I would apply the same rules to the skin as any meat.. 6 months to a year.. after that it'll probably get freezerburn, etc. Done!
Freezing till spring is totally doable, but try to time it so the temps are not higher than 70-75 degrees. A word of warning... braintanning is a monster as far as labor is concerned, and it's HIGHLY ADDICTIVE. That's why I want to get all the info and equpment I need ready now so when the temps start getting above freezing I can get on it and have time set aside for the labor.
The 4th pouring, I'd probably start off with, undiluted, then add the third pouring a week or so later and dilute it depending on how "thick" the liquor looks. Like I say, it's not a really specific method. I would think the 4th pouring would be thin enough to start without dilution. If there isn't enough liquor to cover the hide, add some of the third pouring. I don't think it'll be too strong. About like a cup of tea, and gradually increase to almost "soup", hard to see through.
(I think I answered all the questions lol) Hey, I'm just gettin' started. I have an entire list, just trying to spring 'em on you slowly, LOL. JK!
There are a lot of different opinions on how and what, but really it all boils down to chemistry and a little common sense. It has been said, "There are as many recipes and methods for brain (or bark) tanning as there are tanners" and I find this to hold true. There are lots of folks out there who have tanned thousands of hides and do it for a living. Whether they understand the chemistry is debatable, but they always reach the same end.
If we end with the same product, using different methods, then it must not be the method, but the underlying sciences that take place behind the methods.
