That's how the fermented Mextiza looks. I cut the brick in quarters and now it is very easy to shred with the fingers, and take pieces into the grinder. Now it is hard, some pieces look like wood, and must be grind properly.
I couldn't resist the temptation and I started smoking it. It burns fantastically well, and when left over the desk it doesn't take humidity from the air like normal unpressed bud. It looks like a piece of wood and its smoke is dense and aromatic. Increased material hardness causes a better grinding, and thanks to good grinding, it burns in a very regular, slow way. It tastes good for just a couple of weeks of curing, but it would become better in days to come if I wasn't smoking it already.
I love fermenting sativas. I don't think this one will last enough to make any comparison over time, but I understand that what I love, others can hate. Smell has nothing to do with mainstream bud smell.
