A typical margarita contains about 1.5 standard drinks’ worth of alcohol, so yes, it packs more than a single standard drink. That extra half-drink adds up quickly if you’re counting, and restaurant versions can push even higher depending on the pour and the glass size.
What Counts as a Standard Drink
In the United States, one standard drink contains 0.6 fluid ounces (14 grams) of pure alcohol. That’s the amount found in 12 ounces of regular beer at 5% ABV, 5 ounces of wine at 12% ABV, or a single 1.5-ounce shot of 80-proof liquor. These benchmarks exist so people can compare different types of alcohol on equal footing, regardless of what’s in the glass.
Why a Margarita Exceeds One Standard Drink
A classic margarita uses a 3-2-1 ratio: three parts tequila, two parts orange liqueur (such as triple sec or Cointreau), and one part fresh lime juice. In a single serving, that typically means about 2 ounces of tequila and a little over 1 ounce of orange liqueur. Both of those ingredients carry significant alcohol. Tequila is 40% ABV, and orange liqueurs range from 20% to 40% ABV depending on the brand. Cointreau, for example, sits at 40%, while budget triple sec is closer to 20%.
Because you’re combining two separate spirits, the total ethanol in the glass exceeds what you’d get from a single 1.5-ounce shot. The lime juice and any added sweetener dilute the drink’s strength by volume, but they don’t reduce the actual amount of alcohol. That’s how a standard margarita lands at roughly 1.5 standard drinks, even though it might feel like “just one cocktail.”
Restaurant Pours vs. Homemade
The 1.5-standard-drink estimate assumes a conservatively mixed margarita. At restaurants and bars, servings tend to be larger. A listed 4-ounce margarita at a chain like Applebee’s might seem modest, but many establishments serve 8- to 12-ounce glasses, especially when the drink is shaken over ice or blended. The more liquid in the glass, the more room for extra tequila or liqueur.
Homemade margaritas give you more control over the pour, but they come with their own trap: free-pouring without a jigger often leads to heavier shots than you’d expect. If you’re making them at home and want to track your intake accurately, measuring each ingredient is the simplest fix. A margarita made with exactly 1.5 ounces of tequila and 0.75 ounces of a lower-proof triple sec (20% ABV) will land closer to one standard drink, while a version with 2 ounces of tequila and an ounce of Cointreau at 40% ABV pushes well past 1.5.
Frozen vs. On the Rocks
Frozen margaritas generally contain more alcohol than their on-the-rocks counterparts. The blended ice and added mixers increase the total volume of the drink, which means bartenders often compensate with a heavier pour of tequila and liqueur to keep the flavor from tasting watered down. The slushy texture also masks the bite of alcohol, making it easy to drink faster and order another round without realizing how much you’ve consumed.
On-the-rocks versions, served over ice cubes in a shorter glass, tend to be smaller and more spirit-forward. You taste the alcohol more directly, which naturally slows most people down. If keeping your intake predictable matters to you, an on-the-rocks margarita is the easier one to gauge.
How This Affects Drinking Guidelines
The CDC defines moderate drinking as two drinks or fewer per day for men and one drink or fewer per day for women, where “drink” means one standard drink. Because a single margarita is already about 1.5 standard drinks, one margarita puts a woman at or above the daily moderate limit, and two margaritas put a man over his.
This math matters more than most people realize during a night out. Ordering “just two margaritas” at dinner actually amounts to roughly three standard drinks. If the restaurant serves oversized portions, that number climbs further. Keeping track is simpler if you think in terms of total alcohol rather than number of glasses.
Quick Comparison by Drink Type
- Regular beer (12 oz, 5% ABV): 1 standard drink
- Glass of wine (5 oz, 12% ABV): 1 standard drink
- Shot of tequila (1.5 oz, 40% ABV): 1 standard drink
- Classic margarita (homemade, standard recipe): ~1.5 standard drinks
- Restaurant margarita (large pour): 2 or more standard drinks
The bottom line is straightforward: a margarita is not “one drink” in the way public health guidelines use the term. The combination of tequila and orange liqueur puts it at about one and a half standard drinks at minimum, and the way most bars and restaurants serve them, it’s often closer to two.
