What does XT stand for?

Now in a newly revised and substantially expanded edition, "When Technology Fails: A Manual For Self-Reliance, Sustainability, And Surviving The Long Emergency" by engineer and building contractor Matthew Stein provides a comprehensive and thoroughly 'user friendly' instruction guide to preparing for both temporary and extended technology collapses and dramatic adjustments necessitated by local phenomena and global environmental trends ranging from the inevitable diminishment of petroleum as a source of energy, to climate change, to economic collapse.

The company's extended technology also means these flavourings are available in spray dried and liquid forms.
