Is Whiskey Healthier Than Wine? What Science Says

Neither whiskey nor wine is truly “healthy,” but if you’re comparing the two, wine (specifically red wine) has a stronger association with cardiovascular benefits at moderate intake. A large study cited by the American College of Cardiology found that moderate wine drinkers had a 21% lower risk of dying from cardiovascular disease, while even low intake of spirits like whiskey was linked to a 9% higher risk. That said, the World Health Organization’s current position is that no amount of any alcoholic beverage is safe when cancer risk is factored in.

So the honest answer is more nuanced than a simple winner. Each drink has distinct trade-offs depending on what you care about: calories, blood sugar, hangovers, or long-term disease risk.

Calories and Sugar Per Serving

A standard 1.5-ounce pour of 80-proof whiskey contains about 97 calories. A 5-ounce glass of red wine comes in at roughly 125 calories, and white wine at about 128. If you’re drinking higher-proof whiskey (94 proof), that jumps to around 116 calories per shot, but it’s still lower than a glass of wine.

The calorie gap narrows quickly in real-world drinking, though. A 175ml glass of wine (slightly larger than the standard 5 oz) can reach 158 calories according to NHS data. And if you’re having two or three glasses over dinner, the total adds up fast. Whiskey’s smaller serving size makes it easier to keep calorie counts low, assuming you’re drinking it neat or with water rather than in a sugary cocktail.

Whiskey also contains zero sugar and zero carbohydrates. Distillation strips them out entirely. Wine keeps residual sugars from the grapes. A dry wine might have only 1 to 2 grams of carbohydrate per glass, but a sweeter wine can pack over 10 grams. For anyone watching carb intake or managing blood sugar, that’s a meaningful difference.

Blood Sugar Effects

Both whiskey and wine can cause unexpected drops in blood sugar because alcohol blocks the liver from releasing stored glucose. This effect can be delayed by several hours, which is why some people experience low blood sugar the morning after drinking. The risk exists with any alcoholic drink, but wine’s carbohydrate content creates a more complicated pattern: your blood sugar may spike initially from the sugars, then drop later as the alcohol takes effect.

Whiskey’s zero-carb profile means it won’t cause that initial rise, making the blood sugar response somewhat more predictable. This is particularly relevant for people with diabetes or insulin resistance, though alcohol’s overall impact on blood sugar regulation makes neither drink a safe choice in large quantities.

Heart Health: Wine Has the Edge

This is where the comparison tilts most clearly in wine’s favor. Red wine contains polyphenols, a class of antioxidant compounds that appear to protect the lining of blood vessels. Resveratrol, the most studied of these polyphenols, may help prevent blood clots, reduce inflammation, and lower LDL (“bad”) cholesterol. These compounds come from grape skins, which spend more time in contact with the juice during red wine production than white.

The cardiovascular data reflects this. The American College of Cardiology highlighted research showing moderate wine drinkers had a 21% lower risk of cardiovascular death compared to people who rarely or never drank. Spirits, including whiskey, told a different story: even low consumption was tied to a 9% higher risk of cardiovascular death. That’s a striking gap, and it suggests whatever protective compounds exist in wine aren’t replicated in distilled spirits.

Whiskey does contain trace antioxidants, particularly from aging in oak barrels. But the research base for whiskey-specific heart benefits is thin compared to the decades of data on red wine polyphenols.

Hangovers and Short-Term Effects

Both whiskey and red wine are high in congeners, the chemical byproducts of fermentation and aging that contribute to hangover severity. Darker drinks generally contain more congeners than lighter ones. Bourbon, for example, has been estimated to contain 37 times the congeners found in vodka.

Red wine is similarly congener-rich. So if you’re choosing between whiskey and red wine based on how you’ll feel the next morning, neither is doing you any favors. White wine, being lighter in color and lower in congeners, is typically easier on the body the next day. Clear spirits like vodka or gin are gentler still. If hangover avoidance is your priority, both whiskey and red wine rank near the bottom.

Cancer Risk Applies to Both

The WHO’s 2023 statement was blunt: the risk to your health starts from the first drop of any alcoholic beverage. This applies regardless of the type. The organization emphasized that no threshold exists below which alcohol’s cancer-promoting effects simply switch off. Even light and moderate drinking carries carcinogenic risk, and the WHO noted that the potential cardiovascular benefits of moderate drinking do not outweigh the cancer risk for individual drinkers.

Alcohol is a known carcinogen linked to cancers of the mouth, throat, esophagus, liver, colon, and breast. This risk scales with volume: the more you drink, the greater the danger. But the type of alcohol doesn’t change the fundamental equation. Ethanol itself, not the specific beverage, drives the cancer risk.

Which One to Choose

If you’re going to drink moderately and your main concern is heart health, the evidence favors red wine. Its polyphenol content and the cardiovascular data set it apart from spirits in a way that’s hard to dismiss.

If your concern is calories, carbohydrates, or blood sugar management, whiskey in small amounts has the advantage. A neat pour is one of the lowest-calorie, lowest-carb ways to consume alcohol.

If your concern is overall health and longevity, the most evidence-supported choice is drinking less of either one, or none at all. The benefits attributed to moderate wine drinking are real but modest, and they exist alongside a cancer risk that increases with every drink. For most people, the gap between whiskey and wine matters far less than the total amount consumed.
