What you have sounds exactly like what Adagio sells (their Puerh Dante
), which is a loose, cooked Pu-erh. This means the manufacturer took the loose leaves (called Mao Cha; similar to green tea), spread them out on a platform, repeatedly sprayed them with water and heated them (simulating the "fermentation" that usually occurs over time in a non-cooked Puerh), then packaged it and sold it. If they wanted to sell it in a compressed form (stores better), they'd do that at the end, as well.
Here are a few links to information on Pu-erh:
Hou De's Pu-erh Information (from a supplier)
Wikipedia entry for Pu-uerh Tea
...probably several more than that, but those are my favorites.
