if u kill a buck in the rut, Cut the tarsal glands off of your buck. Put them in a quart jar. Try to get some off his urine when you gut him and put that in the jar with the glands. Get some everclear 190 proof or the highest proof u can find and pour in enough to just cover the glands. Put on the lid and shake and up every couple months until the next deer season. The longer it sits the better it gets.
