The time it takes for a bottle of beer to freeze in a standard household freezer can vary depending on several factors, such as the initial temperature of the beer, the temperature setting of the freezer, and the efficiency of the freezer itself. However, under typical conditions, it usually takes about 1 to 3 hours for a standard 12-ounce (355 ml) bottle of beer to freeze in a standard home freezer set at 0°F (-18°C).
Keep in mind that carbonated beverages like beer can have a lower freezing point due to the dissolved carbon dioxide gas, which can slow down the freezing process slightly compared to non-carbonated liquids. Also, if the freezer is packed with other items or if the beer bottle is placed near the back or sides of the freezer where the cooling is less efficient, it might take a bit longer to freeze.
To avoid any potential mess from a frozen and potentially burst bottle, it's best to monitor the beer's temperature regularly and take it out of the freezer once it reaches the desired level of chilliness without actually freezing.
