Hennessy Master Blend Selection Nº4 is the fourth cognac released by Hennessy in its Master Blender’s series. The series was created to highlight the skill of the master blender. Hennessy’s former master blender and cellar master Yann Filloux initiated the series with Hennessy Master Blend Selection Nº1. The Master Blender’s selection was designed to produce single batch Cognacs that not only display the skill of the master blender but also showcase the rich and varied eaux-de-vie on hand at Hennessy.
