Never heard of organic coffee? Philistine!
Then again where I am from, coffee is considered one of the major religions, so we have more choices here. (Let's just say it's relatively near where Starbucks got its start.) We actually have a pretty wide range of organic, shade-grown coffees available, but I expect it's not the same everywhere. It's definitely not in cans next to the Folger's. So just use what you can get.
About the wood ashes, supposedly hardwoods are the best, so oak is good. Pine and other conifer woods (fir, hemlock, etc.) are also fine to use contrary to what you may have heard. (I used hemlock, fir, and apple wood myself.) The key thing is to use clean wood that hasn't been treated with wood preservatives, i.e. burn some tree branches, not decking lumber. And never, ever use the ashes left over from grill charcoal. That stuff is
loaded with toxic chemicals...for that matter, I wouldn't eat food cooked over it.
So here I am, drinking my organic coffee, not eating food cooked over grill charcoal, eating organic vegetables. All so I can get lung cancer from smoking pot. Ain't life grand?
