TSG
Also written Traditional Speciality Guaranteed. Each is a name for the same thing, which is why none of them has an entry of its own.
Definition
A protected name for a traditional recipe or method rather than a place. A TSG can be made anywhere, provided the specified traditional composition or production method is followed.

The register itself is an index; the substance is in the product specification attached to each entry as a PDF. Eight cider and perry specifications were downloaded and read on 2026-08-24 — the six Three Counties names and the two Welsh ones. Reading them settled a question CiderHQ had previously described in the abstract and got wrong: the Three Counties specifications state a composition table, not a minimum juice content. The Traditional Welsh Perry specification was re-read on 2026-08-25 for the comparison with Austrian fruit-wine law, and its prohibition list transcribed in full: the two instruments turn out to regulate opposite things, one composition and one technique.
