Do certain types of alcohol beverages have more methanol than others?
Yes. There appears to be a relationship between the likelihood of getting a hangover and how dark the alcohol is. The color means that the alcohol has more junk in it. The darker color is somehow reflecting the level of congeners. So more clear-colored alcohols, like vodka and gin, are less likely to give you a hangover than a darker-colored alcohol, like a whiskey or a scotch, bourbon or brandy. Likewise, among wines, people often find they’re more likely to get a headache from red wine rather than white wine. Sulfites in red wine may contribute to hangover in people who are sensitive to them.
