"John" asked:

Ever had any luck with Darjeelings? I really don't drink much black tea
besides them, and I've never been able to get a good second steeping out
of
them. Am I doing anything wrong (boiling water and 30 seconds additional
steep time)?

I often get a second steeping out of Darjeelings, but it's not the same as
the first. Although it may still be quite good.

I think Dog Ma covered the basic issue well. There are certain compounds
that steep out of tea quickly and will appear in much greater concentrations
in a first steep than a second, and other compounds that will diffuse during
both.

Just don't expect to get the same results from both steepings.
