Title: Ammonia in Blue cheese.
Post by: T-Bird on December 18, 2013, 12:11:07 AM
Just opened a 2 gal blue that I caved at 50 deg. Oct 22. I pierced on Nov.22 and cut today. Internal blue was VERY good Looks just like the last one that I posted here last year. It has a faint odor and taste of ammonia. Last years cheese did too. No one complains about it but me. I cut this one a week earlier that last years to try to alleviate the taste. I have read that most of the ammonia  taste can come from the rind from dying mold etc. The cheese was never overly moist, never got too warm, etc. I let it sit on a bamboo mat that was sterilized before this cheese. covered with a plastic hood turned daily and in a small wine type fridge that I can set the temp on. I set it and checked it for 3 days before putting the cheese in. My first blue I made (several years ago now) I scraped the rind about once a week as it aged  as per a recipe I used then. Should I go back to scraping the rind? My cheese didnot blue nearly as well internally with the other recipe and method but that once I had no ammonia taste.

I find airing the cheeses for 45 minutes or so each day helps them to mature without ammonia buildup.

Most of the time on my blues I have a slight ammonia aroma (http://cheeseforum.org/forum/index.php/topic,9152.0.html) when I bring the cheese out for it's daily walk (airing) more dirty feet than anything.
and I air it for 30 to 60 minutes a day, I haven't had one that was so bad with ammonia that it stayed in the cheese after cutting or infected the taste (knock on wood).
I did have a problem when I was using  bamboo mats, that was a long time ago.

I haven't aired my cheeses because I thought they could breathe thru the mat. I did age the 1st cheese in a plastic bag, I did air it. I have cut the pieces now. Will unwrapping and airing do any good now? The taste is not strong. My wife doesn't notice. She says it is "just the cheese"

Airing now will help your cheeses. The ammonia smell doesn't always affect the cheese. We tried a stilton-type that had been closed a little too long last night, and which I thought smelled quite ammoniated. The flavour was a very subtle stilton, with no trace of ammonia at all.

Ok, I''ll open all the little packs and let them air. The cheese LOOKS wonderful. But I can't stand the "off" taste.Now that I've gotten the internal bluing thing down, I may have to alter my aging techniques. This learning curve for cheese is quite gradual. Guess I should make more than 1 a year for a while. Thanks for the help.

Absolutely, air them for awhile. my first one had a very strong ammonia smell, I thought I had another fail, I started to air it twice a day and after 4 or 5 day's it was all but gone.
when we cut it, it turned out wonderful :)

would it be effective to air them after refrigerating them? My only choice now is to take them in and out of the fridge- which I can do.

for future reference, this ammonia thing is usually related to lack of air circulation?

That's my understanding. Without air circulation, the natural ammonia gas has a chance to build up. It's fine to take them in and out of the fridge, that's what I do.
