R/smoking is a dedicated forum to smoking meat. Might ask this there. I've used red oak and white oak, but never blackjack. I have a lot of blackjack trees on my property but the things are so dense that they throw sparks when I run a chainsaw through it, but I've never used it for smoking. I've used Blackjack for grilling for many years since it's considered a scrub oak and readily available here in NE Florida. I recently started using it as a smoking wood in my new Land 60D. The several briskets, pork butts, and chickens have turned out great. FWIW I leave the bark on. Mar 19, 2014 Red oak makes a fine grilling wood, and the smoke is especially suited to ribs and beef. Popular varieties of red oak include the Coast Live Oak or California Red Oak (Quercus agrifolia), Blackjack Oak (Quercus marilandica), Southern Red Oak (Quercus falcata), Water Oak (Quercus nigra), and the Pin Oak (Quercus palustris).
Quercus marilandica, the blackjack oak, is a small oak, one of the red oak groupQuercus sect. Lobatae. It is native to the eastern and central United States, from Long Island to Florida, west as far as Texas, Oklahoma, and Nebraska. There are reports of a few isolated populations in southern Michigan, but these appear to represent introductions.[5][6]
Quercus marilandica is a small deciduoustree growing to 15 meters (49 feet) tall, with bark cracked into rectangular black plates with narrow orange fissures. The leaves are 7–20 cm (3–8 in) long and broad, and typically flare from a tapered base to a broad three-lobed bell shape with only shallow indentations. They are dark green and glossy above, pubescent underneath, and often remain attached to the twigs through the winter after turning colors from red to brown in the fall. The acorn is small, 12–20 mm (0.47–0.79 in) long and 10–18 mm (0.39–0.71 in) broad; like other red oaks, it takes 18 months to mature.[7]
The blackjack oak grows in poor, thin, dry, rocky or sandy soils where few other woody plants can thrive, usually on low ground, from sea level up to approximately 2,800 feet (850 meters) in altitude. Some commentators say that it does not have the beautiful form of many oaks, but is nonetheless a valuable tree for growing in problem sites.[8] Some say that the tree is 'tough but ugly', but also underappreciated.[9][10] At times the tree has even been actively eradicated to provide room for trees deemed to be more commercially valuable.[11]
It is sometimes an understory tree in pine stands on sandy knolls in the southeastern US. Along the coastal plain of New Jersey the probability of finding this species is increased in relatively sunny, open areas such as those near coastal salt marshes. It often occurs near scarlet and post oaks as well as pitch pine; understory companions include winged sumac, bracken, sweetfern, and bayberry, and can be found as far north as parts of Ohio[12] and New York.
A variety, Quercus marilandica Münchhausen var. asheiSudworth,[7] grows in the western portions of its range – northern Texas, Oklahoma, and into southern Kansas. In this area, blackjack and post oak form a semi-savanna area composed of forested strips intermixed with prairie grass glades along the eastern edge of the southern Great Plains. This semi-savanna is known as the Cross Timbers.[13][14][15] Scrub forms of Q. marilandica dominate on many chert glades along with Q.stellata in Arkansas's Ozark plateau.[16]
Blackjack oak sometimes hybridizes with bear oak (Quercus ilicifolia), forming a hybrid known as Q. × brittonii.[17]
Blackjacks in the Cross Timbers can grow from 50 to 60 feet (15 to 18 m) high with a trunk diameter of 16 inches (41 cm), but seldom reach more than 40 feet (12 m). The leaves are from 4 to 10 inches (10 to 25 cm) in length and about the same width. Blackjack acorns provide food for both whitetail deer and wild turkey. Blackjacks may, however, cause tannic acid poisoning in cattle.
The wood is very dense and produces a hot flame when burned, which functions as an excellent source of heat for barbecues and wood-burning stoves. However, the wood is not desirable for wood fireplaces because the heat causes popping, thereby increasing the risk of house fires.[18]
Traditionally blackjack wood is used as both a fuel and smoke wood for barbecue in Oklahoma.
