The question of what's stronger, Captain Morgan or vodka, isn't as simple as it seems. While many spirits are standardized at a certain proof, both Captain Morgan and vodka can be found in a range of alcohol concentrations. Understanding the nuance requires looking at the typical ABV of each and exploring how specific product variations affect the final potency.
Captain Morgan: More Flavor, Less Alcohol?
Captain Morgan is a brand name, and its most popular product, Original Spiced Rum, is typically sold at 35% ABV, or 70 proof in the U.S.. This is lower than the 40% ABV standard for many distilled spirits. The sweet, spiced flavor profile of Captain Morgan can also lead consumers to perceive it as less potent than a neutral spirit like vodka, which lacks strong flavoring to mask the taste of alcohol. This perception is a key reason many believe vodka to be the stronger of the two.
However, it is important to remember that not all Captain Morgan products have the same alcohol content. For example, Captain Morgan 100 Proof Spiced Rum is a much stronger variant, bottled at 50% ABV (100 proof), which is higher than most standard vodkas. This shows that while the most common Captain Morgan product is weaker, the brand also offers more potent options that defy the usual comparison.
Vodka: The Potency Standard-Bearer
Vodka's reputation for strength comes from its often neutral taste and high standard alcohol content. In the United States and European Union, vodka must be bottled at a minimum of 40% ABV (80 proof). Many premium vodkas also adhere to this standard, making 40% ABV the baseline expectation for the spirit. This means a standard vodka is indeed stronger than Captain Morgan's Original Spiced Rum.
Yet, vodka's strength range is quite broad. While 40% ABV is the minimum, some specialty or high-proof vodkas can be found with much higher percentages, sometimes ranging up to 95% ABV. These are often sold as neutral grain spirits and are significantly more potent than any common Captain Morgan product. The variety in vodka's potential strength, from standard to extremely high-proof, means it has a much higher ceiling for potency than most rums.
Comparing Potency: Captain Morgan vs. Vodka
Here is a quick comparison of the typical and maximum alcohol content for Captain Morgan and vodka based on Alcohol by Volume (ABV):
| Attribute | Captain Morgan Original Spiced Rum | Standard Vodka | Overproof Vodka | Captain Morgan 100 Proof |
|---|---|---|---|---|
| Typical ABV | 35% | 40% | N/A | 50% |
| Typical U.S. Proof | 70 | 80 | N/A | 100 |
| Highest ABV | 50% (100 proof variant) | Up to 95% | Up to 95% | 50% (100 proof variant) |
| Overall Strength | Lower than standard vodka | Higher than most Captain Morgan | Potentially much higher than both | Higher than standard vodka |
What Determines Alcohol Content?
The final alcohol content of any spirit is determined by the distillation process and any subsequent dilution. After fermentation, the alcohol is separated and concentrated through distillation. For both rum and vodka, this can be done using either a pot still (producing more flavor) or a column still (producing a more neutral spirit).
- Distillation: While a rum-like Captain Morgan and a vodka are both distilled, a higher-proof vodka will undergo more rectification (purification) to produce a cleaner, more neutral spirit.
- Flavoring and Additives: Captain Morgan is a spiced rum, meaning flavors and sugar are added to the finished product, which inherently lowers the ABV relative to an unflavored spirit that is simply diluted with water. The addition of these ingredients contributes to its character but also to its lower potency compared to a standard, unflavored vodka.
- Dilution: Both spirits are typically diluted with water to reach their final, desired bottling proof. However, the initial spirit base for high-proof vodka is much stronger, allowing for a wider range of final products.
Conclusion
In a direct comparison of the most common versions, a standard bottle of vodka is stronger than Captain Morgan Original Spiced Rum, with a 40% ABV versus 35% ABV, respectively. However, this simple answer hides the variability within each category. The strongest variations of vodka, known as high-proof or neutral grain spirits, can reach up to 95% ABV, making them far more potent than any common Captain Morgan product. Captain Morgan does offer a stronger, 100-proof variant (50% ABV), which is stronger than standard vodka but not as strong as the most potent vodka varieties available. Ultimately, perceived strength can be misleading, and the actual ABV listed on the bottle is the only reliable measure of a spirit's potency.

Frequently Asked Questions
Is Captain Morgan or vodka stronger per shot?
A standard shot of vodka (1.5 oz at 40% ABV) contains more alcohol than a standard shot of Captain Morgan Original Spiced Rum (1.5 oz at 35% ABV).
Why does Captain Morgan taste less strong than vodka?
Captain Morgan's taste includes added vanilla and spice flavorings, which can mask the flavor of the alcohol, making it taste smoother and less potent than vodka, which is a neutral spirit with a more pronounced alcohol flavor.
Are all types of Captain Morgan weaker than all types of vodka?
No, while Captain Morgan Original Spiced Rum is weaker than standard vodka, the brand also produces higher-proof varieties like Captain Morgan 100 Proof, which is 50% ABV and stronger than most standard vodkas.
What is 'overproof' rum and how does it compare to vodka?
Overproof rum is bottled at a higher alcohol content, typically at least 57.5% ABV, and can have a much higher alcohol concentration than standard vodka. Some overproof rums can be 80% ABV or higher.
Can vodka be stronger than 90 proof?
Yes, some specialty or high-proof vodkas are available well above 90 proof (45% ABV), with some brands producing neutral grain spirits that can reach up to 192 proof (96% ABV).
Does the country of origin affect the strength of vodka or rum?
Yes, regulations vary by country. The EU minimum for vodka is 37.5% ABV, while the US requires 40% ABV. The EU minimum for rum is also 37.5% ABV.
Does mixing Captain Morgan or vodka with a mixer affect its strength?
Yes, mixing any spirit with a non-alcoholic beverage dilutes the alcohol content and reduces the overall ABV of the final drink.
