From what I remember, I do dry the cheese on a bamboo mat, everything was cleaned with bleach before hand. I do remember even though the cheese had somewhat yellowed, dry corners, the very top and bottom were slightly damp to the touch. During aging, it was leaking for about a week, the first one i made leaked for around 4 days but stopped and was fine, so i thought this time it was still normal. From what I have learned, leaking isn't the best thing in the world
I pressed the cheese as directed at exactly 15 pounds, i remember the first one i used a 1 gallon bucket of rocks and i'm sure it was more than 15 pounds.. But doing as directed in the leeners book, doesn't seem to be enough.
I'm not sure what gas is suppose to smell like.. it is odd and because there's no way of telling how bad the problem is, i'm assuming there's no saving it.
