Alcoholic seltzers can freeze if the temperature is low enough. The freezing point of an alcoholic seltzer depends on its alcohol content and other ingredients, such as sugar or flavorings. The freezing point of an alcoholic seltzer can also be affected by its carbonation level.
In general, alcoholic seltzers that contain a higher alcohol content will have a lower freezing point than those with a lower alcohol content. Seltzers that contain sugar or other sweeteners may also have a lower freezing point than those without.
It is important to note that freezing an alcoholic seltzer can sometimes alter its taste and texture, and can also cause the formation of ice crystals that may affect its appearance. In addition, frozen alcoholic seltzers can pose a risk of freezer burn if they are not properly stored and sealed.
If you are unsure whether an alcoholic seltzer has been frozen, it is recommended to inspect it for signs of freezer burn or changes in texture or taste before consuming it.
