Danbo,
I vac bag 90% of my cheese, as long as they are dry, I've had no problems----every once in awhile the vaced bag puts enough pressure on the cheese to expel some whey, I just keep an eye on them for awhile, and if it does happen, I just take it out and dry and repack---I used to wax most of them----but I think I like the vac bag better because I can see what's happening and it doesn't seem to change the aging.
