Any drink containing ethanol (alcohol) can make you drunk. That includes beer, wine, spirits, cocktails, hard seltzers, and fermented drinks like mead or sake. What changes between them is how much alcohol each one delivers per sip, how fast your body absorbs it, and what you mix it with. A standard drink in the United States contains 14 grams of pure alcohol, whether that comes from a 12-ounce beer, a 5-ounce glass of wine, or a 1.5-ounce shot of liquor.
Alcohol Content Across Drink Types
The single biggest factor in how drunk a drink makes you is its alcohol by volume, or ABV. Beer typically ranges from 5% to over 10% ABV. Wine averages 11% to 13%. Distilled spirits like vodka, rum, gin, tequila, and whiskey sit around 40% ABV (80 proof). Proof is simply double the ABV number, so a 100-proof bourbon is 50% alcohol.
This means a shot of vodka packs roughly eight times the alcohol concentration of a typical beer, ounce for ounce. But because you drink far less of it per serving, a single shot and a single beer deliver roughly the same amount of pure alcohol. The concept of a “standard drink” exists precisely because of this: 12 ounces of 5% beer, 5 ounces of 12% wine, and 1.5 ounces of 40% spirits all contain about the same 14 grams of ethanol. Drink for drink, they’re equivalent.
Where people get tripped up is with drinks that don’t fit neatly into these categories. A craft IPA at 8% or 9% ABV in a 16-ounce pint glass contains nearly twice the alcohol of a standard beer. A generous restaurant pour of wine can easily be 7 or 8 ounces instead of 5. A Long Island iced tea contains multiple shots of different spirits in a single glass. These drinks deliver more alcohol per serving than you might expect, which is how people end up drunker than planned.
Why Some Drinks Hit Faster
Not all drinks reach your bloodstream at the same speed. Alcohol is absorbed slowly from the stomach but rapidly from the small intestine, so anything that moves alcohol out of your stomach faster will make you feel its effects sooner.
Spirits get there quickest. Research comparing beer, wine, and vodka tonic found that blood alcohol peaked about 36 minutes after drinking vodka tonic, compared to 54 minutes for wine and 62 minutes for beer. That’s a meaningful gap. The likely reason: beer and wine have more volume and more non-alcohol content (carbohydrates, proteins, polyphenols) that slow stomach emptying. A concentrated shot or a spirit-based cocktail passes through the stomach faster, sending alcohol to the small intestine where absorption is rapid.
Carbonation also plays a role. In a study of 21 participants, two-thirds absorbed alcohol faster when it was mixed with a carbonated beverage compared to a still one. The carbonation appears to speed up gastric emptying. This means sparkling wine, champagne, gin and tonics, and rum and colas may produce a faster buzz than their flat equivalents.
Diet Mixers Increase Intoxication
If you mix spirits with diet soda instead of regular soda, you’ll likely reach a higher peak blood alcohol level. The sugar in regular mixers slows stomach emptying, which slows absorption. Without that sugar, alcohol passes into the small intestine faster. Studies have consistently shown that diet mixers lead to greater intoxication than regular mixers, with higher breath alcohol readings and increased risk of exceeding the legal driving limit of 0.08% BAC. The difference is enough that someone who feels fine after two rum-and-Cokes might feel noticeably more impaired after two rum-and-Diet-Cokes.
Food, Body Size, and Timing
The same drink can produce very different levels of intoxication depending on the circumstances. Eating before or while you drink slows gastric emptying significantly, which delays absorption and lowers your peak blood alcohol. A meal rich in fat and protein is especially effective at this. Drinking on an empty stomach does the opposite: alcohol moves quickly to the small intestine, and you feel the effects within minutes.
Body weight and composition matter because alcohol distributes through body water. A smaller person has less water volume to dilute the alcohol, so the same drink produces a higher blood alcohol concentration. Body fat percentage plays in too, since fat tissue contains less water than muscle. Two people who weigh the same but carry different amounts of body fat will reach different BAC levels from the same number of drinks.
Your liver clears alcohol at a relatively fixed rate: roughly 0.015 to 0.020 BAC per hour. That means if you’re at the legal limit of 0.08, it takes about four to five hours to return to zero. Drinking faster than your liver can process is what causes BAC to climb. This is why shots, drinking games, and rounds of drinks produce intoxication so quickly: they front-load alcohol faster than your body can handle it.
Dark Versus Light Liquors
You may have heard that dark liquors like bourbon, brandy, and red wine make you feel worse than clear spirits like vodka. There’s some truth to this, but it’s mostly about the morning after rather than the night of. Dark-colored spirits contain higher levels of congeners, which are byproducts of fermentation and aging. Bourbon has among the highest congener levels, while vodka has essentially none.
Research confirms that bourbon produces more severe hangover symptoms than vodka at the same alcohol dose. However, actual intoxication and impairment during drinking were not significantly different between the two. In other words, dark and light spirits get you equally drunk, but the darker ones may leave you feeling worse the next day.
Warm Drinks Versus Cold Drinks
There’s a persistent belief that warm alcoholic drinks, like mulled wine or hot toddies, get you drunk faster. In a controlled study where participants drank hot and cold versions of the same alcoholic beverage, everyone perceived the hot drink as more potent. But actual blood alcohol levels showed no significant difference. The warmth creates a sensation of stronger effects without actually changing how much alcohol reaches your bloodstream.
Drinks That Catch People Off Guard
Some drinks are worth flagging because they’re easy to underestimate:
- Cocktails with multiple spirits: A margarita, Negroni, or Manhattan can contain two to three standard drinks in a single glass, especially at bars that pour generously.
- Frozen and blended drinks: Piña coladas, daiquiris, and similar blended cocktails mask alcohol behind sweetness and cold temperatures. You often can’t taste how strong they are.
- High-ABV beers: Imperial stouts, barleywines, and Belgian tripels can reach 10% to 14% ABV. A single pint of a 10% beer is the equivalent of two standard drinks.
- Fortified wines: Port, sherry, and vermouth range from 15% to 22% ABV, significantly stronger than table wine.
- Hard seltzers and flavored malt beverages: Most are 5% ABV (similar to beer), but some brands sell 8% or higher versions in tall cans that contain close to two standard drinks per can.
The bottom line is straightforward: what makes you drunk is ethanol, and every alcoholic drink contains it. How fast and how intensely you feel it depends on the drink’s concentration, carbonation, what you mixed it with, whether you ate, and how quickly you’re drinking. Paying attention to how many standard drinks you’re actually consuming, rather than counting glasses, gives you a much more accurate picture of where your blood alcohol is heading.
