Red espresso is made by preparing the Aspalathus Linearis shrub, commonly known as the source of rooibos (or "red") tea, to be filtered through an espresso machine http://www.coffeeandteafestival.com/newsletter/aug07.html.  When this patented form of the rooibos plant is filtered through an espresso machine, it results in a tea with a saffron crema.http://www.capeargus.co.za/index.php?fSectionId=342&fArticleId;=3100474

Extracting tea through high temperature and pressure can be convenient for commercial use. For the individual it is slightly more expensive because it requires an espresso machine. Just like with coffee espresso, this extraction process results in a tea with concentrated flavor. There are pressurized machines being developed specifically for tea extraction.http://www.patentstorm.us/patents/6220147-fulltext.html.
