What are the options available today?
I know that they originally came in two styles, steamed and un-steamed... is that still the case today?
Who are the modern makers? I've seen a few coming out of Hubei and Hunan... are these any good? How do you tell the high quality ones from the poor quality ones?
I've also heard that they still make them in Georgia. Is that true?
Are there any other places making tea dust bricks? (Uzbekistan? Fuzhou in Fujian? Somewhere else?)
Finally, any advice on preparing the stuff? Just grate some off a corner to make a zavarka concentrate and then add hot water? Or is there a special way?
