Mr. Kelt was a well-honed historian. As his family hails from Scandinavia, he was very familiar with the Norwegian aquavit which has its maturation at sea. The maturation process includes: transported in aged oak casks from Norway to the Equator and then back again. The idea began to form that this was a method which should be tried to see if it works. The idea was to recreate a quality given by the sea, this could be beneficial and a further step on the road to perfection. With assistance from special container, the decision was that the best way to effectuate the sea voyage would be to let the container stay on a ship that did a continuous world round-trip taking 90-110 days depending on weather.
Further trials were made to optimize the effects. Smaller barrels proved to be most efficient. Traditional oak barrels are used which must be extensively research. The barrels must only be filled to 70% capacity so that there is ample room for the cognac to wash around inside the barrel which facilitates contact and extraction from the wood as well as exchange of oxygen.
The process takes an easterly direction. It has been experienced that there is a considerable difference between going east or west. For some unexplained reason a westbound, does not produce as good an effect as going eastbound. After leaving France, the direction takes cognac to a few Northern European ports, then heads south into the Mediterranean, through the Suez canal into the Arabian Sea and from there on to Sri Lanka, Singapore, Hong Kong, Taiwan, Korea, Japan and across the Pacific to the United States and Los Angeles. From Los Angeles we turn south for the Panama Canal and then north again following the east coast of the US to New York before the return across the Atlantic Ocean back to France. After returning, the cognacs are allowed a period of rest before bottling. This period varies between 3-5months.
All of the above takes place to make the best cognacs in the world and it is natural to find perfection through studying history and traditional methods rather than looking to the future and technology.
