Wood aging / pre burning
hi there,
Here is a question about wood burning, I hope you can help me out. My smoker uses wood only (oak) since I was running out, I had to buy new wood. The tree has been cut down about a year ago, and stored outside. They cut up the tree last week. The wood is still to wet to start a fire. The best thing would be to let the wood dry, but that will take some time. Is it possible to dry the wood in the firebox (preburn?) Thanks, Adriaan The Netherlands |

Wood aging / pre burning
Hi. I"m new to barbecue, but I've been doing it continuously for a couple
of months, with very good results. I consulted with Bo McSwine at Bo's Barbecue in Lafayette, CA, a very successful barbecue restaurant in northern California. He uses an Oyler, not one of the electric models- just wood fired. He uses green wood, and swears by wood fires of green wood (he uses oak) for the perfect smoking conditions. He says that seasoned wood burns better, but you can run into moldy flavors, etc., and he likes the flavor provided by green wood. I have a plum tree outside, and I've been cutting down branches on occasion to use as smokewood. Ive been able to ignite it by first using a chimney full of lump charcoal as the starting heat source in the firebox. Green plum wood placed on top first smokes, then ignites, and from there I can feed more green wood as the initial green wood burns down. Certainly, oak cannot be that much different.

If you pre-burn down to coals, it will be plenty dry for your cooker. There are some people that prefer green over very aged wood anyway. You may have to vary your fire making technique a bit to accommodate the extra moisture so split it a little smaller and add small amounts more frequently. |

Wood aging / pre burning
thanks for your advise. after reading the advise, I will give it a go. start
fire, toss wet wood in the firebox (to dry, not to catch fire) when it is dry, us it. will keep some logs wet to see what it does for smoke.

Do you remember where that > might be?? > Piedmont I may have more, but here is some of what I found ************************* OK, I understand that it is getting harder for the gases and liquids to get inside the meat as the smoking process continues, but is there a point where no more smoke flavor is imparted to the meat? Danny Gaulden-- Even though the smoke flavoring gases and liquids may not penetrate the meat nearly as deep after a few hours of smoking, I feel they still continue to be adsorbed on the outer surface of the meat. The smoke flavor can become quite strong and bitter if the fire is not managed correctly, or it can be a positive addition to the flavor if the fire is well managed. Smoking beyond the 2-6 hour period definitely adds more 'smoke flavor' to the meat, and there is a great distinction in flavor between 'smoked until done' meats, and meats that were smoked for a few hours, then finished off with just heat, by being wrapped in foil and left in the smoker or put into an oven. When one takes a bite and starts to chew, the eater doesn't know if the smoke flavor is coming from the center of the meat, the outer third, or the outside surface. He just knows it tastes smoky. So, I feel that the 'continue smoking until done' process does add flavor all the way through the cooking process. To what degree this is attained depends on how smoky one wants their meat to be, and how well they manage their fire. This was from Kurt Lucas Creosote Buildup Creosote is simply unburned wood particles and condensed flue gases which deposit in the chimney (smoker) interior. The rate of creosote buildup is affected by residence time, smoke density, and stack temperature. Residence Time - Residence time is the time the smoke remains in the venting system. Residence time is affected mainly by flow. Flow is simply the amount of air moving through the chimney. Within certain limits, the greater the air movement, the lower the residence time will be. Abnormally high flow can result in turbulence, which can actually increase residence time. Low flow, usually caused by oversized flues, results in longer residence time and high rates of creosote buildup. The less time the smoke stays in the chimney, the less it can deposit on the walls. This is desirable for maintaining a clean chimney. Smoke Density - Smoke density is the amount of smoke produced by the fire. When combustion air is restricted, it causes incomplete combustion resulting in high smoke density. Creosote is simply unburned particulates and gases leaving the fire. When smoke density is high, creosote deposits will be high. Without smoke there is no creosote. If you can visualize an open campfire, it generally produces very little smoke because it has plenty of air to complete the combustion process. With complete combustion there is no smoke and no creosote. This is from the BBQ FAQ Danny Gaulden on wood-- Wood Storage Once the wood has been split, it must be stacked to dry or season. Drying occurs more rapidly ALONG the grain. Therefore don't stack the wood for drying until it is split. Avoid damp places or depressions where water will collect after a rainfall. The pile should be free-standing with maximum exposure to air and sunlight. A tarp over the wood pile in rainy season helps keep it dry. Green Wood Green wood can be as much as 65 percent water. Much of this moisture evaporates very quickly. In three months of reasonable weather (evaporation depends on temperature and humidity), the seasoning is half complete and the fuel value is 90 percent of what it will be when thoroughly dry; in two years the wood is as dry as it will get. There is an appreciable difference in BTU rating for woods burned green or air-dried. Completely dry hardwood has about 7850 BTU's per pound whereas green wood when burned loses over one-eighth (1200 BTU's per pound) in evaporating the moisture. It requires no work to let the wood sit for at least a year. In the process you are increasing the heat value, the wood will be lighter, ignite better, and produce less smoke and fewer sparks. Wood will dry faster if it is split. Much depends on the humidity and the weather in your area. In some areas in May and June, wood will dry rapidly, it will reabsorb water in July and August, dry out again in September, reabsorb water in October. Potentially wood can increase its moisture content if not properly stored. Drying can be hastened if the pile is stacked criss-cross for three months, then stacked in the normal parallel fashion. Green wood is easy to identify. Just split a piece. The core will look wet and shiny; dry wood looks dull and the saw marks are less pronounced. Green wood is almost twice as heavy as seasoned wood and will make a dull thud when two green sticks are hit together. It is hard to handle, hard to light, and burns slowly. Much of its energy is lost in heating, then evaporating the excess moisture. As wood dries, the moisture evaporates naturally and the wood begins to shrink. Wood, even when air-dried, is still has 20-25 percent moisture content. Since wood shrinks unevenly, cracking and checking of the wood occurs. Dried wood can be recognized by the weathered ends, and by the cracks which will radiate like spokes out from the heartwood. Buying Wood The delivery of wood is not yet a regulated business. Whether you are actually "taken" or not, you probably will think so. One delivery won't appear as large as the next, will be piled differently if at all, and may have assumed another name by the time it arrives. Wood is sold by the truck load, by weight, in cords, ricks, runs, or units. All this is as confusing to the wood-burner as to many dealers. Others simply take advantage of the fact that most homeowners don't know the difference between wood species or understand wood measurements. Wood usually is sold in divisions of a STANDARD CORD which is a neatly stacked pile eight feet long x four feet wide x four feet high covering 128 cubic feet. Since wood can't be stacked without air space, only 60-110 cubic feet of the 128 may be solid wood. (Usually it runs between 80-90 cubic feet with more solid wood content in round wood than split.) A FACE CORD is also called a RICK or a PALLET and is 1/2 a standard cord. There is a considerable difference in weight between woods; a standard cord of air-dried hardwood weighs 4000 pounds while a standard cord of softwood will weigh half that. |
