Each batch, each vintage in the collection, is different. Grosperrin Cognac guarantees that:

For the batches and Trésors
  • it can provide evidence of the origin of every cognac and the minimum age if stated,
  • Grosperrin vintages and batches are free from additives (sugar/caramel/boisé),
  • for food safety reasons, the cognacs undergo gentle filtering at an ambient temperature at the time of bottling and are never chill-filtered,
  • each batch is bottled “cask by cask”,
  • the bottling date is stated on the warranty strip used to seal each bottle. Each bottle is numbered and traceable,
  • the Trésors and old cognacs are gravity extracted and bottled.
Our vintages

The same as for the batch cognacs and Trésors, plus we also guarantee that:

  • evidence of each vintage can be produced at any time,
  • all cask procedures are carried out in the presence of a judicial officer and a detailed report is drawn up,
  • a judicial officer is also present during bottling. The officer seals each bottle to certify that he or she has overseen the whole procedure.
