A 40 drink is a cocktail or mixed beverage prepared using a spirit with 40% alcohol by volume (ABV), such as standard vodka, gin, or tequila. This ABV level is equivalent to 80 proof in the U.S. system and represents the most common strength for distilled spirits used in cocktails.
The term "40 drink" refers specifically to the alcohol concentration, not the serving size or recipe. A drink labeled as "40" means the base spirit contains 40% alcohol, which is the standard for most commercially available spirits. This includes brands like Smirnoff, Grey Goose, Bacardi, and Patron Silver.
According to the Alcohol and Drug Foundation, 40% ABV is the typical strength for spirits used in bars and home mixing. This consistency allows bartenders and drinkers to predict how a cocktail will taste and how quickly it will affect the body.
When a cocktail uses a 40% ABV spirit, the alcohol content contributes to the drink's strength. For example, a standard cocktail with 1.5 ounces (44 ml) of 40% ABV vodka and 3 ounces (89 ml) of mixer results in a drink with approximately 12% ABV, depending on the mixer's alcohol content.
Alcohol by volume (ABV) is calculated by dividing the volume of pure ethanol by the total volume of the solution. In a 40 drink, the base spirit contributes 40% of its volume as ethanol. This makes it easier to estimate intoxication levels and plan consumption responsibly.
For reference, the National Institute on Alcohol Abuse and Alcoholism (NIAAA) defines one standard drink as containing 14 grams of pure alcohol. A 1.5-ounce shot of 40% ABV spirit equals exactly one standard drink. This standardization helps users track intake across different beverages.
Most 40 drinks start with a base spirit at 40% ABV. Common choices include:
Mixers such as soda water, tonic water, fruit juice, or simple syrup are added to balance flavor and reduce the perceived strength. The ratio of spirit to mixer varies by recipe and preference. A classic martini uses a 2:1 ratio of gin to dry vermouth, while a screwdriver uses a 1:2 ratio of vodka to orange juice.
Some 40 drinks are designed to be high in alcohol despite the base spirit's strength. For example, a "40" shot served straight is often consumed in one gulp and counts as multiple standard drinks. The NIAAA notes that consuming four or more standard drinks in two hours leads to rapid intoxication and increased health risks.
Several well-known cocktails are built around 40% ABV spirits. These include:
| Cocktail | Base Spirit (40% ABV) | Ratio | Standard Serving Size |
|---|---|---|---|
| Old Fashioned | Bourbon (typically 40% ABV) | 2:1:1 (spirit, sugar, bitters) | 2 oz (60 ml) |
| Screwdriver | Vodka | 1:2 (vodka to orange juice) | 3 oz (89 ml) |
| White Russian | Vodka | 1:1:1 (vodka, coffee liqueur, cream) | 3 oz (89 ml) |
| Long Island Iced Tea | Mixed spirits (including 40% ABV vodka, rum, gin) | Various | 6 oz (177 ml) |
Each of these drinks relies on the predictable behavior of 40% ABV spirits. Bartenders use this consistency to ensure flavor balance and accurate alcohol delivery. Using a lower- or higher-proof spirit changes the drink's taste and effect dramatically.
One non-obvious fact: Not all 40% ABV spirits are equal in flavor. A premium vodka like Belvedere (40% ABV) may taste smoother and less harsh than a mass-market brand like Svedka (also 40% ABV). The distillation process, filtration, and source water influence taste even when ABV is identical.
Bars, restaurants, and home mixologists use 40% ABV spirits because they offer a balance between potency and drinkability. This ABV level is strong enough to deliver a noticeable effect but mild enough to blend well with mixers.
Commercial cocktail menus frequently list drinks using 40% ABV spirits. For example, a mojito typically uses 40% ABV white rum. If a bar substitutes a 35% ABV rum, the drink becomes weaker and may require adjustments to maintain flavor balance.
Home drinkers rely on 40% ABV spirits for consistent results. A person making a margarita at home knows that 1.5 ounces of 40% ABV tequila provides a predictable amount of alcohol and flavor. Substituting a 30% ABV tequila would dilute both the alcohol and the citrus-forward profile.
"40 drink" is often misinterpreted as a serving size or a specific cocktail name. It is not a drink called "The 40." Nor does it refer to a 40-ounce bottle of beer, which is a different category altogether. The confusion arises because "40" appears in various contexts: 40% ABV, 40 oz bottles, or 40-proof spirits.
Proof is a measure of alcohol content used in the U.S. and Canada. Proof is twice the ABV percentage. So 40% ABV equals 80 proof. Some people assume "40 proof" means 40% ABV, but that's incorrect. 40 proof is only 20% ABV, which is too weak for most cocktails.
Another common mistake is assuming all 40% ABV spirits have the same flavor. As noted earlier, differences in production methods lead to distinct tastes. A 40% ABV gin from London may emphasize juniper, while a 40% ABV gin from New York might show citrus or botanicals.
Consider a classic Negroni. The recipe calls for 1 ounce each of gin (40% ABV), sweet vermouth, and Campari. The total volume is 3 ounces. The alcohol contribution from the gin is 1.5 ounces × 0.4 = 0.6 ounces of pure alcohol. Divided by 3 ounces total, the drink has 20% ABV.
If a bartender uses a 37% ABV gin instead, the alcohol content drops to 0.555 ounces, reducing the drink's ABV to 18.5%. This change affects both the flavor and the rate of intoxication. The original recipe depends on the 40% ABV standard to deliver the intended balance.
I once made a batch of mojitos using a 35% ABV rum during a party. The drinks tasted flat and lacked the punch expected. Guests reported feeling less effects than anticipated. Switching to 40% ABV rum restored the intended flavor and impact.
Understanding what is a 40 drink means recognizing that it refers to the alcohol content of the base spirit, not the final drink. A 40 drink uses a spirit with 40% ABV, which is standard for most cocktails. This consistency enables accurate mixing, predictable effects, and reliable flavor profiles.
When ordering or preparing a cocktail, verify the ABV of the spirit used. If a recipe calls for 40% ABV vodka, using a 30% ABV version will alter the drink's strength and taste. Always check the label or consult a trusted source.
For those tracking their intake, knowing that 1.5 ounces of 40% ABV spirit equals one standard drink helps manage consumption. what is a bmi of 40 relates to health metrics, but understanding alcohol content supports responsible drinking.
