For several years, "order clear" has seemed to be shorthand for a "healthier" choice at the bar. Vodka sodas, tequila with lime, gin and tonics, they’ve all been positioned as cleaner, lighter, and somehow better for you than whiskey, rum, or other darker pours. But when you look at the science, that argument starts to fall apart.
The color of your drink isn’t doing nearly as much work as you may think.
"From a nutrition and metabolism standpoint, the color of alcohol is not the key variable," says registered dietitian Anya Argosh, MS, RD, IFNCP. "The dosage of alcohol, the drinking patterns, and what the drink is mixed with matter far more than whether the spirit is clear or dark."
What and how you drink matters more than the color of the alcohol.
"Paying attention to total alcohol intake and gradually reducing consumption has a much greater impact on health than worrying about whether a spirit is dark or light," says registered dietitian Roxana Ehsani, MS, RD, CSSD, LDN.
That being said, some people report feeling worse after drinking darker drinks. So, what’s the deal?
One of the main reasons that some hold darker spirits in question are compounds called congeners.
Registered dietitian Ashley Berthoumieux, MS, RD, CDN, LDN, says that "congeners, which are byproducts of alcohol fermentation, have been identified as potential contributors to hangovers and can be measured in the blood."
So, there’s some truth that darker spirits might make you feel worse the next day. Research has shown that drinks higher in congeners, like bourbon, can result in more severe hangovers than options with very few congeners, like vodka.
But congeners aren’t the main problem.
"Ethanol, the intoxicating component of all alcoholic beverages, has a significantly greater impact on hangover severity than the congener content," says Berthoumieux.
Darker liquors may contribute to worse hangovers for some people, but that doesn’t mean they’re more harmful overall.
"It’s largely about quantity and drinking patterns," says Argosh. "Factors such as how much you drink, how quickly you drink, sleep quality, hydration, and added sugar in mixers all play a much larger role in how alcohol affects the body."
Berthoumieux says that "the severity of these effects is highly individual, so pay attention to how drinking affects you personally." If whiskey consistently leaves you feeling awful while vodka doesn’t, that’s useful data for you. But it’s not necessarily universal.
Another persistent myth is that clear spirits are lower in calories. Most standard pours are nearly identical.
"All spirits contain calories, specifically 7 calories per gram of alcohol, regardless of whether they're dark or clear," says Berthoumieux.
Ehsani puts it simply: "Whether you're picking a clear liquid such as vodka, or [a] darker one like rum, both will be about the same amount of calories. For example, a 1.5-ounce shot will be around 100 calories."
Where the difference is in what’s added to the drink. Flavored spirits, liqueurs, and sugary mixers can change the nutritional profile.
"Those with added flavors or spices, such as liqueurs, flavored whiskies or vodkas, spiced rums, etc., tend to have the most sugar and, as a result, the most calories," says Berthoumieux.
Argosh says that "the proof of the alcohol and what it’s mixed with determine calorie and sugar content much more than whether the spirit is clear or dark."
So, a vodka soda and a whiskey ginger aren’t vastly different from a nutritional standpoint because one is clear and the other is dark. They’re different because of what else is in the glass.
