format imposes. |
The short answer
Bags are a delivery format that does its job well; loose leaf has more to give and asks more attention. A whole-leaf pyramid bag and a basket infuser give similar results, which is the test that settles it: the gap people notice is between cut leaf and whole leaf, and that is about what was bought rather than how it was brewed. Anyone moving from one to the other should expect to use more leaf than looks right and give it more room than the mug basket allows.
