Tea bags get a bit of a bad reputation among people who take tea seriously. Some of it is fair. A lot of it is not.
The truth is that a tea bag is just a delivery method. It can hold excellent tea or terrible tea, and the bag itself can be well made or quietly full of plastic. The problem was never the convenience. It was what so many companies decided to put inside, and what they decided to make the bag from. Once you know what to look for, a tea bag does not have to be a step down at all.
So this is a guide to choosing well, for the days when loose tea is not practical and you still want a proper cup.
Start with the tea, because this is where most of the difference lives.
Cheaper tea bags are often filled with what the trade calls dust and fannings. These are the small broken fragments left over after the better leaf has been sorted out. They brew quickly and strongly, which is handy, but they lose the more delicate flavours and tend towards a flat, slightly harsh cup. It is the tea equivalent of the offcuts.
Better tea bags use larger pieces, sometimes whole leaf. You can usually tell from the bag. If there is room for the leaf to move and swell as it brews, that is a good sign. Tea needs space to open up, and a tightly packed little bag never quite gives it that.
Many bags are made with plastic. Paper ones are often sealed with a plastic that holds the seam together, and the premium looking pyramid or silken bags are frequently made entirely from nylon or another plastic. They look the part, but they are the worst offenders. A widely reported study from McGill University found that a single plastic bag steeped in hot water released billions of microscopic plastic particles into the cup. The research into what that means for us is still ongoing, but it is reason enough to pay attention.
So a good tea bag is as much about the material as the contents. Look for unbleached paper, and brands that clearly state the bag is plastic free. Plant based bags exist too, though even some of these are a little more complicated than they sound, so it is worth reading the packet rather than trusting the word natural on the front.
Whole or large leaf rather than dust. A bag with room for the leaf to expand, often a roomy pyramid made from paper rather than plastic. Unbleached, plastic free material. And ideally organic, since tea leaves are not washed before drying, so anything sprayed on them tends to stay. A luxury tea in a bag is not a contradiction. It just means someone has bothered to get all of this right, rather than cutting corners where they assumed you would not notice.
It is worth being straight about this.
Loose leaf tea is still the better cup, in most cases. You get whole leaves, full room to brew, and often several infusions from the same leaf, which makes it more economical than it first looks. You also see exactly what you are drinking. For anyone who wants to slow down and pay attention, loose leaf tea is hard to beat, and a simple infuser is all you need.
But good tea bags have an honest place. They are quick, they travel well, and at the office or on a busy morning they are simply easier. The aim is not to choose a side. It is to make sure that whichever you reach for, the tea inside is worth drinking.
A couple of small habits help.
Use water at the right temperature for the type of tea, the same as you would with loose leaf, and do not leave the bag in too long. Over steeping a bag, especially one packed with fine particles, pulls out bitterness quickly. Give it a gentle lift and let it drip rather than squeezing it hard, which tends to release the harsher notes. Small things, but they show in the cup.
A tea bag is only ever as good as the choices behind it.
The convenience was never the problem. Cheap leaf and plastic bags were. Choose one made with real, whole leaf tea in honest, plastic free packaging, and you lose very little by reaching for it. The best tea bags are simply good tea, made easy. And there is nothing wrong with wanting both.
