I built a small walk in cooler. Use the CoolBot controler and keeps my small cooler around 34-36 deg. I hang whole deer for 7 days and like what im getting but next year thinking Ill go longer to try that out to compare tenderness.
I hang in my garage, open the door about 6 inches overnight once the lows are down into the 30’s then close it in the morning to trap the cool air in for the heat of the day, I also make sure and keep a fan blowing on the meat to keep air circulating. I hung my deer in November for 2 weeks that way. Temps varied from down in the 20’s to the mid 50’s. This is in southern Idaho and obviously there are regions of the country you couldn’t get away with this. Once temps are consistently below 40° I’ve hung meat for a month with no issues.
My only intent of "aging" is to allow rigor mortis (sp?) to do its thing before
detaching muscles from bone. Immediate boning seems to lead to tougher meat.
Though I have let a deer hang till I had mold growing between the hind quarters ( three
or 4 weeks) and I'd venture to say it was some of the best venison I've ever had.
I've been skinning and then wrapping with shrink wrap to keep a tough outer
layer from forming that needs to be trimmed off later as well as allowing better
cooling, especially around the neck area on elk.
I'll pull the front quarters off, shrink wrap or plastic bag them (or bone them out) immediately
as they get completely ground (except for the tastiest part of all: shanks). Not worried about toughness.
About three days and I'll either complete butchering or toss the rest in the freezer to be processed later.
Like Andrew12gauge, I hang in garage or shed as I usually wait till it's colder to go hunting.
Even if the days get into the 70's the nights get cool and I can open and close my garage accordingly
to keep it cool. Those warm days I believe it's crucial to get the hide off ASAP.
Every animal the last 2 years has gone through the ice aging process. Does it help? I dunno, but it sure makes me feel good! I usually do 10-12 days. Not sure what the “max” would be before spoilage? How long do you ice age and what’s the longest you’ve ice aged?
