Most 17th-century wine bottles are inscribed with the type of the wine and a date followed by a flourish. According to Michael Archer, Delftware, The Tin-glazed Earthenware of the British Isles, London, 1997, p. 266, 'Claret' had assumed the meaning of any type of wine by 1600, although most of the consumption in England at the time came from Bordeaux. Archer illustrates a similar wine bottle of the same date, ibid., cat. no. E8, p. 270, where he quotes its previous owner in the 19th century, Lady Charlotte Schreiber: '..first to Aked's where I had the great good fortune to find one of the Lambeth Wine bottles marked "Claret". I already possessed the "Whit-Wine" and "Sack" - so this makes my set complete." It is interesting to note the transition of the wine bottles from being used as functional objects in the 17th century to having a rather more decorative purpose as expressed in Lady Schreiber's need to complete her "set."
