Ahh, another coffee aficionado, and I have to tell you the best cup of coffee I ever had came out of a porcelain percolator that set atop a wood campfire. It was about 30 years ago, but it's still the best I ever tasted!
Thanks for the info on the charcoal & wood chips, I saw them at my brew store, seen where they've been used in brewing other liquors, and would like to give it a try in a small batch.
Not a big fan of the "Americano" style drip type coffees. To watery for me.
Turkish/Arabic coffee is devine, if sweet.
Whether your fave choice is about the maker or the origin of the beans, I don't know (i don't believe it when I hear "America makes the best coffee" - Italy and the Arab world have that pegged IMO/experience. Luckily for all of us, the US is a good, diverse place, so it's easily found and I don't necessarily mean the coffee fascists of Starbucks either
). And I routinely get ready ground/roasted, Lavazza Gold.
Enough of the silliness
, with oaking, if you can find some cooperage quality oak, then mill/grind/plane it, as it can go in like that and simulate barrel fermentation if in primary.
With oak chips, staves, spirals etc, those normally have origin and toast levels. I don't recall any maximum but a bit of searching should give you detail on which you might prefer for all of the above.
It can be a bit of a lottery, but I'd suggest that you focus on the signs of "over oaking" as it's easy to add more, but a bit of a Bugger to remove too much......
