Glutamic acid is an amino acid.  MSG (monosodium glutamate) is a sodium salt of glutamic acid.  I believe that the addition of calcium sulfate is effective to reduce soy salt flavor because the calcium binds the glutamate/glutamic acid.

Nice to hear some chemistry of this vector.  I make additions of calcium sulfate to my water
when I adjust the water chemistry for brewing.....fingers crossed I never get those flavors.

I believe that I know when to retire the solera.  I put the wine thief in thru the pellicle and
pulled out a small sample.  The taste was overwhelming acetic acid vinegar.  I guess technically
I could use the cask to produce more vinegar but, I do not believe that is the direction I
wish to persue......The liquid looks good and smells great...taste is vinegar....cherry vinegar.

R.I.P.

May be it'll become a nice planter in the yard   ;D

You could always empty it and scorch it with 180+ water to kill any sort of bug activity. Here's a good article (http://morebeer.com/public/pdf/wbarrel.pdf) to look at too. It depends whether you want to invest the time and effort in the hopes of further barrel sours!
