A very fine DSOT cordial glass having a rare twist formation combining a solid corkscrew with a 15 ply tape, all on a "helmet" domed foot. Helmet dome cordials are considered by many to be of Irish origin - though it has to be said there is no written evidence for this.

For an excellent essay on both cordial/strong waters and the glasses used I can thoroughly recommend "...Strength and Chearfulness" published by Delomosne & Son Ltd, 1997.
