LETTERS PATENT to Henri Adrien Bonneville, of the British and Foreign
Patent Offices, 8, Rue de la Chaussée d'Antin, Paris, France, and 90 Cannon
Street in the city of London, Patent Agent, for an invention of A NEW
OR IMPROVED PROCESS OF TRANSFORMING TAFFIA AND RUM INTO COGNAC
AND FINE BRANDY."-A communication from Denise Cornilliac, wife of Adrien
Ralu, of Rue Condorcet, Paris, France.
COMPLETE SPECIFICATION filed by the said Henri Adrien Bonneville at the
Office of the Commissioners of Patents on the 22nd July 1882.
HENRI ADRIEN BONNEVILLE, of the British and Foreign Patent Offices, 8, Rue
de la Chaussée d'Antin, Paris, France, and 90 Cannon Street, in the city of
London, Patent Agent, A NEW OR IMPROVED PROCESS OF TRANSFORMING TAFFIA
AND RUM INTO COGNAC AND FINE BRANDY, A communication by Denise Cornilliac,
wife of Adrien Ralu, of Rue Condorcet, Paris, France.
The invention relates to augmenting the commercial value of, and increasing the
demand for, Taffia and Rum, and also to allowing the use of the juice of the sugar
cane directly in their manufacture, and consists in transforming the Taffia, the Rum,
and the phlegms or alcoholic juices of Taffia and Rum, into Cognac and Fine wine
Brandy by the processes to be here described, of reduction of their degree of alcoholic
strength, or by simple maceration, or by distillation.
TREATMENT BY REDUCTION OF DEGREE OF ALCOHOLIC STRENGTH.
Taffias or Rums of about 60 degrees strength by Gay-Lussac's centesimal
alcoometer are taken and reduced to about 45 or 50 degrees strength by the same
instrument; this is effected by means of the juice of Pine Apple or Cashew Apple,
or any other juice containing a mordant or dissolvent capable of acting upon and
influencing the alcoholic bouquet so as to make it easy afterwards to modify them
completely by incorporating into them an essence or an ether.
When Taffia or Rum is to be reduced to 45 degrees strength, raw Pine apple or
Cashew apple juice is used.
When, on the other hand, they are to be reduced to 50 degrees strength, juice
concentrated over the fire in copper pans is, used. As soon as the juice, (which
has been carefully skimmed) boils, it is poured out of the pan and left to cool,
after which it is mixed with the Taffia or Rum until the desired strength is
obtained.

page_text: Any kind of rectifying apparatus may be used, or in particular, that of either
Egrot or Druon which clear the phlegms of their essential oils and ethers most
effectually.
With Egrot's apparatus for instance, nothing is more simple, the Taffia or Rum
of about 45 or 50 degrees strength by Gay Lussac's centesimal alcoometer is heated
in the boiler of the apparatus and cleared of the alcoholic vapours which arise in
the washing plates in the upper column of the apparatus, and pass by a swan neck
into the rectifying worm.
The first water which forms there will run back into
the said column by two tubes. The vapors again enter by a swan neck into the
refrigerating worm in which they are condensed, the product flows to the gauge
placed at the exit of the refrigerating worm.
The refrigerating water descends from a tank placed above the apparatus, and
runs out by an overflow contrived for the purpose.
When the operation is finished, the plates of the column on the top of the boiler
are washed by allowing the water to flow from a special tap.
The Taffias or Rums resulting, exceed 90 degrees strength by Gay-Lussac's
centesimal alcoometer and are perfectly neuter; they only require then to be reduced
to 45 or 50 degrees by the same instrument and to have the ether or proper bouquet
incorporated, and they are transformed.
Having thus described the said invention and the manner in which the same is
to be performed, I claim and desire to secure by the said Royal Letters Patent :
1st the transformation of Taffia and Rum into Cognac and Fine Brandy, either by
reducing their degree of alcoholic strength, or, by maceration, and the incorporation
of essence or ether of Cognac substantially as above described.
2nd The transformation of Taftia and Rum and also phlegms and alcoholic juices,
into Cognac and Fine Brandy by distillation and the incorporation of an essence or
ether of cognac substantially as above described.
In witness whereof, I, the said Henri Adrien Bonneville, have hereunto set my
hand and seal, this twenty first day of July in the year of our Lord One
thousand eight hundred and eighty two.
