... popular to the extent as of among russian prisoners,
who brew from it so called "tchifir" - extremely concentrated and hence extremely strong tea.
Actually it is a kind of (soft) addiction and the tchifirists are true tea-addicts.

I don't know the answer to your question, but I'm interested in seeing how many American prisoners are going to respond to this...

I'm guessing that Pruno is more popular in american prisons, it sounds very delicious...

I didn't know they served tea in prisons... >.> <.< >.>

They, who have money, buy it in the prison shop or get it (via postal service) from outside (from "volia").

As for pruno ("bragha"). They make it too (secretly, of course). But the drinking of the tchifir is an unique and authentic rite.

I thought they only serve bread and water in prison.
