Brand Consistency for Vodka Distilleries

Not all vodka comes in plastic handles, and even if it does, quality control is an essential element of the production process. After repeated distillation, manufacturers subject their batches to a battery of QC tests designed to ensure color clarity, transparency, and the flavor is consistent with their brand. Only after passing this regimen is the vodka bottled and shipped to distributors.

The reason for this is obvious: brand consistency. A major selling point for middle and top-shelf vodka companies is their comparative quality and distinctive flavor, or lack thereof. Should they ship out batches of off-color vodka, customers are likely to choose a different option off the shelf. These customers will also remember the decision and will be more likely to choose another brand in the future. That holds true even if the batch in front of them is the color it’s supposed to be.

Customers won’t notice haze or strange flavors until after they’ve bought the bottle, or received a drink at the bar. However, they’ll remember the experience and will be more likely to choose a different brand the next time they’re looking for a drink. Quality control then is not only important for the immediate batch, but to safeguard the reputation of every other future batch as well.

Instrumental Color and Haze Measurement Ensures Vodka Quality Control 

With their brand’s reputation at stake, vodka producers rely on transmission spectrophotometers and haze measurement instruments to ensure that their liquor is the right color and completely transparent. These instruments measure color and haze, respectively, using similar methods. They pass a controlled beam of light through a transparent liquid and record any changes in the light as it hits a detector on the other side. Quality control technicians place the sample into the instrument, take the measurement, and observe the result displayed on the instrument’s screen. It is a straightforward method for determining if the sample color (or lack thereof) is within acceptable tolerances.
