Related terms
Terms that belong to the same part of the subject, or that this one is routinely confused with.
Equipment
Cask
A wooden vessel of staves bound by hoops, bulging at the middle so it can be rolled and turned. Casks both store cider and shape it, admitting a slow ingress of oxygen through the wood.
Equipment
Bag-in-box
A collapsible plastic bag inside a cardboard carton, fitted with a tap. Because the bag collapses as the cider is drawn, no air enters, which makes it a good format for still, unpasteurised cider.
Cider
Draught cider
Cider dispensed from a cask, keg or box rather than from a bottle or can. In British usage it also implies a serving format eligible for the reduced draught rate of alcohol duty.
Law and labelling
Draught relief
A reduced United Kingdom duty rate for qualifying products packaged in large containers for dispense on licensed premises, intended to favour on-trade draught sales over packaged retail.
Fermentation
Forced carbonation
Dissolving carbon dioxide into finished cider under pressure, in tank or in line, rather than generating it by fermentation.

Campaign for Real Ale · specialist organisation · retrieved 2026-08-24
Opened on 2026-08-24. Registered for the consumer-campaigning vocabulary — "real cider", "full juice" — which is advocacy language rather than legal definition, and is recorded as such wherever CiderHQ uses it.
Cider and perry production technical training material
Peter Mitchell / Cider and Perry Academy · reference work · registered as competent for this subject
Searched again on 2026-08-25 and it remains the one printed source here that a bibliographic check cannot fix, because it is not a published work with an edition. It is course material issued to participants of a training programme, so there is no catalogue record to verify, no ISBN, and no lawful public copy. Its state stays `registered` for that reason rather than through inattention.
