Tetrahydro iso-&#x3b1;-acids and hexahydro iso-&#x3b1;-acids are prepared from &#x3b2;-acid resins in the presence of &#x3b1;-acids derivatives without the use of conventional organic solvents. Specifically, the hydrogenation and hydrogenolyzis step is performed using a liquefied hop resin composed of &#x3b2;-acids and &#x3b1;-acid derivatives, hydrogen, and a noble metal hydrogenation catalyst to form desoxytetrahydro &#x3b1;-acids and hydrogenated iso-&#x3b1;-acid derivatives (e. g., tetrahydroiso- and hexahydro iso-&#x3b1;-acids). The desoxytetrahydro &#x3b1;-acids are subsequently auto-oxidized and isomerized by the spent noble metal catalyst in an aqueous alkaline solution (without adding peracids, lead, calcium, or magnesium salts) into the desired tetrahydro iso-&#x3b1;-acids and hexahydro iso-&#x3b1;-acids.
