Maturing process

The secret Asbach maturing
and finishing process

The art of the cellarers.

When the distillation process has been completed, the fresh wine distillates are transported to Ottersweier at the foot of the Black Forest. This is the site of the Asbach maturing cellar, unique among its kind and in its size, as well as the Asbach Treasure Trove.

The duration of the maturing process is the next step that is decisive for the high quality of the Asbach brandies. Here at Asbach, we leave the distillates in the small Limousin oak casks far longer than required by law until they have reached their full maturity and developed their characteristic bouquet.

The maturing process takes place in small oak casks made of wood from the Limousin oak that has been aged for a number of years. This wood has especially large pores and is air-permeable so that the fine spirit can breathe and mature in an exchange process with air.

“The fine spirit draws the natural aroma and colour substances from the cask, and this is where the liquid, originally clear, gains its topaz colouring and subtle, harmonious wooden accents.

The part of the distillate that escapes, on the other hand, is lost; it fills the air in our cellars with an aromatic fragrance, which has led us to call it the angels’ share.”

The distillates, even of one type, never mature perfectly evenly within the distillate cellar because the wine distillate and the wood are both natural products that react differently from one cask to the next. The various distillates do not reach their full maturity and perfect harmony until the second maturing process in large vats made of Spessart oak.

The result

Ultimately, however, it is the art of the master distiller that creates the masterpiece from various distillates of different origins and vintages.

The secret Asbach maturing and finishing process brings the complex production process to a close and gives Asbach its radiant topaz hue, harmoniously blended with the full aroma of wine and its characteristic bouquet.

Creation of a masterpiece

The cooperage

Asbach is the only distillery in Germany that even today employs its own cooper. Our cooper, one of the last of his profession in Germany, devotes his work primarily to the repair and care of the Limousin oak casks and of the large vats made of Spessart oak.

The casks are crafted from the valuable wood of the Limousin oak that is stored in the open air for a number of years. They are put together over an open fire without the use of glue or nails.

Heat and water make the wood pliable. The cooper delivers powerful hammer blows to drive the rings onto the casks. Finally, the cooper brands the cask number and the Asbach lettering on the cask.
