點解飲紅酒比白酒易醉?

red wine is drank at room temperature. so when it reaches the stomach the alcohol in the wine is easily absorbed by the blood-capillaries in the stomach lining. therefore alcohol gets into the bloodstream faster.
white wine is usually drank cold. when cold liquid reaches your stomach the blood-capillaries in the stomach lining contracts because of the cold temperature (called "vasoconstriction"). therefore absorption of alcohol is slower.

baby兄, 事實係咁喎! 飲凍嘢個胃內血管會收縮 (vasoconstriction), 減慢酒精吸收. 所以同樣係四十幾%酒精, 飲大麯 (通常熱飲) 會快醉過伏特加(通常凍飲).
