The full guide
Read straight through, or dip into the sections that matter for your next smoking session.
The single most common mix-up in home smoking: buying chips for a cold smoker, or dust for a BBQ. They look like the same stuff at different sizes - they are actually fuels for two different machines. One rule sorts it forever: dust for cold, chips for hot.
Putting the grades into practice? See how to use a BBQ smoker box with coarse chips and how to use a cold smoke generator with dust.

Why chips will not work cold
A cold smoke generator relies on the fuel itself smouldering slowly along a maze - only fine wood dust packs tightly enough to creep along at that pace. Chips have too much air between the pieces: they either go out or flare, and either way your 12-hour salmon session dies at hour one.
Why dust will not work hot
Over direct heat, dust flashes to ash in minutes and can catch fire in a smoker box. Fine chips release smoke steadily in a stovetop oven; coarse chips last through a proper barbecue. Grade to kit, always.
What to buy
The right fuel for each job
Dust and chips questions, answered
Can I grind chips into dust?
In theory; in practice you get uneven grit that smoulders patchily. Milled dust is graded for an even creep - it is the one corner not worth cutting.
Do I need both?
Only if you run both methods. Hot-only households need chips; a ProQ owner needs dust; the ambitious need one bag of each and a free weekend.
Does flavour work the same in both?
Yes - apple is gentle and hickory is bold whether dust or chip. Our best wood chips guide maps flavours to foods, and the same map applies to dust.
