Methanol slicing of wine
View Patent ↗A method and apparatus are presented for reducing the methanol content in a fermented solution to create forms healthier to human consumption, thereby reducing headaches and hangovers. In accordance with the disclosed embodiments, the fermented solution is placed in a vacuum vessel and heated to a fixed temperature. Pulling a fixed vacuum within the vessel lowers the boiling point of the solution, creating a vapor selectively of the low-end congeners, for example, methanol. The methanol-rich vapor is condensed and disposed leaving a healthier fermented solution with reduced methanol content. In some embodiments, the fixed temperature is lower than or equal to 32 degrees C. which preserves the aroma and taste of the fermented solution.
1. A method for reducing methanol content in a fermented solution, comprising:
a. heating a fermented solution in a vacuum vessel to a fixed temperature, the fermented solution occupying a portion of the volume of the vessel;
b. lowering a boiling point of the solution by pulling a vacuum within the vessel to create a vapor; and
c. extracting the vapor, thereby producing a reduced methanol fermented solution without substantially reducing ethanol content.
2. The method of claim 1 , wherein the fermented solution is heated to a fixed temperature of 32 degrees Celsius or less.
3. The method of claim 1 , wherein the fermented solution boiling point is lowered to 32 degrees Celsius or less.
4. The method of claim 1 , wherein extracting the vapor is performed using a condenser.
5. The method of claim 1 , wherein extracting the vapor is performed for less than 60 minutes for 23 liters of solution.
6. The method of claim 2 , wherein the fermented solution is heated using one of a water bath and a submersible heating coil.
7. The method of claim 1 , wherein the resulting condensate is monitored for generation of methanol.
8. The method of claim 2 , wherein the fermented solution temperature is monitored for generation of methanol.
9. The method of claim 1 , wherein the reduced methanol fermented solution is returned to room temperature and pressure when the generation of methanol substantially ceases.
10. The method of claim 1 , wherein said fermented solution is wine.
11. The method of claim 1 , wherein said fermented solution is beer.
12. The method of claim 1 , wherein Meta is added to the fermented solution prior to heating to compensate for SO 2 loss during the methanol reduction.
