Related terms
Terms that belong to the same part of the subject, or that this one is routinely confused with.
Fermentation
Inoculation
Adding a selected yeast culture to the juice to conduct the fermentation, usually after rehydrating dried yeast or building a starter.
Fermentation
Pied de cuve
A starter made from the must itself: a small parcel of juice allowed to begin fermenting spontaneously, then added to the main tank to give the native population a head start.
Microbiology
Yeast
A single-celled fungus that ferments sugar to ethanol and carbon dioxide. Cider is fermented by a succession of yeast species, of which *Saccharomyces cerevisiae* usually finishes the job.
Fermentation
Stuck fermentation
A fermentation that has halted before the sugar is used up and will not restart on its own. It is distinct from a deliberately arrested ferment and from a merely sluggish one.

That establishes the citation points at a real book in a stated edition, which is what a citation needs and is all it establishes. No copy was opened and nothing is quoted from it. The book itself is in print and not digitised in any open collection; where CiderHQ needs a figure from this territory it uses an accessible research source instead and says so.
