If your idea of a good cup of tea starts with plain tea bags from
the grocery store, you are likely missing out on truly superior tea.
Before I explain why loose tea is better, I just want to let you
know that I am mainly talking about generic supermarket tea bags. There
are some excellent bagged teas out there, made up of whole tea leaves.
Quality tea merchants often carry bags as well as loose.
The main difference between loose teas and bagged teas is the size
of the leaves. That's what effects the resulting cup of tea. Tea leaves
contain chemicals and essential oils, which are the basis for the
delightful flavour of tea. When the tea leaves are broken up, those
oils can evaporate, leaving a dull and tasteless tea. Typical tea bags
are filled with the tiniest pieces of broken leaves, called fannings.
Loose teas are typically whole leaves or at least large pieces of
leaves.
On top of the leaf size, there is also the space factor. Tea leaves
need space to swell, expand and unfurl. Good water circulation around
the leaves is important, which doesn't typically happen in a cramped
little tea bag.
A quick aside: the declaration of "Orange Pekoe" that you'll find
on boxes of tea bags doesn't refer to the flavour or kind of tea.
Orange Pekoe is actually a grade of tea. It's a good grade, but not a
great grade. The grade is based on leaf size, but even Orange Pekoe tea
is an inferior tea to a true whole leaf tea.
Even if you prefer a simple cup of black Keemun, or Assam (which is
the major component of most bagged teas), try getting your tea loose
instead of in bags. If you enjoy a change now and again, you can get a
wide variety of teas in bags, but there are many more to choose from if
you shop for loose tea.
