TEAAll brands of plain unflavoured tea and plain unflavoured tea bags are produced chametz-free but must be purchased before Pesach.
HERBAL TEAHerbal Teas come in two forms. The first is pure leaf with no additives such as pure chamomile or pure mint leaves. These are acceptable for Pesach. (Many people have a custom to use only tea made under supervision). Herbal teas that come with multiple ingredients including flavours should not be used for Pesach unless under a reliable kosher certification.
