Quick interjection, where would one find coshell? Maybe a dumb question, but does it actually impart a coconut flavor? I have issues with coconut anything.
No, Coshell and Charcos do not impart any coconut flavors.
A couple years ago a guy posted on the BBQ Brethren site looking for folks to review Coshell. I received a few small 3.3 bags of it and to be honest, it wasn't enough to do any kind of long cooks with such a small amount, so I only grilled with it. It takes a little longer to get lit and to temp, but it does get hot and extinguishes when the vents are closed off leaving you with quite a bit of fuel to reuse.
I was pleased with it and gave them a favorable review and they sent me a few more large bags which I used in my Backwoods, BGE's (the horror!) and 22" WSM's with great results. I eventually found some at a local Lowes, but they didn't last long in stock.
Coshell then offered teams a "sponsorship" which basically amounted to a 10% discount if you ordered through Lowes (retail) it covered shipping. Not a big deal for me if I can't grab 'n go.
We took some Charcos and Coshell to an Evergreen Eggfest sponsored by the local Big Green Egg and Wicked Good distributor in hopes of getting them to pick them up. A couple Reps had already tried Coshell and complained of excess ash in the domes on high temp cooks (something I had experienced, but didn't think it was an issue) and they poo-pooed it. In the end, they had their hands full selling containers of Wicked Good and overpriced royal oak BGE Lump to take on anything else.
I use the Charcos in my BGE for baking and pizza, burns hot and super clean.
