I've been told from another source that TEA is very good at coverting
alkali tap water to slightly acidic. A pot of tea will treat a
gallon of water.............

A British Dental Journal article I found on line records an experiment
using tea of pH 4.9, so I assume they take that as typical: I doubt if a
pint would be enough.
