A debate surrounds the practice of adding ice to beer, particularly its origins and appropriateness. The practice is common in tropical regions like Vietnam, where it helps keep inexpensive beers cold. This is less relevant with higher-quality, more expensive beers. One reader suggests the practice originated in France, while another recounts seeing it in Thailand over 40 years ago. The origin remains uncertain. Adding ice to cheap beer is widely accepted in certain cultures. However, it's less common with craft beers. The reader from Vietnam wouldn't add ice to premium beers but wouldn't judge those who do. The article highlights a cultural difference in beer consumption. The practice's suitability depends on the beer's quality and the drinker's preferences.
