A very rare case of 1988 Romanée-Conti consigned from a private French collector is to be included in a Fine and Rare Wines auction on March 25, at Bonhams in London.

Wines from the Romanée Conti vineyard - the pinnacle of the Domaine de la Romanée-Conti in Burgundy - are considered among the very finest in the world, and it is exceptionally unusual to find a complete case of a dozen bottles.

This case, from the excellent 1988 vintage, was still sealed with its metal banding until opened for inspection by Bonhams. It is estimated to sell at £35,000-40,000.

A case of the excellent 1988 Romanée-Conti, estimated at £35k-40k

There is also a good assortment of 1989 wines from the Domaine from another Continental cellar, including bottles and magnums of La Tâche, as well as a case of Grands Echézeaux 1991 (estimated at £4,000-5,000) consigned from a private cellar in Scotland.

Highlights from a wide range of Bordeaux include magnums of Chateau Latour 1964 (£3,000-3,600 per six), a dozen Pétrus 1975 (£10,000-12,000) and six bottles of 1990 (£10,000-12,000).

A case of six magnums Chateau Haut-Brion 1985 (£2000-2600) and two dozen Chateau Lafite Rothschild 1986 (£9,000-11,000 per dozen) will also appear in the sale.

Elsewhere, a Domaine de la Romanée Conti 1999 assortment carries the highest estimate in this forthcoming Sotheby's fine wines sale, scheduled for March 17.

The assortment has a predicted value of £15,000-20,000.
