As a connoisseur of spirits and a professional in the field of mixology, I have had the pleasure of exploring the vast world of alcoholic beverages. When it comes to the comparison between rum and vodka, it's a topic that can be quite nuanced and subjective, depending on the specific types and brands of each spirit. However, I will provide a detailed analysis based on the general characteristics of these two spirits.
Step 1: English Answer
Rum and vodka are both distilled spirits, but they differ significantly in their production process, ingredients, and resulting flavors. Let's delve into the factors that contribute to the sweetness and smoothness of these spirits.

Ingredients and Production:
Rum is primarily made from molasses or sugarcane juice, which inherently gives it a sweet profile. The production process involves fermenting the sugarcane byproducts and then distilling the resulting liquid. The sweetness in rum can vary greatly depending on whether it's made from molasses or directly from sugarcane juice. Molasses-based rums tend to be darker and sweeter, while sugarcane juice rums can be lighter and more subtle in sweetness.

On the other hand, vodka is typically made from a variety of sources such as grains (wheat, rye, corn), potatoes, or even fruits. The key to vodka's character is its distillation process, which is designed to strip away impurities and flavors, resulting in a spirit that is neutral and clean. The multiple distillations and the use of charcoal filtration in many cases contribute to a spirit that is smooth but not inherently sweet.

Flavor Profiles:
The flavor profile of rum is generally rich and complex, with notes of vanilla, caramel, toffee, and sometimes fruit or spice, depending on the aging process and the type of barrels used for maturation. Aged rums, in particular, can develop a deep sweetness from the sugars that caramelize within the barrel.

Vodka, in contrast, is known for its clean and crisp taste. It is mild in flavor, with little to no sweetness unless specifically crafted to be so. The goal with vodka is to provide a spirit that can be mixed with other ingredients without dominating the flavor profile of the cocktail.

Sweetness and Smoothness:
When comparing the two spirits neat or by itself, rum is often perceived as sweeter due to its sugarcane origins. The sweetness of rum can be quite pronounced, especially in the case of spiced rums or liqueurs that have added flavors and sugars.

Vodka, however, is not typically associated with sweetness unless it has been flavored or sweetened. Its smoothness comes from the distillation and filtration processes, which remove most of the congeners that can cause a harsh or burning sensation.

Cocktail Applications:
Vodka's lack of strong flavor makes it a popular choice for cocktails. It can be mixed with a wide array of other flavors without altering the intended taste of the cocktail significantly. This versatility is one of the reasons why vodka is a staple in many bars and households.

Rum, with its distinct sweetness and flavors, can also be used in cocktails, but it often plays a more dominant role in the mix. It can add a unique sweetness and depth of flavor to cocktails, which is particularly suitable for tropical or tiki-style drinks.

Conclusion:
In conclusion, rum is generally sweeter and has a smoother taste when compared to vodka, primarily due to its sugarcane base and the influence of the aging process. Vodka, with its neutral flavor profile, is designed to be smooth and clean, making it an ideal spirit for mixing in a variety of cocktails. The choice between the two comes down to personal preference and the intended use of the spirit.
