As a rule of thumb, the darker the drink, the stronger the effect. So, red wine and darker spirits, like whiskey, tequila or brandy, tend to hit you faster. This is thought to be because dark spirits contain more congeners, a by-product of distilling. Hangovers tend to be less intense when drinking white wine, beer or clear spirits like vodka or gin. But, drinking in moderation is the real key. Too much of any of these will give you that morning-after feeling no matter what.
