I got a bag once. I did like I do with every new lump I get and start a small amount in a chimney so I know it's aroma before I cook with it. I couldn't even be outside with this burning, the smell was so bad and strong.
Others here seem to like it, but it wasn't for me at all. I threw the whole bag away.
WOW... that was my reaction when I tried mesquite.
1) The bag I had popped a LOT
2) and was made in Mexico
3) The smell was pungent and not the smell I'm used to in charcoal.
