FRMNTThe Sourced Fermentation Knowledge Platform
Fermentation knowledge is scattered across academic papers, family kitchens and forum threads that contradict each other. FRMNT is an attempt to hold it in one structured place: variants, ingredients, microorganisms, methods, safety thresholds and outcomes, each connected and each traceable.
Every entry records how well documented it is, and every safety statement carries that confidence with it. Where the literature disagrees, we say so instead of picking a convenient answer; where nothing has been established, the entry says that too rather than offering a plausible number.
Each variant carries a confidence score reflecting how well documented it is. A well-studied ferment like sauerkraut and a rare regional preserve are not presented as equally certain.
Ferments are documented with their local names and countries of origin. The world map is the entry point, not an afterthought.
Community posts come from logged batches with dates, observations and outcomes. That is what makes the success rates on our pages meaningful.
FRMNT publishes food-safety information, not medical advice. We use conservative thresholds — notably pH 4.6 for acidified foods — and we say discard where the evidence is unclear. If a batch shows fuzzy coloured mould, an off odour that is putrid rather than sour, or fails to acidify, the guidance is always the same: discard it.
