Novice Question from Papa Smirf

[Papa Smirf]

Several times throughout my reading of all grain mashing given to me several years ago I have seen a step after pitching the yeast .... "to avoid secondary firmentation and contamination add 1 gm of ammonium fluoride" I don't quite understand
..... ????

I think you can forget about that if you do a mash that will be distilled as you want all sugar to be fermented... it might apply for bear ore win making if you add more sugar when fermented out and do not want this sugar to be fermented...

I've never heard that in all the time I've been doing this.

Actually, in some mashes, what might be considered "contamination" can actually make a superior product. Many of the regulars here (myself included) swear by the fact that their stinkiest all grain mash made the best that they've ever had. There's even a thread about intentionally "contaminating" the wash, then adding the yeast later. http://homedistiller.org/forum/viewtopic.php?p=6710582

What could secondary fermentation mean?

[Dnderhead]

A fermentation after the "normal" yeast fermentation. in our case it genially cased by bacteria as malolactic (turns to vinegar)
in beer/wine after racking or bottling

[Dnderhead]

fermenting after the normal(yeast) fermentation , in our case means bacteria (and could turn to Vinegar)
in beer/wine means after racking /bottling to give carbonation.
