Abstract
A fusel oil is an alcohol or a mixture of alcohols having more than two, typically four or more, carbon atoms, whose presence in alcoholic solutions may be undesirable on account of its characteristic effect on taste and/or aroma. By reducing the temperature of alcoholic aqueous media containing fusel oil, the solubility of the fusel oil in the solution may be reduced, to the point where it no longer remains in solution. The fusel oil being lighter than aqueous alcohol, the medium separates into two phases, and the fusel oil phase may be removed. A better separation of fusel oil from the alcoholic aqueous phase is thus obtained than is possible through conventional dilution processes.
Claims (15)
1. A freeze distilled alcohol.
2. A freeze distilled alcoholic beverage comprising freeze distilled alcohol according to claim 1.
3. Freeze distilled vodka.
4. A process for removing fusel oil from an aqueous alcoholic medium, comprising the steps of:
(a) cooling the medium to effect separation of fusel oil from the medium; and (b) removing at least part of the fusel oil from the medium.
(a) cooling the medium to effect separation of fusel oil from the medium; and (b) removing at least part of the fusel oil from the medium.
5. A freeze distillation process for preparing a freeze distilled alcohol, the process comprising partial or complete removal of fusel oil by the steps of:
(a) removing an alcoholic aqueous fraction comprising ethanol and fusel oil from the distillation;
(b) cooling the fraction to reduce the solubility of the fusel oil therein;
and (c) separating the aqueous fraction from the fusel oil, and returning the thus separated aqueous fraction to the distillation.
(a) removing an alcoholic aqueous fraction comprising ethanol and fusel oil from the distillation;
(b) cooling the fraction to reduce the solubility of the fusel oil therein;
and (c) separating the aqueous fraction from the fusel oil, and returning the thus separated aqueous fraction to the distillation.
6. A process according to claim 5, wherein the distillation process comprises a single distillation step.
7. A process according to any one of claims 4 to 6, wherein the alcoholic aqueous fraction comprises between 20% and 30 % ethanol.
8. A process according to any one of claims 4 to 7, wherein the alcoholic aqueous fraction is taken from the distillation column at a temperature of between 80 and 95°C.
9. A process according to any one of claims 4 to 8, wherein the alcoholic aqueous fraction is cooled to below 0°C.
10. A process according to claim 9, wherein the alcoholic aqueous fraction is cooled to between -5°C and -15°C.
11. A process according to claim any one of claims 5 to 10, wherein the fusel oil is rendered substantially insoluble in the alcoholic aqueous fraction by cooling.
12. A process according to any one of claims 4 to 11, wherein the alcohol has a final concentration of at least 96 % v/ v.
13. A process according to any one of claims 3 to 12, wherein the alcohol is employed in the production of an alcoholic beverage.
14. An apparatus for distilling an alcohol, comprising a distillation column, a withdrawing system for removing a fraction from the distillation apparatus, at least one heat exchanger or cooler, a separation vat and a replacing system reintroducing for material from the separation vat to the distillation column, wherein, in use, an alcoholic aqueous fraction comprising ethanol and fusel oil is taken from the distillation apparatus via the withdrawing system, cooled in the heat exchanger or cooler to a point such that the fusel oil becomes substantially insoluble in the alcoholic aqueous fraction, the fusel oil is separated from the alcoholic aqueous solution in the separation vat and the alcoholic aqueous fraction is returned to the distillation column via the replacing system.
15. A distillation apparatus as hereinbefore described, with reference to the drawings.
