Abstract
New stable, concentrated aqueous solutions of tetrahydro iso-alpha acid (THIA) and hexahydro iso-alpha acid (HHIA) are disclosed. These solutions depend upon the presence of a second kind of iso-alpha acid to increase the solubility of both iso-alpha acids to a point outside of the ranges of their normal solubilities . . . in the case of THIA and HHIA, to a point above their solubility ranges and, in the case of unreduced iso-alpha acid (UIA) and dihydro iso-alpha acid (DHIA), to a point below their commercial prior-art solubility ranges. This 'inversion' of solubility and stability behavior in water, which requires the presence of two different kinds of iso-alpha acids, is new to the art, and provides a novel approach for making commercially-desirable concentrates of THIA and HHIA available to the brewer.
