Okay, so I know this is a little nutty, but has any one here ever tried to preform a Supercrticical-CO2 extraction with hops? This is the technique where CO2 under high pressure and in its supercritical liquid state is used as a solvent to extract organic materials, in this case the oils and acids in the hop flower.
In an industrial setting CO2 is is pumped through a column of hops at between 5-10ºC at a pressure of 60bar for the low pressure method. Higher pressures and temps can be used for a more efficient extraction but we are already at 870psi with the current industrial method.
The Idea I have is if you have hops in a small chamber, and pressurize that chamber to 100psi, and chill it to -30ºC the CO2 will be in a liquid state (not supercritical ) and should act as a solvent.
Just a nutty idea any one ever try it?
