White oaks tend to drop every two to three years with the third year a bumper crop. If the whites arn't dropping then find the pin or sawtooth oaks. The tend to produce every year and are a close second to the white oaks as far as prefrence goes.
You can increase your quality and your mass production by fertilizing your trees. They can be trees on game management even. Go get some fertilizer spikes and place them in the ground about four feet from the base of the tree and next year the deer will prefer the trees you spiked. Also works with persimmon trees.
