Kill, gut and quarter the animal in the first 4 hours. Then head home. Once home, we turn on the 15 cuft spare refrigerator and put the meat in while we prepare the kitchen for butchering. All the counters, cutting boards and knives get bleached. Front quarters come in first - bottom of the feet are cut and wrap for stew meat. Roast that come out of the top of the quarter are cut, wrapped, weighted, and labeled for pot roast. Any small trimmings go into a bucket for burger. Then the next quarter, then the first rear quarter - here you get stew meat from the bottom, roasts and steaks - all get cut, wrapped, weighted and labeled. When the rear quarters are finished - the sirloin is cleaned of gristle and cut, wrapped, weighted. Then the tenderloins are checked, cut, wrapped, weighted an labeled. The meat that is left over - goes into a freshly cleaned and bleached 5gal pail - I then drive it to a local butcher who adds suet and grinds it - only takes 20 minutes. Then back home to cut, wrap, and label the burger. Then clean the kitchen, turn off the spare fridge and clean it. Whole process - for a caribou - just takes 1 day. For a moose - we usually quit around 10pm and only have the front quarters cut, wrapped and labeled. Then we get up and finish off the rear quarters and body meat the next day.
We have never dropped an animal off at a butcher. I've butchered deer, caribou, moose, and buffalo in small kitchens. The 'trick' to tasty meat butchered at home - keep everything hospital like clean - and never put more than 60lbs of meat in a freezer per day. We have three freezers - so - we can put up 180lbs a day. Doesn't matter if you have a 9cuft or a 28cuft - generally they all have the same compressor and only accept 60lbs of meat per day - if you read the manual. It's the guys that pile in a couple of hundred pounds of salmon, halibut, or meat all at once - and do not realize the meat acts as an insulation barrier and it can take a week or more for the stuff in the middle to freeze!! Yikes! You have the put the meat in, leave air spaces for the cold to get to it all.
People who hang meat in their garage - unless it is kept at exactly 42.5F all the time 24/7 it is not a help. Lower - nothing happens. Hotter - you get bacteria, foul odor and foul liver like taste. Needs to be exactly 42.5F for the enzymes to break down and age the meat.
Hanging does not make bad meat taste good. But hanging improperly will make good meat taste bad.
