The Extreme expression sits at the very top of the Tesseron Cognac range, made with eaux-de-vie from the Grande Champagne region using Ugni Blanc, Folles Blanche and Colombard grapes. The spirits are allowed to age Tesseron's twelfth-century cellars before blending, and this particular expression has been made using some of the House's oldest stocks. It comes presented in a 1.75 litre bottles alongside a rather shiny case.
