Yes, you can put Smirnoff vodka in the freezer. In fact, many people prefer to store vodka, including Smirnoff, in the freezer because it can enhance the drinking experience for some.
When you put vodka in the freezer, it doesn't freeze solid due to its alcohol content. Instead, it becomes very cold, and the low temperature can enhance the smoothness and mellow out any sharp or harsh flavors in the vodka. Cold temperatures can also reduce the intensity of alcohol's taste and aroma, making it more enjoyable for some individuals.
Keep in mind that vodka, like other spirits, has a very low freezing point (around -27 degrees Celsius or -17 degrees Fahrenheit) because of its high alcohol content. So, it will remain in a liquid state even in a freezer set at normal temperatures. However, if your freezer is set at extremely low temperatures, it's possible for the vodka to develop some ice crystals, but this doesn't affect its quality.
If you prefer to have your vodka at room temperature, that's also perfectly fine. It's all a matter of personal preference. Some people enjoy the smoothness and slight sweetness that come from drinking vodka at room temperature, while others prefer the cold, refreshing taste from storing it in the freezer.
Regardless of how you choose to store and enjoy your Smirnoff vodka, remember to always drink responsibly.
