Hi CH's, In a long and interesting post, George Nelson wrote: >Smell and taste the product during the fermentation (using a sanitary >technique). If tartness develops, this is good. Discard if there is >bitterness or "bitter white mold." There is another process by which sauces can be produced by salt tolerant yeasts. (Unfortunately I have forgotten the genus.) An example is Tabasco sauce. The yeasts appear as puffy white clumps reminiscent of popcorn. I have had such a mash working for about 18months and I will try it soon and report back on the results. I had an airlock fitted to the container but did not notice much gas evolution. Perhaps because the fermentation rate is so slow. --- Regards, Cameron.
