I did a test last night on some Super-XX Pan 4x5 film that expired in 1980. I've shot several times with this film and get good results at ASA 25 so that's what I metered the shot at. I took the recipe from the web site I listed above and upped it to 750ml. I used 6 teaspoons of Washing Soda and 3 teaspoons of Vitamin C and 750ml of warm Budweiser beer.
A word of warning, if the beer you are using is not already flat be careful when you add the washing soda and vitamin C. I sprinkled a very tiny amount into the beer which resulted in a foam explosion. I then replenished the lost beer and put it into a large cooking pot to contain the explosion. Of course by this time the beer was pretty flat and not much happened when I added the rest of the powder mix. It took some mixing to get everything dissolved.
Since there are no instructions on the development time on the blog I decided to do a semi stand development similar to what I do with Caffenol. Agitate for the first 30 seconds then 3 inversions at 1, 2, 4, 8, 16 and 32 minutes. The total time was 70 minutes. I then did a water stop and fixed it normally. The negative came out very dark looking like it was over exposed and over developed. It's likely that I over developed it but I really don't think it was over exposed.
If anyone has any suggestions I may do another test today if I have time. I will definitely shorten the development time quite a bit.
With some digital manipulation this is the image I got. It is cropped a bit.
