Due to the fact that a smoker barrel with a full load of charcoal will normally burn for anywhere from to 12 hours, I’ve found that wood chunks work better than wood chips. The normally smaller, thinner wood chips will burn up much faster. Three inch diameter limbs broken up into quarters make good sized chunks that will last almost as long as your charcoal. Just place a few handfuls in your wood chip holder and start smokin’!
Warning: Make sure you soak them in water beforehand to avoid a flame up.
