To establish the optimal conditions for increasing oil yields from grape seed, extraction solvent, extraction time, and temperature were examined. Using grinding, grinding and roasting, grinding and steaming, and grinding, roasting, and steaming methods. Pressing extraction method resulted in 34.0% oil yield. Grinding and roasting, grinding and steaming, and grinding, roasting, and steaming gave 64.3, 63.0, and 65.6% yield, respectively. Ether solvent treatment resulted in 77.4 and 80.9% recoveries after 24 and 48 h static, respectively. The results of sensory evaluation revealed, oils extracted under optimal condition showed the best flavor, aroma, and whor, followed by grinding, grinding and roasting, grinding, roasting, and steaming, and grinding and steaming. Taking these results together, the optimal methods for oils extraction from grape seed were as follows: grape seed ${
ightarrow}$ washing ${
ightarrow}$ drying ${
ightarrow}$ roasting ($95{sim}100^{circ}C$ for 20 min) ${
ightarrow}$ cooling (room temperature) grinding ${
ightarrow}$ (0.5 mm>) ${
ightarrow}$ steaming ($0.8{sim}0.9;kg{cdot}f/cm^2$ for 10 min) ${
ightarrow}$ pressing ($1st;400;kg/cm^2;for;2{sim}3;min,;2^{nd};550{sim}600;/cm^2$ for 10 min, $3^{rd};700kg/cm^2$ for 60 min) ${
ightarrow}$ oils (yield $;85{sim}90%$).
