As an expert sommelier and brewer, I can provide you with a detailed answer to the question of how much is in a fifth of vodka. Traditionally, a fifth of vodka referred to one-fifth of a gallon, which is equivalent to 25.6 US fluid ounces or 757 milliliters. This measurement was commonly used in the United States to denote the size of a standard bottle of vodka.
However, it is important to note that the term “fifth” no longer accurately reflects the volume of vodka in a bottle. In modern times, a fifth of vodka typically refers to a 750-milliliter bottle, which is the standard size for a wine bottle. This change in terminology occurred due to various factors, including metric conversions and standardization within the alcohol industry.
The decision to adopt the 750-milliliter size as the standard for a fifth of vodka was likely influenced by the wine industry, as this size is commonly used for wine bottles. It allows for consistency in packaging and distribution, making it easier for consumers to recognize and purchase their preferred brands.
In my personal experiences as a sommelier and brewer, I have encountered numerous brands of vodka packaged in 750-milliliter bottles. This size is convenient for both consumers and producers, as it provides an ample amount of vodka for personal use or social gatherings. It is also a size that can be easily transported and stored.
To summarize, a fifth of vodka traditionally referred to one-fifth of a gallon, equaling 25.6 US fluid ounces or 757 milliliters. However, in modern times, a fifth of vodka is commonly understood to be a 750-milliliter bottle, which is the standard size for wine bottles. This change in terminology reflects the industry's move towards standardization and convenience for consumers.
