I have come across some more interesting information about the condiment called Taste #5 Umami and it has to do with the ingredients and where to purchase. For those of you the Cambridge, MA area, the choice is easy as it can be found at Cardullos, 6 Brattle Street, Cambridge, MA 02138. It is available from them online.

Also, here are the ingredients, which Do Not include MSG.
