Gaston de Casteljac, brand owned by Bordeneuve Chateaux & Collections in Castelnau d’Auzan
The Bordeneuve Chateaux & Collections company is owned by the Guasch family. They are primarily known for their Armagnac: Baron de Sigognac. Father Jean-Claude and son Thomas run this centuries-old family business.
In 2010 the old name Adex was changed to Bordeneuve Chateaux & Collections and a new website was also set up. Sadly, you won’t find much about their cognacs on this new website.
Range: (from 1965 they are all grande champagne cognacs, before that they were fine champagnes): VS, VSOP, XO and quite a few vintage wines.
