As an expert sommelier and brewer, I can confidently say that vodka is indeed supposed to be tasteless. According to Title 27 of the US Standards of Spirit Identity, as well as the requirements in Russia, vodka must be distilled to 190 proof, which is equivalent to 95% alcohol. The remaining 5% is typically water. This high level of alcohol content is what gives vodka its characteristic tastelessness, with the only flavor being that of ethanol.
The process of distillation plays a crucial role in achieving the desired tasteless nature of vodka. Distillation involves heating a liquid (in this case, a fermented grain or potato mash) to create steam, which is then collected and condensed back into a liquid form. Through this process, impurities and unwanted flavors are removed, resulting in a clean and pure spirit.
It is important to note that the tastelessness of vodka does not imply a lack of quality or craftsmanship. On the contrary, achieving a neutral flavor profile requires skillful distillation techniques and the use of high-quality ingredients. The goal is to create a spirit that is smooth, clean, and devoid of any distinct flavors or aromas.
However, it is worth mentioning that there may be subtle variations in taste among different vodka brands. While the primary objective is to achieve a neutral taste, some vodkas may exhibit slight nuances derived from the base ingredients used or the specific distillation process employed. These nuances, though subtle, can be appreciated by discerning vodka enthusiasts.
Personal experience-wise, I have had the opportunity to taste and evaluate a wide range of vodkas throughout my career. From well-known brands to small-batch artisanal productions, the common thread among all of them is the absence of pronounced flavors. Vodka is meant to be a versatile spirit that can be enjoyed on its own or as a base for cocktails, allowing other ingredients to take center stage.
Vodka is indeed supposed to be tasteless, with the flavor of ethanol being its most prominent characteristic. The stringent regulations and distillation processes ensure that the final product is clean, pure, and devoid of any distinct flavors. While there may be subtle variations among different brands, the overarching goal of vodka production is to create a neutral spirit that serves as a blank canvas for mixologists and cocktail enthusiasts to explore their creativity.
